  • Hiding Command Prompt with CodeDomProvider

    - by j-t-s
    Hi All I've just got my own little custom c# compiler made, using the article from MSDN. But, when I create a new Windows Forms application using my sample compiler, the MSDOS window also appears, and if I close the DOS window, my WinForms app closes too. How can I tell the Compiler? not to show the MSDOS window at all? Thank you :) Here's my code: using System; namespace JTS { public class CSCompiler { protected string ot, rt, ss, es; protected bool rg, cg; public string Compile(String se, String fe, String[] rdas, String[] fs, Boolean rn) { System.CodeDom.Compiler.CodeDomProvider CODEPROV = System.CodeDom.Compiler.CodeDomProvider.CreateProvider("CSharp"); ot = fe; System.CodeDom.Compiler.CompilerParameters PARAMS = new System.CodeDom.Compiler.CompilerParameters(); // Ensure the compiler generates an EXE file, not a DLL. PARAMS.GenerateExecutable = true; PARAMS.OutputAssembly = ot; PARAMS.CompilerOptions = "/target:winexe"; PARAMS.ReferencedAssemblies.Add(typeof(System.Xml.Linq.Extensions).Assembly.Location); PARAMS.LinkedResources.Add("this.ico"); foreach (String ay in rdas) { if (ay.Contains(".dll")) PARAMS.ReferencedAssemblies.Add(ay); else { string refd = ay; refd = refd + ".dll"; PARAMS.ReferencedAssemblies.Add(refd); } } System.CodeDom.Compiler.CompilerResults rs = CODEPROV.CompileAssemblyFromFile(PARAMS, fs); if (rs.Errors.Count > 0) { foreach (System.CodeDom.Compiler.CompilerError COMERR in rs.Errors) { es = es + "Line number: " + COMERR.Line + ", Error number: " + COMERR.ErrorNumber + ", '" + COMERR.ErrorText + ";" + Environment.NewLine + Environment.NewLine; } } else { // Compilation succeeded. es = "Compilation Succeeded."; if (rn) System.Diagnostics.Process.Start(ot); } return es; } } }

  • Qt - no such signal error

    - by bullettime
    I'm trying to trigger a signal when a double click happens in one of the draggable widgets on the fridge magnets example. Here's the changes I made to the example source: DragLabel: class DragLabel : public QLabel { public: DragLabel(const QString &text, QWidget *parent); QString labelText() const; public slots: void testSlot(){qDebug()<<"testSlot";} //<-- implemented this slot protected: void mouseDoubleClickEvent(QMouseEvent *ev){emit testSignal();} //<-- overriden this method private: QString m_labelText; signals: void testSignal(); //<-- added this signal }; The only thing I changed in the implementation file is adding connect(this,SIGNAL(testSignal()),this,SLOT(testSlot())); to DragLabel's constructor. Trying to compile the project resulted in 'undefined reference to `DragLabel::testSignal()' and 'collect2: ld returned 1 exit status' errors. When I comment out the call to the signal, it compiles and runs, but gives off 'Object::connect: No such signal QLabel::testSignal() in draglabel.cpp' warning in the application output. Apparently testSignal() isn't being recognized as a signal. What am I missing?

  • Modifying UINavigation Bar Buttons in SubViews

    - by james
    I'm having trouble trying to modify the navigation bar in the subview portion of my application. self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(add_Clicked:)] autorelease]; I have no issues modifying the navigation bar in any of my UIViewControllers classes. The simplified application class outline is as such: AppDelegate - UIViewControllerA (has a left and a right navigationBarButton) - Subview is displayed when a SegmentControl is selected. (Within the subview, I'm trying to modify the right NavigationBarButton that is displayed) [self.view addSubview:newControllerName.view]; Methods I have attempted: Trying to set self.navigationItem.rightBarButtonItem within my subview to a new UIBarButtonItem. Creating a pointer to UIViewControllerA within my AppDelegate. The UIViewControllerA contains a function setNavButton I wrote to set the rightBarButtonItem to a button. Then I am referencing the AppDelegate's reference to UIViewControllerA and attempting to call setNavButton. I included a NSLog call to see if that function is being called and it is executing but the NavigationBar isn't being modified. I'm trying to avoid having to push a UIViewController after the SegmentControl is clicked in UIViewControllerA so that I can simulate the SegmentControl as tabs. I'm not getting any errors during compile or run time. Anyone have any ideas?

  • How to have a policy class implement a virtual function?

    - by dehmann
    I'm trying to design a policy-based class, where a certain interface is implemented by the policy itself, so the class derives from the policy, which itself is a template (I got this kind of thinking from Alexandrescu's book): #include <iostream> #include <vector> class TestInterface { public: virtual void test() = 0; }; class TestImpl1 { public: void test() {std::cerr << "Impl1" << std::endl;} }; template<class TestPolicy> class Foo : public TestInterface, TestPolicy { }; Then, in the main() function, I call test() on (potentially) various different objects that all implement the same interface: int main() { std::vector<TestInterface*> foos; foos.push_back(new Foo<TestImpl1>()); foos[0]->test(); delete foos[0]; return 0; } It doesn't compile, though, because the following virtual functions are pure within ‘Foo<TestImpl1>’: virtual void TestInterface::test() I thought TestInterface::test() is implemented because we derive from TestImpl1?

  • Linking the Linker script file to source code

    - by user304097
    Hello , I am new to GNU compiler. I have a C source code file which contains some structures and variables in which I need to place certain variables at a particular locations. So, I have written a linker script file and used the __ attribute__("SECTION") at variable declaration, in C source code. I am using a GNU compiler (cygwin) to compile the source code and creating a .hex file using -objcopy option, but I am not getting how to link my linker script file at compilation to relocate the variables accordingly. I am attaching the linker script file and the C source file for the reference. Please help me link the linker script file to my source code, while creating the .hex file using GNU. /*linker script file*/ /*defining memory regions*/ MEMORY { base_table_ram : org = 0x00700000, len = 0x00000100 /*base table area for BASE table*/ mem2 : org =0x00800200, len = 0x00000300 /* other structure variables*/ } /*Sections directive definitions*/ SECTIONS { BASE_TABLE : { } > base_table_ram GROUP : { .text : { } { *(SEG_HEADER) } .data : { } { *(SEG_HEADER) } .bss : { } { *(SEG_HEADER) } } > mem2 } C source code: const UINT8 un8_Offset_1 __attribute__((section("BASE_TABLE"))) = 0x1A; const UINT8 un8_Offset_2 __attribute__((section("BASE_TABLE"))) = 0x2A; const UINT8 un8_Offset_3 __attribute__((section("BASE_TABLE"))) = 0x3A; const UINT8 un8_Offset_4 __attribute__((section("BASE_TABLE"))) = 0x4A; const UINT8 un8_Offset_5 __attribute__((section("BASE_TABLE"))) = 0x5A; const UINT8 un8_Offset_6 __attribute__((section("SEG_HEADER"))) = 0x6A; My intention is to place the variables of section "BASE_TABLE" at the address defined i the linker script file and the remaining variables at the "SEG_HEADER" defined in the linker script file above. But after compilation when I look in to the .hex file the different section variables are located in different hex records, located at an address of 0x00, not the one given in linker script file . Please help me in linking the linker script file to source code. Are there any command line options to link the linker script file, if any plese provide me with the info how to use the options. Thanks in advance, SureshDN.

  • HtmlAgilityPack - Vs 2010 - c# ASP - File Not found

    - by Janosch Geigowskoskilu
    First, I've already searched the web & StackOverflow for hours, and i did find a lot about troubleshooting HtmlAgilityPack and tried most of these but nothing worked. The Situation: I'm developing a C# ASP .NET WebPart in SharePoint Foundation. Everything works fine, now I want to Parse a HTML Page to get all ImagePaths and save the Images on HD/Temp. To do that I was downloading HtmlAgilityPack, current version, add reference to Project, everything looks OK, IntelliSense works fine. The Exception: But when I want to run the section where HtmlAgilityPack should be used my Browser shows me a FileNotFoundException - The File or Assembly could not be found. What I tried: After first searches i tried to include v1.4.0 of HtmlAgilityPack cause I read that the current version in some case is not really stable. This works fine to until the point I want to use HtmlAgilityPack, the same Exception. I also tried moving the HtmlAgilityPack direct to the Solution directory, nothing changed. I tried to insert HtmlAgilityPack via using and I tried direct call e.g. HtmlAgilityPack.HtmlDocument. Conclusion : When I compile no error occurs, the reference is set correct. When I trace the HtmlAgilityPack.dll with ProcMon the Path is shown correct, but sometimes the Result is 'File Locked with only Readers' but I don't know enough about ProcMon to Know what this means or if this is critical. It couldn't have something to do with File Permissions because if I check the DLL the permissions are all given.

  • Optimize Use of Ramdisk for Eclipse Development

    - by Eric J.
    We're developing Java/SpringSource applications with Eclipse on 32-bit Vista machines with 4GB RAM. The OS exposes roughly 3.3GB of RAM due to reservations for hardware etc. in the virtual address space. I came across several Ramdisk drivers that can create a virtual disk from the OS-hidden RAM and am looking for suggestions how best to use the 740MB virtual disk to speed development in our environment. The slowest part of development for us is compiling as well as launching SpringSource dm Server. One option is to configure Vista to swap to the Ramdisk. That works, and noticeably speeds up development in low memory situations. However, the 3.3GB available to the OS is often sufficient and there are many situations where we do not use the swap file(s) much. Another option is to use the Ramdisk as a location for temporary files. Using the Vista mklink command, I created a hard link from where the SpringSource dm Server's work area normally resides to the Ramdisk. That significantly improves server startup times but does nothing for compile times. There are roughly 500MB still free on the Ramdisk when the work directory is fully utilized, so room for plenty more. What other files/directories might be candidates to place on the Ramdisk? Eclipse-related files? (Parts of) the JDK? Is there a free/open source tool for Vista that will show me which files are used most frequently during a period of time to reduce the guesswork?

  • Java EE6 App + EJB in Glassfish 3.0/Netbeans 6.8?

    - by egbokul
    Has anyone got this configuration working? Latest Netbeans, latest Glassfish, I created an EJB project, also an EE Application. The EJB in itself builds & deploys to Glassfish OK. Now when I want to reference the EJB, I have to add the EJB jar to the EE Application path, if I don't do this the code does not compile. But, the EJB jar gets packaged in the App jar and as a result when I try to deploy the app to Glassfish it says: "java.lang.IllegalArgumentException: Sniffers with type [ejb] and type [appclient] should not claim the archive at the same time. Please check the packaging of your archive" How do I tell Netbeans NOT TO package the EJB in the App jar? Or is the problem somewhere else? btw. if I remove the EJB manually from the JAR then the app deploys successfully (with asadmin deploy), but when I try to run it with appclient, I get a NullPointerException. Surely there must be a solution to this, I thought Netbeans was for web application development after all...

  • C question: error: expected ')' before '*' token

    - by lhw
    ===EDIT I apologize for not putting the pcb struct into the code snippet. There is a struct called pcb defined in above the two structs I originally posted. Namely, typedef struct{ UINT32 proc; struct pcb *link; }pcb; Hi, I asked a question regarding structs in C a few minutes ago and got an answer blazing fast. But now I'm facing another problem, namely the error in the title of this question. I'm trying to implement a simple priority queue in C using arrays of queues. However, when I try to declare a function on pcb_pQ structure, I get the above error. I have the structs clearly defined in the heard file. In the header file: typedef struct{ pcb *head; pcb *tail; SINT32 size; } pcb_Q; typedef struct pcb_pQ { pcb_Q queues[5]; SINT32 size; } pcb_pQ; Function prototype in header file: /*priority queue operations*/ VOID pcb_pq_enqueue(pcb_pQ*, pcb*); Function impelmentation in .c file: VOID pcb_pq_enqueue(pcb_pQ* pcb_pQ, pcb* pcb) { pcb_Q* pcb_Q_p; int priority; priority = pcb->proc_priority; pcb_Q_p = &pcb_pQ->queues[priority]; pcb_enqueue(pcb_Q_p, pcb); } When I try to compile the above code, I get an "error: expected ')' before '*' token". This error is pointing to the function signature in the .c file, namely VOID pcb_pq_enqueue(pcb_pQ* pcb_pQ, pcb* pcb) { But I am not sure why I am getting this error, could someone give me a hand? Thanks a lot.

  • How can I reuse .NET resources in multiple executables?

    - by Brandon
    I have an existing application that I'm supposed to take and create a "mini" version of. Both are localized apps and we would like to reuse the resources in the main application as is. So, here's the basic structure of my apps: MainApplication.csproj /Properties/Resources.resx /MainUserControl.xaml (uses strings in Properties/Resources.resx) /MainUserControl.xaml.cs MiniApplication.csproj link to MainApplication/Properties/Resources.resx link to MainApplication/MainUserControl.xaml link to MainApplication/MainUserControl.xaml.cs MiniApplication.xaml (tries to use MainUserControl from MainApplication link) So, in summary, I've added the needed resources and user control from the main application as links in the mini application. However, when I run the mini application, I get the following exception. I'm guessing it's having trouble with the different namespaces, but how do I fix? Could not find any resources appropriate for the specified culture or the neutral culture. Make sure \"MainApplication.Properties.Resources.resources\" was correctly embedded or linked into assembly \"MiniApplication\" at compile time, or that all the satellite assemblies required are loadable and fully signed. FYI, I know I could put the user control in a user control library but the problem is that the mini application needs to have a small footprint. So, we only want to include what we need.

  • Print a string that contains a certain pattern in Java

    - by jjpotter
    I am trying to find a regular expression within a line of a .csv file, so I can eventually save all the matches to another file, and lose all the other junk. So a line in my file might look like: MachineName,User,IP,VariableData,Location The VariableData is what I want to match, and if there's a match, print the line. I am using a pattern for this because I only want 3 out of 10 of variations of VariableData, and out of those 3, they are numbered differently(example, "pc104, pccrt102, pccart65"). I am trying to do this using the Scanner Class and keeping it simple as possible so I can understand it. Here is where I was heading with this...(the pattern isn't complete, just have it like this for testing). import java.io.File; import java.util.Scanner; import java.util.regex.Pattern; public class pcv { public static void main(String[] args) { File myFile = new File("c:\\temp\\report.csv"); Pattern myPat = Pattern.compile("pc"); try{ Scanner myScan = new Scanner(myFile); while(myScan.hasNext()){ if(myScan.hasNext(myPat)){ System.out.println("Test"); } } }catch(Exception e){ } } } This code loops, im guessing the .hasNext() methods are resetting themselves. I've played around with the Matcher class a little bit, but only found a way to match the expression but not get the whole line. My other throught was maybe somehow count the line that contains the pattern, then go back and print the line that corresponds to the counts.

    I have installed a fresh copy of windows xp 2002 with SP2, and then VS.net 2008 enterprise edition. I am trying to build a simplest possible web application, and its not compiling giving error csc.exe not found. I googled a lot, and spot the problem in the following section in web.config : <system.codedom> <compilers> <compiler language="c#;cs;csharp" extension=".cs" warningLevel="4" type="Microsoft.CSharp.CSharpCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <providerOption name="CompilerVersion" value="v3.5"/> <providerOption name="WarnAsError" value="false"/> </compiler> <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" warningLevel="4" type="Microsoft.VisualBasic.VBCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <providerOption name="CompilerVersion" value="v3.5"/> <providerOption name="OptionInfer" value="true"/> <providerOption name="WarnAsError" value="false"/> </compiler> </compilers> </system.codedom> But if i remove the csharp compiler section , and then compile, it compiles fine with vb compiler section. And if I change the value from v3.5 to v2.0 in the of csharp section, then also it compiles fine. But then all my Linq Queries are not recognized by the compiler. But System.Linq and all classes present in it are accessible in the code. Please help in this weird behavior.

  • Is my heuristic algorithm correct? (Sudoku solver)

    - by Aposperite
    First of -yes this IS a homework- but it's primarily a theoretical question rather than a practical one, I am simply asking a confirmation if I am thinking correctly or any hints if I am not. I have been asked to compile a simple Sudoku solver (on Prolog but that is not so important right now) with the only limitation being that it must utilize a heuristic function using Best-First Algorithm. The only heuristic function I have been able to come up with is explained below: 1. Select an empty cell. 1a. If there are no empty cells and there is a solution return solution. Else return No. 2. Find all possible values it can hold. %% It can't take values currently assigned to cells on the same line/column/box. 3. Set to all those values a heuristic number starting from 1. 4. Pick the value whose heuristic number is the lowest && you haven't checked yet. 4a. If there are no more values return no. 5. If a solution is not found: GoTo 1. Else Return Solution. // I am sorry for errors in this "pseudo code." If you want any clarification let me know. So am I doing this right or is there any other way around and mine is false? Thanks in advance.

  • How to determine the data type of a CvMat

    - by Chris
    When using the CvMat type, the type of data is crucial to keeping your program running. For example, depending on whether your data is type float or unsigned char, you would choose one of these two commands: cvmGet(mat, row, col); cvGetReal2D(mat, row, col); Is there a universal approach to this? If the wrong data type matrix is passed to these calls, they crash at runtime. This is becoming an issue, since a function I have defined is getting passed several different types of matrices. How do you determine the data type of a matrix so you can always access its data? I tried using the "type()" function as such. CvMat* tmp_ptr = cvCreateMat(t_height,t_width,CV_8U); std::cout << "type = " << tmp_ptr->type() << std::endl; This does not compile, saying "term does not evaluate to a function taking 0 arguments". If I remove the brackets after the word type, I get a type of 1111638032 EDIT minimal application that reproduces this... int main( int argc, char** argv ) { CvMat *tmp2 = cvCreateMat(10,10, CV_32FC1); std::cout << "tmp2 type = " << tmp2->type << " and CV_32FC1 = " << CV_32FC1 << " and " << (tmp2->type == CV_32FC1) << std::endl; } Output: tmp2 type = 1111638021 and CV_32FC1 = 5 and 0

  • How to emulate "-lib foo.jar" from _within_ build.xml

    - by Thorbjørn Ravn Andersen
    By specifying "-lib foo.jar" to ant I get the behaviour that the classes in foo.jar is added to the ant classloader and are available for various tasks taking a class name argument. I'd like to be able to specify the same behaviour but only from inside build.xml (so we can do this on a vanilla ant). For taskdefs we have functioning code looking like: <taskdef resource="net/sf/antcontrib/antlib.xml" description="for/foreach tasks"> <classpath> <pathelement location="${active.workspace}/ant-contrib-1.X/lib/ant-contrib.jar" /> </classpath> </taskdef> where the definition is completely provided from the ant-contrib.jar listed. What is the equivalent mechanism for the "global" ant classpath? (I have thought out that this is the way to get <javac> use ecj-3.5.jar to compile with on a JRE - http://stackoverflow.com/questions/2364006/specifying-the-eclipse-compiler-completely-from-within-build-xml - in a way compatible with ant 1.7. Better suggestions are welcome :) EDIT: It appears that the about-to-be-released version 1.0 of ant4eclipse includes ecj. This does not answer the question, but may solve my basic problem.

  • shared memory STL maps

    - by user306963
    Hello, I am writing an Apache module in C++. I need to store the common data that all childs need to read as a portion of shared memory. Structure is kind of map of vectors, so I want to use STL map and vectors for it. I have written a shared allocator and a shared manager for the purpose, they work fine for vectors but not for maps, below is the example: typedef vector<CustomersData, SharedAllocator<CustomersData> > CustomerVector; CustomerVector spData; //this one works fine typedef SharedAllocator< pair< const int, CustomerVector > > PairAllocator; typedef map< int, CustomerVector, less<int>, PairAllocator > SharedMap; SharedMap spIndex; //this one doesn't work I get compile time errors when I try to use the second object (spIndex), which are someting like: ../SpatialIndex.h:97: error: '((SpatialIndex*)this)-SpatialIndex::spIndex' does not have class type It looks like the compiler cannot determine a type for SharedMap template type, which is strange in my opinion, it seems to me that all the template parameters have been specified. Can you help? Thanks Benvenuto

  • What's correct way to remove a boost::shared_ptr from a list?

    - by Catskul
    I have a std::list of boost::shared_ptr<T> and I want to remove an item from it but I only have a pointer of type T* which matches one of the items in the list. However I cant use myList.remove( tPtr ) I'm guessing because shared_ptr does not implement == for its template argument type. My immediate thought was to try myList.remove( shared_ptr<T>(tPtr) ) which is syntactically correct but it will crash from a double delete since the temporary shared_ptr has a separate use_count. std::list< boost::shared_ptr<T> > myList; T* tThisPtr = new T(); // This is wrong; only done for example code. // stand-in for actual code in T using // T's actual "this" pointer from within T { boost::shared_ptr<T> toAdd( tThisPtr ); // typically would be new T() myList.push_back( toAdd ); } { //T has pointer to myList so that upon a certain action, // it will remove itself romt the list //myList.remove( tThisPtr); //doesn't compile myList.remove( boost::shared_ptr<T>(tThisPtr) ); // compiles, but causes // double delete } The only options I see remaining are to use std::find with a custom compare, or to loop through the list brute force and find it myself, but it seems there should be a better way. Am I missing something obvious, or is this just too non-standard a use to be doing a remove the clean/normal way?

  • Creating spotlight in OpenGL scene

    - by Victor Oliveira
    Im studying OpenGL and trying to create a spot light at my application. The code that Im using for my #vertex-shader is below: #:vertex-shader #{ #version 150 core in vec3 in_pos; in vec2 in_tc; out vec2 tc; glLightf(GL_LIGHT0, GL_SPOT_CUTOFF, 20.0f); GLfloat spot_direction[] = { -1.0, -1.0, 0.0 }; glLightfv(GL_LIGHT0, GL_SPOT_DIRECTION, spot_direction); glEnable(GL_LIGHT0); void main() { vec4 pos= vec4(vec3(1.0)*in_pos - vec3(1.0), 1.0); pos.z=0.0; gl_Position = pos; tc = in_tc; } } The thing is, everytime Im trying to run the code an Error that says: Type: other, Source: api, ID: 131169, Severity: low Message: Framebuffer detailed info: The driver allocated storage for renderbuffer 1. len = 157, written = 0 failed to compile vertex shader of deferred: directional info log for shader deferred: directional vertex info log for shader deferred: directional: ERROR: Unbound variable: when Specifications: Renderer: GeForce GTX 580/PCIe/SSE2 Version: 3.3.0 NVIDIA 319.17 GLSL: 3.30 NVIDIA via Cg compiler Status: Using GLEW 1.9.0 1024 x 768 OS: Linux debian I guess to create this spotlight is pretty much simple, but since Im really new to OpenGL I dont have a clue how to do it until now, even reading sources like: http://www.glprogramming.com/red/chapter05.html#name3 Read also in some place that light spots can get really hard to understand, but I cant avoid this step right now since Im following my lecture schedule. Could anybody help me?

  • What is default javac source mode (assert as identifier compilation)?

    - by waste
    According to Orcale's Java7 assert guide: source mode 1.3 (default) — the compiler accepts programs that use assert as an identifier, but issues warnings. In this mode, programs are not permitted to use the assert statement. source mode 1.4 — the compiler generates an error message if the program uses assert as an identifier. In this mode, programs are permitted to use the assert statement. I wrote such class: package mm; public class ClassTest { public static void main(String[] arg) { int assert = 1; System.out.println(assert); } } It should compile fine if Oracle's info right (1.3 is default source mode). But I got errors like this: $ javac -version javac 1.7.0_04 $ javac -d bin src/mm/* src\mm\ClassTest.java:5: error: as of release 1.4, 'assert' is a keyword, and may not be used as an identifier int assert = 1; ^ (use -source 1.3 or lower to use 'assert' as an identifier) src\mm\ClassTest.java:6: error: as of release 1.4, 'assert' is a keyword, and may not be used as an identifier System.out.println(assert); ^ (use -source 1.3 or lower to use 'assert' as an identifier) 2 errors I added manually -source 1.3 and it issued warnings but compiled fine. It seems that Oracle's information is wrong and 1.3 is not default source mode. Which one is it then?

  • Is there a disassembler + debugger for java (ala OllyDbg / SoftICE for assembler)?

    - by Ran Biron
    Is there a utility similar to OllyDbg / SoftICE for java? I.e. execute class (from jar / with class path) and, without source code, show the disassembly of the intermediate code with ability to step through / step over / search for references / edit specific intermediate code in memory / apply edit to file... If not, is it even possible to write something like this (assuming we're willing to live without hotspot for the debug duration)? Edit: I'm not talking about JAD or JD or Cavaj. These are fine decompilers, but I don't want a decompiler for several reasons, most notable is that their output is incorrect (at best, sometimes just plain wrong). I'm not looking for a magical "compiled bytes to java code" - I want to see the actual bytes that are about to be executed. Also, I'd like the ability to change those bytes (just like in an assembly debugger) and, hopefully, write the changed part back to the class file. Edit2: I know javap exists - but it does only one way (and without any sort of analysis). Example (code taken from the vmspec documentation): From java code, we use "javac" to compile this: void setIt(int value) { i = value; } int getIt() { return i; } to a java .class file. Using javap -c I can get this output: Method void setIt(int) 0 aload_0 1 iload_1 2 putfield #4 5 return Method int getIt() 0 aload_0 1 getfield #4 4 ireturn This is OK for the disassembly part (not really good without analysis - "field #4 is Example.i"), but I can't find the two other "tools": A debugger that goes over the instructions themselves (with stack, memory dumps, etc), allowing me to examine the actual code and environment. A way to reverse the process - edit the disassembled code and recreate the .class file (with the edited code).

  • Autocompleting \cite{} with emacs + auctex gives "cite: no such database entry"

    - by Alejandro Weinstein
    Hi: I am running Emacs 23.1.1 and AucTeX 11.85 in an Ubuntu 8.10 machine. After opening a tex file, the first time I try to use the autocompletion of the \cite{} command, I get "cite: info not available, use `C-c &' to get it." in the minibuffer. After doing the 'C-c &', I get "byte-code: No BibTeX entry with citation key". Subsequent calls to \cite gives me the message "cite: no such database entry" . I have a \bibliography{library} in my tex file, and the \cite{} entries that I did manually work as expected. I have the following in my .emacs (require 'reftex) (setq-default TeX-master nil) (add-hook 'LaTeX-mode-hook 'TeX-PDF-mode) ;turn on pdf-mode. AUCTeX ;will call pdflatex to ;compile instead of latex. (add-hook 'LaTeX-mode-hook 'LaTeX-math-mode) ;turn on math-mode by ;default (add-hook 'LaTeX-mode-hook 'reftex-mode) ;turn on REFTeX mode by ;default (add-hook 'LaTeX-mode-hook 'flyspell-mode) ;turn on flyspell mode by ;default (setq reftex-plug-into-AUCTeX t) (setq TeX-auto-save t) (setq TeX-save-query nil) (setq TeX-parse-self t) (setq-default TeX-master nil) I also tried the suggestions in http://stackoverflow.com/questions/2699017/suggestion-for-cite-in-emacs-with-auctex, but it didn't work either.

  • iPhone static library Clang/LLVM error: non_lazy_symbol_pointers

    - by Bekenn
    After several hours of experimentation, I've managed to reduce the problem to the following example (C++): extern "C" void foo(); struct test { ~test() { } }; void doTest() { test t; // 1 foo(); // 2 } This is being compiled for iOS devices in XCode 4.2, using the provided Clang compiler (Apple LLVM compiler 3.0) and the iOS 5.0 SDK. The project is configured as a Cocoa Touch Static Library, and "Enable Linking With Shared Libraries" is set to No because I'm building an AIR native extension. The function foo is defined in another external library. (In my actual project, this would be any of the C API functions defined by Adobe for use in AIR native extensions.) When attempting to compile this code, I get back the error: FATAL:incompatible feature used: section type non_lazy_symbol_pointers (must specify "-dynamic" to be used) clang: error: assembler command failed with exit code 1 (use -v to see invocation) The error goes away if I comment out either of the lines marked 1 or 2 above, or if I change the build setting "Enable Linking With Shared Libraries" to Yes. (However, if I change the build setting, then I get multiple ld warning: unexpected srelocation type 9 warnings when linking the library into the final project, and the application crashes when running on the device.) The build error also goes away if I remove the destructor from test. So: Is this a bug in Clang? Am I missing some all-important and undocumented build setting? The interaction between an externally-provided function and a struct with a destructor is very peculiar, to say the least.
