configure.in: AM_DISABLE_SHARED doesn't change my Makefile

- by t2k32316

I'm extremely new to using Makefiles and autoconf. I'm using the Camellia image library and trying to statically link my code against their libraries. When I run "make" on the Camellia image library, I get libCamellia.a, .so, .la, and .so.0.0.0 files inside my /usr/local/lib directory. This is the command I use to compile my code with their libraries: gcc -L/usr/local/lib -lCamellia -o myprogram myprogram.c This works fine, but when I try to statically link, this is what I get: gcc -static -L/usr/local/lib -lCamellia -o myprogram myprogram.c /tmp/cck0pw70.o: In function `main': myprogram.c:(.text+0x23): undefined reference to `camLoadPGM' myprogram.c:(.text+0x55): undefined reference to `camAllocateImage' myprogram.c:(.text+0x97): undefined reference to `camZoom2x' myprogram.c:(.text+0x104): undefined reference to `camSavePGM' collect2: ld returned 1 exit status I want to statically link because I'm trying to modify the Camellia source code and I want to compare my version against theirs. So after some googling, I tried adding AM_DISABLE_SHARED into the configure.in file. But after running ./configure, I still get the exact same Makefile. After I "make install", I still get the same results above. What is an easy way to get two versions of my code, one with the original Camellia source code compiled and one with my modified version? I think static libraries should work. There is an easy way to get static libraries working or are there other simple solutions to my problem? I just don't want to re-"make" and re-"make install" everytime I want to compare my version against the original.

Visual C++ Testing problem

- by JamesMCCullum

Hi there I have installed VisualAssert and cFix. I have been using Visual Studio C++ and programming in CLI/C++.

How can I stop SharePoint from appending <mso:CustomDocumentProperties> to my output

- by tath.am

I'm trying to hack together an extra feature on top of a POC (smoke and mirrors demo). The POC is on SPS 2007 and I need to integrate with another system. To facilitate part of this, I need to provide a JSONP endpoint. I want this URL: http://sharepoint:2024/Pages/SomeExternalSystem/Payload.aspx?callback=abc To return this: abc({ sampleField1: "sampleData1", sampleField2: 234.56 }); It's all smoke and mirrors anyway, so I uploaded this file to SharePoint: <%@ Page ContentType="text/javascript" Language="C#" %> <%= Request.QueryString["callback"] %>({ sampleField1: "sampleData1", sampleField2: 234.56 }); (And added a page parser rule to allow it to compile the code blocks.) No matter what I seem to do, SharePoint emits this instead: abc({ sampleField1: "sampleData1", sampleField2: 234.56 }); <html xmlns:mso="urn:schemas-microsoft-com:office:office" xmlns:msdt="uuid:C2F41010-65B3-11d1-A29F-00AA00C14882"><head>  </head> It's proving hard to Google for.

how to implement intel's tbb::blocked_range2d in C++

- by Hristo

I'm trying to parallelize nested for loops with parellel_for() and the blocked_range2d from Intel's TBB using C++. The for loops look like this: for(int i = 0; i < N; ++i) { for(int j = 0; j < E[i]; ++j) { for(int k = 0; k < T; ++k) { score[k] += delta(i, trRating[k][i], exRating[j][i]); } } } ... and I am trying to do the following: class LoopBody { private: int *myscore; public: LoopBody(int *score) { myscore = score; } void operator()(const blocked_range2d<int> &r) const { for(int i = r.rows().begin(); i != r.rows().end(); ++i); for(int j = 0; j < E[i]; ++j) { for(int k = r.cols().begin(); k != r.cols().end(); ++k) { myscore[k] += foo(...); // uses i,j,k to look up indices in arrays } } } } }; void computeScores(int score[]) { parallel_for(blocked_range2d<int>(0, N, 0, T), LoopBody(score)); } ... but I am getting the following compile errors: error: identifier "i" is undefined for(int j = 0; j < E[i]; ++j) { ^ error: expected an identifier }; ^ I'm not really sure if I am doing this the right way, but any advice is appreciated. Also, this is my first time using Intel's TBB so I really don't know anything about it. Any ideas how make this work? Thanks, Hristo

Compiling external C++ library (Octave) for iPhone (Fortran compiler missing?)

- by Shaggy Frog

A friend of mine asked me if it would be possible to port the Octave project to the iPhone. I haven't compiled an external package for an iPhone project before, so I downloaded the source code, and then used some scripts found on a couple of different Web sites (one, two) to try and build the libraries. However, when I try either of these scripts (which are nearly identical), they eventually die during the configure phase with the following error output: [...snip checks...] checking whether we are using the GNU Fortran 77 compiler... no checking whether accepts -g... no checking how to get verbose linking output from ... configure: WARNING: compilation failed checking for Fortran 77 libraries of ... rm: conftest.dSYM: is a directory checking for dummy main to link with Fortran 77 libraries... rm: conftest.dSYM: is a directory none checking for Fortran 77 name-mangling scheme... configure: error: cannot compile a simple Fortran program See `config.log' for more details. Is the problem that the iPhone SDK/Xcode doesn't include a Fortran cross-compiler, or am I doing something wrong?

How yo play rington/alarm sound in Android

- by Federico

I have been looking everywhere how to play a $#@&! rington/alarm sound in android. I press a button and I want to play a rington/alarm sound. I could not find a easy, strsight forward sample... YES! I already looked at Alarm clock source code... but it is not straight forward and I cannot compile it neither. I cannot make this work: Uri alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM); mMediaPlayer = new MediaPlayer(); mMediaPlayer.setDataSource(this, alert); final AudioManager audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE); if (audioManager.getStreamVolume(AudioManager.STREAM_ALARM) != 0) { player.setAudioStreamType(AudioManager.STREAM_ALARM); player.setLooping(true); player.prepare(); player.start(); } I get this error 04-11 17:15:27.638: ERROR/MediaPlayerService(30): Couldn't open fd for content://settings/system/ringtone So.. please if somebody knows how to play a default rington/alarm let me know. I prefer not to upload any file. Just play a default rington. Thanks, Federico

Repackaging Jasper-Reports into an application specific OSGi bundle, legal or not?

- by Chris

Hi, I wanted to ask (probably a silly) question regarding the packaging of existing open-source components as OSGi bundles (more specifically Jasper Reports). I have an application that I am converting from a monolithic jar-hell type architecture to something more moduler and OSGi is my weapon of choice. There are various modules I have in mind but one of the modules is a reporting module. My own reporting module will be a jar file containing my code that should reference a Jasper Reports bundle. Trouble is, Jasper reports depends on far far too many libraries and is quite monolithic in its own right. I therefore wish to build my own Jasper Reports bundle but this is where I start getting confused about the legality of repackaging. I don't plan to re-compile but I do plan to re-bundle removing known items that I do not require. Can anyone offer advice on whether I am permitted to repackage (not recompile or extend) open-source libraries into OSGi bundles without falling foul of 'derivative works' clause of LGPL? I noticed that Groovy seems to offer some monolithic jars that include all dependancies and actually goes so far as to re-arrange the packages of its dependancies so that there are no namespace conflicts. This seems to me to be a violation of the license but if anyone can reassure me that this is legal then I would feel safer about my less intrusive custom-bundling of Jasper reports. Thanks for your time, Chris

Infinite loop in regex in java

- by carpediem

Hello, My purpose is to match this kind of different urls: url.com my.url.com my.extended.url.com a.super.extended.url.com and so on... So, I decided to build the regex to have a letter or a number at start and end of the url, and to have a infinite number of "subdomains" with alphanumeric characters and a dot. For example, in "my.extended.url.com", "m" from "my" is the first class of the regex, "m" from "com" is the last class of the regex, and "y.", "extended." and "url." are the second class of the regex. Using the pattern and subject in the code below, I want the find method to return me a false because this url must not match, but it uses 100% of CPU and seems to stay in an infinite loop. String subject = "www.association-belgo-palestinienne-be"; Pattern pattern = Pattern.compile("^[A-Za-z0-9]\\.?([A-Za-z0-9_-]+\\.?)*[A-Za-z0-9]\\.[A-Za-z]{2,6}"); Matcher m = pattern.matcher(subject); System.out.println(" Start"); boolean hasFind = m.find(); System.out.println(" Finish : " + hasFind); Which only prints: Start I can't reproduce the problem using regex testers. Is it normal ? Is the problem coming from my regex ? Could it be due to my Java version (1.6.0_22-b04 / JVM 64 bit 17.1-b03) ? Thanks in advance for helping.

Exporting static data in a DLL

- by Gayan

I have a DLL which contains a class with static members. I use __declspec(dllexport) in order to make use of this class's methods. But when I link it to another project and try to compile it, I get "unresolved external symbol" errors for the static data. e.g. In DLL, Test.h class __declspec(dllexport) Test{ protected: static int d; public: static void m(){} } In DLL, Test.cpp #include "Test.h" int Test::d; In the application which uses Test, I call m(). I also tried using __declspec(dllexport) for each method separately but I still get the same link errors for the static members. If I check the DLL (the .lib) using dumpbin, I could see that the symbols have been exported. For instance, the app gives the following error at link time: 1>Main.obj : error LNK2001: unresolved external symbol "protected: static int CalcEngine::i_MatrixRow" (?i_MatrixRow@CalcEngine@@1HA) But the dumpbin of the .lib contains: Version : 0 Machine : 14C (x86) TimeDateStamp: 4BA3611A Fri Mar 19 17:03:46 2010 SizeOfData : 0000002C DLL name : CalcEngine.dll Symbol name : ?i_MatrixRow@CalcEngine@@1HA (protected: static int CalcEngine::i_MatrixRow) Type : data Name type : name Hint : 31 Name : ?i_MatrixRow@CalcEngine@@1HA I can't figure out how to solve this. What am I doing wrong? How can I get over these errors? P.S. The code was originally developed for Linux and the .so/binary combination works without a problem

Why is Swing Parser's handleText not handling nested tags?

- by Jim P

I need to transform some HTML text that has nested tags to decorate 'matches' with a css attribute to highlight it (like firefox search). I can't just do a simple replace (think if user searched for "img" for example), so I'm trying to just do the replace within the body text (not on tag attributes). I have a pretty straightforward HTML parser that I think should do this: final Pattern pat = Pattern.compile(srch, Pattern.CASE_INSENSITIVE); Matcher m = pat.matcher(output); if (m.find()) { final StringBuffer ret = new StringBuffer(output.length()+100); lastPos=0; try { new ParserDelegator().parse(new StringReader(output.toString()), new HTMLEditorKit.ParserCallback () { public void handleText(char[] data, int pos) { ret.append(output.subSequence(lastPos, pos)); Matcher m = pat.matcher(new String(data)); ret.append(m.replaceAll("<span class=\"search\">$0</span>")); lastPos=pos+data.length; } }, false); ret.append(output.subSequence(lastPos, output.length())); return ret; } catch (Exception e) { return output; } } return output; My problem is, when I debug this, the handleText is getting called with text that includes tags! It's like it's only going one level deep. Anyone know why? Is there some simple thing I need to do to HTMLParser (haven't used it much) to enable 'proper' behavior of nested tags? PS - I figured it out myself - see answer below. Short answer is, it works fine if you pass it HTML, not pre-escaped HTML. Doh! Hope this helps someone else. <span>example with <a href="#">nested</a> <p>more nesting</p> </span>

Can't operator == be applied to generic types in C#?

- by Hosam Aly

According to the documentation of the == operator in MSDN, For predefined value types, the equality operator (==) returns true if the values of its operands are equal, false otherwise. For reference types other than string, == returns true if its two operands refer to the same object. For the string type, == compares the values of the strings. User-defined value types can overload the == operator (see operator). So can user-defined reference types, although by default == behaves as described above for both predefined and user-defined reference types. So why does this code snippet fail to compile? void Compare<T>(T x, T y) { return x == y; } I get the error Operator '==' cannot be applied to operands of type 'T' and 'T'. I wonder why, since as far as I understand the == operator is predefined for all types? Edit: Thanks everybody. I didn't notice at first that the statement was about reference types only. I also thought that bit-by-bit comparison is provided for all value types, which I now know is not correct. But, in case I'm using a reference type, would the the == operator use the predefined reference comparison, or would it use the overloaded version of the operator if a type defined one? Edit 2: Through trial and error, we learned that the == operator will use the predefined reference comparison when using an unrestricted generic type. Actually, the compiler will use the best method it can find for the restricted type argument, but will look no further. For example, the code below will always print true, even when Test.test<B>(new B(), new B()) is called: class A { public static bool operator==(A x, A y) { return true; } } class B : A { public static bool operator==(B x, B y) { return false; } } class Test { void test<T>(T a, T b) where T : A { Console.WriteLine(a == b); } }

string parsing to double fails in C++ (Xcode problem?)

- by helixed

Here's a fun one I've been trying to figure out. I have the following program: #include <iostream> #include <string> #include <sstream> using namespace std; int main(int argc, char *argv[]) { string s("5"); istringstream stream(s); double theValue; stream >> theValue; cout << theValue << endl; cout << stream.fail(); } The output is: 0 1 I don't understand why this is failing. Could somebody please tell me what I'm doing wrong? Thanks, helixed EDIT: Okay, sorry to turn this into a double post, but this looks like a problem specific to Xcode. If I compile this in g++, the code works without a problem. Does anybody have an idea why this is happening in Xcode, and how I could possibly fix it? Thanks again, helixed

Yacc and Lex inclusion confusion

- by thejohnmeister

I am wondering how to correctly compile a program with a Makefile that has calls to yyparse in it? This is what I do: I have a Makefile that compiles all my regular files and they have no connections to y.tab.c or lex.yy.c (Am I supposed to have them?) I do this on top of my code: #include "y.tab.c" #include "lex.yy.c" #include "y.tab.h" This is what happens when I try to make the program: When I just type in "make", it gives me many warnings. Some of the examples are shown below. In function yywrap': /src/parser.y:12: multiple definition ofyywrap' server.o :/src/parser.y:12: first defined here utils.o: In function yyparse': /src/y.tab.c:1175: multiple definition ofyyparse' server.o:/src/y.tab.c:1175: first defined here utils.o I get many different errors referring to different yy_* files. I have compiled successfully with multiple calls to yyparse in the past, but this time seems to be different. It seems an awful lot like an inclusion problem somewhere but I can't tell what it is. All my header files have ifndef conditions, as well. Thanks for your help!

Write a compiler for a language that looks ahead and multiple files?

- by acidzombie24

In my language I can use a class variable in my method when the definition appears below the method. It can also call methods below my method and etc. There are no 'headers'. Take this C# example. class A { public void callMethods() { print(); B b; b.notYetSeen(); public void print() { Console.Write("v = {0}", v); } int v=9; } class B { public void notYetSeen() { Console.Write("notYetSeen()\n"); } } How should I compile that? what i was thinking is: pass1: convert everything to an AST pass2: go through all classes and build a list of define classes/variable/etc pass3: go through code and check if there's any errors such as undefined variable, wrong use etc and create my output But it seems like for this to work I have to do pass 1 and 2 for ALL files before doing pass3. Also it feels like a lot of work to do until I find a syntax error (other than the obvious that can be done at parse time such as forgetting to close a brace or writing 0xLETTERS instead of a hex value). My gut says there is some other way. Note: I am using bison/flex to generate my compiler.

JVM/CLR Source-compatible Language Options

- by Nathan Voxland

I have an open source Java database migration tool (http://www.liquibase.org) which I am considering porting to .Net. The majority of the tool (at least from a complexity side) is around logic like "if you are adding a primary key and the database is Oracle use this SQL. If database is MySQL use this SQL. If the primary key is named and the database is Postgres use this SQL". I could fork the Java codebase and covert it (manually and/or automatically), but as updates and bug fixes to the above logic come in I do not want to have to apply it to both versions. What I would like to do is move all that logic into a form that can be compiled and used by both Java and .Net versions naively. The code I am looking to convert does not contain any advanced library usage (JDBC, System.out, etc) that would vary significantly from Java to .Net, so I don't think that will be an issue (at worst it can be designed around). So what I am looking for is: A language in which I can code common parts of my app in and compile it into classes usable by the "standard" languages on the target platform Does not add any runtime requirements to the system Nothing so strange that it scares away potential contributors I know Python and Ruby both have implementations on for the JVM and CLR. How well do they fit my requirements? Has anyone been successful (or unsuccesful) using this technique for cross-platform applications? Are there any gotcha's I need to worry about?

Generating equals / hashcode / toString using annotation

- by Bruno Bieth

I believe I read somewhere people generating equals / hashcode / toString methods during compile time (using APT) by identifying which fields should be part of the hash / equality test. I couldn't find anything like that on the web (I might have dreamed it ?) ... That could be done like that : public class Person { @Id @GeneratedValue private Integer id; @Identity private String firstName, lastName; @Identity private Date dateOfBirth; //... } For an entity (so we want to exlude some fields, like the id). Or like a scala case class i.e a value object : @ValueObject public class Color { private int red, green, blue; } Not only the file becomes more readable and easier to write, but it also helps ensuring that all the attributes are part of the equals / hashcode (in case you add another attribute later on, without updating the methods accordingly). I heard APT isn't very well supported in IDE but I wouldn't see that as a major issue. After all, tests are mainly run by continuous integration servers. Any idea if this has been done already and if not why ? Thanks

Why can't nvcc find my Visual C++ installation?

- by Jack Lloyd

I'm running Windows 7 Pro x64 on a Core i5 with a NVIDIA 3100m, which is CUDA compatible. I've tried installing both the 32-bit and 64-bit CUDA toolkits from NVIDIA, unfortunately from with either of them I cannot compile anything; nvcc says "cannot find a supported cl version. Only MSVC 8.0 and MSVC 9.0 are supported". I have the x86 and x86-64 compilers installed via the Windows 7 SDK (compiler version 15.00.30729.01 for both arches). Both compilers are operating correctly; I've built and tested C and C++ code using them. I've tried running nvcc from command shells set up for both 32 bit and 64 bit compilation, and using the -ccbin command line option to nvcc to point it at the Visual C++ install directory. What is the right way of handling this setup? Is there some way I make nvcc be more verbose about what is going on? The -v flag isn't terrible helpful. Ideally some way to make it show what it is finding versus what it's expecting to find. Will this work better if I install Visual C++ Express instead? Or is only a commercial version of VC++ supported for use with CUDA?

I have 3 tables: Pendants PendantAccessories PartsData Basically #1 and 2 are used for product selection, so #1 has a "Number of Buttons" property and other options. #2 has fields like "Cable Type" etc. The third table contains property information for all of our parts, such as what plant it's manufactured in, it's weight etc. What I'm trying to do is set up an association between #1 and #3 and also between #2 and #3. The PK in all 3 tables is the PartNumber. I set it up between #2 and 3 by going into Mapping Details and adding a Maps to PartsData and mapping the columns. Everything worked good. I then tried the same thing between #1 and 3. However, now when I compile I get "Error 3033: Problem in Mapping Fragment starting at line 713: EntitySets 'pendants' and 'pendantAccessories' are both mapped to the table 'PartsData'. Their Primary Keys may collide." Does anyone know what I'm doing wrong here?

Is there an easy way to get the Scala REPL to reload a class or package?

- by Rex Kerr

I almost always have a Scala REPL session or two open, which makes it very easy to give Java or Scala classes a quick test. But if I change a class and recompile it, the REPL continues with the old one loaded. Is there a way to get it to reload the class, rather than having to restart the REPL? Just to give a concrete example, suppose we have the file Test.scala: object Test { def hello = "Hello World" } We compile it and start the REPL: ~/pkg/scala-2.8.0.Beta1-prerelease$ bin/scala Welcome to Scala version 2.8.0.Beta1-prerelease (Java HotSpot(TM) Server VM, Java 1.6.0_16). Type in expressions to have them evaluated. Type :help for more information. scala> Test.hello res0: java.lang.String = Hello World Then we change the source file to object Test { def hello = "Hello World" def goodbye = "Goodbye, Cruel World" } but we can't use it: scala> Test.goodbye <console>:5: error: value goodbye is not a member of object Test Test.goodbye ^ scala> import Test; <console>:1: error: '.' expected but ';' found. import Test;

Error doing an MSBuild on a CLR Storedprocedure project on Build Server

- by CraftyFella

Hi, When building a CLR Storedprocedure Project using MSBuild on our build server (Team City) we're getting the following error: error MSB4019: The imported project "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\SqlServer.targets" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk I've checked to see if the file exists on disk and sure enough it doesn't. I've checked on my own machine and it does exist. I don't really want to start copying over files manually to the build server. Here's the line from the csproj file which is being imported to the proj file: <Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" /> <Import Project="$(MSBuildToolsPath)\SqlServer.targets" /> Here's the line from the proj file which is begin run by our Team City Server: <Import Project="..\$(ProjectName).csproj"/> My question is really: Where does this file comes from? Is it part of the Visual Studio install for example.. Or is there some re-distribution package somewhere to allow me to compile this project on our build server? Thanks BTW.. if i just copy the file onto the Build server it does actually work. Dave
