  • How do I know if a particular build has a particular version control change in it?

    - by carleeto
    Let's say I have a build. I need to know if a particular changelist/commit is present in that build. How would I solve this problem? I can think of a couple of possible approaches: 1) Add the changelist number into the binary so that I can look somewhere in the GUI and know what the changelist number is. I can then use this information to determine if the change I'm interested in is within that build. 2) Tag version control using some string that uniquely identifies that build. What unique string would I use? Is either of these two better? Are there any other better approaches? The solution would have to work for both Mac and Windows builds.

  • Binary serialization/de-serialization in C++ and C#

    - by 6pack kid
    Hello. I am working on a distributed application which has two components. One is written in standard C++ (not managed C++) and the other one is written in C#. Both are communicating via a message bus. I have a situation in which I need to pass objects from C++ to C# application and for this I need to serialize those objects in C++ and de-serialize them in C# (something like marshaling/un-marshaling in .NET). I need to perform this serialization in binary and not in XML (due to performance reasons). I have used Boost.Serialization to do this when both ends were implemented in C++ but now that I have a .NET application on one end, Boost.Serialization is not a viable solution. I am looking for a solution that allows me to perform (de)serialization across C++ and .NET boundary i.e., cross platform binary serialization. I know I can implement the (de)serialization code in a C++ dll and use P/Invoke in the .NET application, but I want to keep that as a last resort. Also, I want to know if I use some standard like gzip, will that be efficient? Are there any other alternatives to gzip? What are the pros/cons of them? Thanks

  • Xcode newb -- #include can't find my file

    - by morgancodes
    I'm trying to get a third party audio library (STK) working inside Xcode. Along with the standard .h files, many of the implementation files include a file called SKINI.msg. SKINI.msg is in the same directory as all of the header files. The header files are getting included fine, but the compiler complains that it can't find SKINI.msg. What do I need to do to get Xcode to happily include SKINI.msg? Edit: Here's the contents of SKINI.msg: /*********************************************************/ /* Definition of SKINI Message Types and Special Symbols Synthesis toolKit Instrument Network Interface These symbols should have the form: \c __SK_<name>_ where <name> is the string used in the SKINI stream. by Perry R.

  • C++ meta-splat function

    - by aaa
    hello. Is there an existing function (in boost mpl or fusion) to splat meta-vector to variadic template arguments? for example: splat<vector<T1, T2, ...>, function>::type same as function<T1, T2, ...> my search have not found one, and I do not want to reinvent one if it already exists. edit: after some tinkering, apparently it's next to impossible to accomplish this in general way, as it would require declaring full template template parameter list for all possible cases. only reasonable solution is to use macro: #define splat(name, function) \ template<class T, ...> struct name; \ template<class T> \ struct name<T,typename boost::enable_if_c< \ result_of::size<T>::value == 1>::type> { \ typedef function< \ typename result_of::value_at_c<T,0>::type \ > type; \ }; Oh well. thank you

  • How to handle 'this' pointer in constructor?

    - by Kyle
    I have objects which create other child objects within their constructors, passing 'this' so the child can save a pointer back to its parent. I use boost::shared_ptr extensively in my programming as a safer alternative to std::auto_ptr or raw pointers. So the child would have code such as shared_ptr<Parent>, and boost provides the shared_from_this() method which the parent can give to the child. My problem is that shared_from_this() cannot be used in a constructor, which isn't really a crime because 'this' should not be used in a constructor anyways unless you know what you're doing and don't mind the limitations. Google's C++ Style Guide states that constructors should merely set member variables to their initial values. Any complex initialization should go in an explicit Init() method. This solves the 'this-in-constructor' problem as well as a few others as well. What bothers me is that people using your code now must remember to call Init() every time they construct one of your objects. The only way I can think of to enforce this is by having an assertion that Init() has already been called at the top of every member function, but this is tedious to write and cumbersome to execute. Are there any idioms out there that solve this problem at any step along the way?

  • Is there a way to find out whether a class is a direct base of another class?

    - by user176168
    Hi I'm wondering whether there is a way to find out whether a class is a direct base of another class i.e. in boost type trait terms a is_direct_base_of function. As far as I can see boost doesn't see to support this kind of functionality which leads me to think that its impossible with the current C++ standard. The reason I want it is to do some validation checking on two macro's that are used for a reflection system to specify that one class is derived from another e.g. header.h: #define BASE A #define DERIVED B class A {}; class B : public A { #include <rtti.h> }; rtti.h: // I want to check that the two macro's are correct with a compile time assert Rtti<BASE, DERIVED> m_rtti; Although the macro's seem unnecessary in this simple example in my real world scenario rtti.h is a lot more complex. One possible avenue would be to compare the size of the this pointer with the size of a this pointer cast to the base type and some how trying to figure out whether its the size of the base class itself away or something (yeah your right I don't know how that would work either! lol)

  • A generic C++ library that provides QtConcurrent functionality?

    - by Lucas
    QtConcurrent is awesome. I'll let the Qt docs speak for themselves: QtConcurrent includes functional programming style APIs for parallel list processing, including a MapReduce and FilterReduce implementation for shared-memory (non-distributed) systems, and classes for managing asynchronous computations in GUI applications. For instance, you give QtConcurrent::map() an iterable sequence and a function that accepts items of the type stored in the sequence, and that function is applied to all the items in the collection. This is done in a multi-threaded manner, with a thread pool equal to the number of logical CPU's on the system. There are plenty of other function in QtConcurrent, like filter(), filteredReduced() etc. The standard CompSci map/reduce functions and the like. I'm totally in love with this, but I'm starting work on an OSS project that will not be using the Qt framework. It's a library, and I don't want to force others to depend on such a large framework like Qt. I'm trying to keep external dependencies to a minimum (it's the decent thing to do). I'm looking for a generic C++ framework that provides me with the same/similar high-level primitives that QtConcurrent does. AFAIK boost has nothing like this (I may be wrong though). boost::thread is very low-level compared to what I'm looking for. I know C# has something very similar with their Parallel Extensions so I know this isn't a Qt-only idea. What do you suggest I use?

  • C++ variable to const expression

    - by user1344784
    template <typename Real> class A{ }; template <typename Real> class B{ }; //... a few dozen more similar template classes class Computer{ public slots: void setFrom(int from){ from_ = from; } void setTo(int to){ to_ = to; } private: template <int F, int T> void compute(){ using boost::fusion::vector; using boost::fusion::at_c; vector<A<float>, B<float>, ...> v; at_c<from_>(v).operator()(at_c<to_>(v)); //error; needs to be const-expression. }; This question isn't about Qt, but there is a line of Qt code in my example. The setFrom() and setTo() are functions that are called based on user selection via the GUI widget. The root of my problem is that 'from' and 'to' are variables. In my compute member function I need to pick a type (A, B, etc.) based on the values of 'from' and 'to'. The only way I know how to do what I need to do is to use switch statements, but that's extremely tedious in my case and I would like to avoid. Is there anyway to convert the error line to a constant-expression?

  • template specialization for static member functions; howto?

    - by Rolle
    I am trying to implement a template function with handles void differently using template specialization. The following code gives me an "Explicit specialization in non-namespace scope" in gcc: template <typename T> static T safeGuiCall(boost::function<T ()> _f) { if (_f.empty()) throw GuiException("Function pointer empty"); { ThreadGuard g; T ret = _f(); return ret; } } // template specialization for functions wit no return value template <> static void safeGuiCall<void>(boost::function<void ()> _f) { if (_f.empty()) throw GuiException("Function pointer empty"); { ThreadGuard g; _f(); } } I have tried moving it out of the class (the class is not templated) and into the namespace but then I get the error "Explicit specialization cannot have a storage class". I have read many discussions about this, but people don't seem to agree how to specialize function templates. Any ideas?

  • Confused about std::runtime_error vs. std::logic_error

    - by David Gladfelter
    I recently saw that the boost program_options library throws a logic_error if the command-line input was un-parsable. That challenged my assumptions about logic_error vs. runtime_error. I assumed that logic errors (logic_error and its derived classes) were problems that resulted from internal failures to adhere to program invariants, often in the form of illegal arguments to internal API's. In that sense they are largely equivalent to ASSERT's, but meant to be used in released code (unlike ASSERT's which are not usually compiled into released code.) They are useful in situations where it is infeasible to integrate separate software components in debug/test builds or the consequences of a failure are such that it is important to give runtime feedback about the invalid invariant condition to the user. Similarly, I thought that runtime_errors resulted exclusively from runtime conditions outside of the control of the programmer: I/O errors, invalid user input, etc. However, program_options is obviously heavily (primarily?) used as a means of parsing end-user input, so under my mental model it certainly should throw a runtime_error in the case of bad input. Where am I going wrong? Do you agree with the boost model of exception typing?

  • Is it possible to create ostream object, which outputs to multiple destinations?

    - by fiktor
    In 0-th approximation I have a class class MyClass{ public: ... std::ostream & getOStream(){return f;} private: ofstream f; ... }; Which is used sometimes in the following way: MyClass myclass; myclass.getOStream()<<some<<information<<printed<<here; But now I want to change the class MyClass, so that information will be printed both to f and to std::out, i.e. I want the above line to be equivalent to myclass.f<<some<<information<<printed<<here; std::cout<<some<<information<<printed<<here; I don't know any good way to do that. Do you? Is there any standard solution (for example in stl or in boost)? P.S. I tried to search on this, but it seems that I don't know good keywords. Words multiple, output, ostream, C++, boost seem to be too general.

  • Visual Studio build fails: unable to copy exe-file from obj\debug to bin\debug

    - by Nailuj
    This is a question asked before, both here on Stack Overflow and other places, but none of the suggestions I've found this far has helped me, so I just have to try asking a new question. Scenario: I have a simple Windows Forms application (C#, .NET 4.0, Visual Studio 2010). It has a couple of base forms that most other forms inherit from, it uses Entity Framework (and POCO classes) for database access. Nothing fancy, no multi-threading or anything. Problem: All was fine for a while. Then, all out of the blue, Visual Studio failed to build when I was about to launch the application. I got the warning "Unable to delete file '...bin\Debug\[ProjectName].exe'. Access to the path '...bin\Debug\[ProjectName].exe' is denied." and the error "Unable to copy file 'obj\x86\Debug\[ProjectName].exe' to 'bin\Debug\[ProjectName].exe'. The process cannot access the file 'bin\Debug\[ProjectName].exe' because it is being used by another process." (I get both the warning and the error when running Rebuild, but only the error when running Build - don't think that is relevant?) I understand perfectly fine what the warning and error message says: Visual Studio is obviously trying to overwrite the exe-file while it the same time has a lock on it for some reason. However, this doesn't help me find a solution to the problem... The only thing I've found working is to shut down Visual Studio and start it again. Building and launching then works, untill I make a change in some of the forms, then I have the same problem again and have to restart... Quite frustrating! As I mentioned above, this seems to be a known problem, so there are lots of suggested solutions. I'll just list what I've already tried here, so people know what to skip: Creating a new clean solution and just copy the files from the old solution. Adding the following to the following to the project's pre-build event: if exist "$(TargetPath).locked" del "$(TargetPath).locked"   if not exist "$(TargetPath).locked" if exist "$(TargetPath)" move "$(TargetPath)" "$(TargetPath).locked" Adding the following to the project properties (.csproj file): <GenerateResourceNeverLockTypeAssembliestrue</GenerateResourceNeverLockTypeAssemblies However, none of them worked for me, so you can probably see why I'm starting to get a bit frustrated. I don't know where else to look, so I hope somebody has something to give me! Is this a bug in VS, and if so is there a patch? Or has I done something wrong, do I have a circular reference or similar, and if so how could I find out? Any suggestions are highly appreciated :)

  • flash.display.Loader blocks on load in release build

    - by Anders
    I'm loading a swf-file from my program written in as3 using the flash.display.Loader class. When I'm using the debug build configuration in FlashDevelop everything works fine. But when I'm using the release build configuration the program freezes for around two seconds efter the loader sends the progress events and before sending the complete event. This is my program: package { import flash.display.Loader; import flash.display.Sprite; import flash.events.Event; import flash.events.ProgressEvent; import flash.net.URLRequest; import flash.system.LoaderContext; import flash.system.ApplicationDomain; import flash.text.TextField; public class Main extends Sprite { private var frameCounter:int; private var frameCounterField:TextField = new TextField; private var statusField:TextField = new TextField; function Main():void { if (stage) init(); else addEventListener(Event.ADDED_TO_STAGE, init); } private function init(e:Event = null):void { removeEventListener(Event.ADDED_TO_STAGE, init); addEventListener(Event.ENTER_FRAME, frame); frameCounterField.text = "On frame " + frameCounter.toString(); addChild(frameCounterField); statusField.y = 40; statusField.width = 300; addChild(statusField); var context:LoaderContext = new LoaderContext(false, ApplicationDomain.currentDomain, null); var urlReq:URLRequest = new URLRequest("SomeFile.swf"); var loader:Loader = new Loader(); loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgress); loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete); loader.load(urlReq, context); } private function frame(event:Event):void { frameCounterField.text = "On frame " + (++frameCounter).toString(); } private function onProgress(event:ProgressEvent):void { statusField.appendText("Progress on frame: " + frameCounter.toString() + " Loaded: " + event.bytesLoaded + " / " + event.bytesTotal + "\n"); } private function onComplete(event:Event):void { statusField.appendText("Completed on frame: " + frameCounter.toString() + "\n"); } } } In release I get the following output on the first frame: On frame 1 Progress on frame: 1 Loaded: 0 / 182468 Progress on frame: 1 Loaded: 65536 / 182468 Progress on frame: 1 Loaded: 131072 / 182468 Progress on frame: 1 Loaded: 182468 / 182468 After around two seconds where the program is frozen the line Completed on frame: 2 is added and the 'On frame X' counter starts ticking up. Debug build produces the same output but without the freeze. Not all swf-files I have tried loading triggers the problem. The size of the file doesn't seem to affect anything. I have tried compiling and running on another computer with the same result. What could cause this problem?

  • ASP.net - First build fails with 'Unknown server tag'

    - by Sophia
    I have multiple custom controls used on a ASPX (and C#) page registered from within the page rather than in Web.Config. On the first build (or rebuild), build fails with error messages for wherever I've used the custom controls. Subsequent builds are successful. The error message: Unknown server tag 'prefix:ExampleControl'. What might cause this, and how can I fix it? Register syntax: <%@ Register Src="ControlsFolder/ExampleControl.ascx" TagName="ExampleControl" TagPrefix="prefix" %> <!-- etc --> Usage syntax: <prefix:ExampleControl runat="server" ID="ExampleControl1" /> <!-- etc -->

  • How to build a java applet?

    - by Stefano Borini
    Most of the tutorials around explain how to create a java applet: create a .java file with a class, compile it with javac, put the .class somewhere, add a proper tag in the html. However, I'm not able to find anything about the best practices to build and release a complex applet, made of multiple classes and with additional libraries. How is the build/release process for this case ? What is it needed to go from my java project to the final .jar to put on the web ? I'm working with pure Eclipse, no plugins.

  • Visual Studio 2008 Build question x64 vs x86

    - by Brett
    Hi Everyone, I have written an application on my x64 machine in Visual Stuido 2008. The application will be sent to someone, and I have two questions that I need answers to. What requirements will they need to have installed. I am assuming the .NET 3.5 redistributable. Are there anything else though? (The application does not call any external dependencies). This is my realy question that I can't find the answer to. I have developed and build the application on my x64 machine using the "Any CPU" option (as versus x64 or x86 specifically). Will this run on a 32 bit machine? (I don't have one to test). Or do I need to build it specifically for x86 in order to run it on a 32 bit machine? Many thanks, Brett

  • MSBuild Build Sequence

    - by pm_2
    I got this from here. <ItemGroup> <SolutionToBuild Include="$(SolutionRoot)\path\MySolution.sln /> <SolutionToBuild Include="$(SolutionRoot)\Scribble\scribble.sln" /> <SolutionToBuild Include="$(SolutionRoot)\HelloWorld\HelloWorld.sln" /> <SolutionToBuild Include="$(SolutionRoot)\TestProject1\TestProject1.sln" /> </ItemGroup> It says that the sequence of the build is determined by the order above. So, for example, MySolution would be built before scribble. However, is this safe if scribble is dependant on MySolution? If MySolution and scribble are changed simultaneously, will the build wait for MySolution to be completely compiled before moving to the next project?

  • GWT Post build command in Eclipse

    - by Henrik
    I am starting getting used to Eclipse, but I have much more experience with Visual Studio. In Visual Studio it is possible to run auto commands after the build has finished. Now I am creating a GWT project and several other projects at once in one solution (or workspace) in Eclipse. Some files which are compiled with the GWT project needs to be copied to another location when they have been compiled. I am currently doing this manually and would like to do it automatically. I am not doing it often, since the project works fine in debug mode (...?gwt.codesvr=localhost:9997). But where is the location for executing a post build command for a GWT project in eclipse? Is it possible?
