Mingw winmain error code

lib", it will NOT be called by the C- Runtime directly. With visual C+ + it' s an indicator that you choose the wrong project type ( Win32 instead of console). I don' t know whether that applies to eclipse. If it failed during the build which undefined reference to ` WinMain' would indicate, then there is no executable to execute. Something appears to want the function WinMain and the linker couldn' t find it in any of the supplied object files or libraries. V schreef op: 44: > Over time Sourceforge has become a shady service.

I admit that the linker- message about missing WinMain looks on the first hand a bit irretating, But we have to support ventures using for - mwindows GUI subsystem the function main as entry- point instead of proper WinMain one, so we have a forwarding main( ) to WinMain( ) imlementation in startup- code. This is why it is looking for the windows entry point ' WinMain', rather than the console entry point ' main'. I suggest you create a new project, being careful to select " Console Application", and then copy the source code over from the old project to the new one.

    Code winmain error

    In Code: : Blocks the option to change this is under: Project - > Properties then select the ' Build Type' tab and look for the ' Type' drop- down box. Want to start a project with SDL2 with c+ +, and found this wrapper ( awesome work on it btw), but I found problems when I tried to compile it in a Mingw- w64 environment ( using MSYS2). PyCharm is an IDE I' m quite familiar with, so when ( again) starting with C/ C+ + it was only natural to take a peek at CLion ( nice timing to pushing out the 1. What is supported? 0 supports Windows XP, Windows Vista, Windows 7 and Windows 8. SDL can be built with Visual C+ +, Cygwin, MinGW, and Dev- C+ +. It means you' re building your program as a 16- bit windows executable. WinMain( ) is the traditional start point for windows programs ( rather than main( ) which is standard C) and is that name as adorned when compiling and linking to produce a 16 bit windows program. So right now I can' t run or compile C programs on my laptop. I installed MinGW64 bit.

    But right now I can' t run a code on my eclipse or windows command prompt. These libraries all implement a main( ) function and then a stub WinMain function for Windows only to call that main( ) function. So it is important for mingw to get this right. If you would like to refer to this comment somewhere else in this project, copy and paste the following link:. Either create a new project of the console type and copy your code into it, or use the ' sticky- tape' solution, and change int main( ) to int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) You would also need to navigate to the project' s properties and change the Build Target from GUI application to. So you have no problems with the different bit versions and also reinstalled VS and mingw gcc compiler? Also creating a new project as console application in VS did not work? The WinMain function that is missing from your code is the " main" function that is expected from a GUI Win32 application. If you select " console" application, it should be looking for the " main( ) " function, which I presume you have defined in your " main. I' m sorry for the late reply, but you should use Qt 4. 7 from the git repositories. All the necessary changes are in there and it builds cleanly with sezero' s toolchain, out of the box. Don' t use " Other linker options".

    Use the " Link libraries" section. Add the following items. mingw32 SDLmain SDL You can put - mwindows in the " Other linker options" section. MinGW is a native Win32 port of the open source GNU Compiler Collection, and can be used to write applications targeting Windows in languages such a C and C+ + ( see the MinGW web site for further details of the supported programming languages). C+ + is case sensitive and must have been trying to use the Main( ) Function which I believe is a backwards WinMain( ) used back in the Windows 3. 1 era, but not sure about that. I would offer you to use MinGW if you are wishing to do c+ + programming with an open source compiler. The Eclipse Foundation - home to a global community, the Eclipse IDE, Jakarta EE and over 350 open source projects, including runtimes, tools and frameworks. WinMain is the entry point for a win32 GUI app. I' m not familiar with eclipse, but it sounds like you made the wrong project type. You want a " console" or " command line" app. undefined reference to GitHub Gist: instantly share code, notes, and snippets. If I' m not mistaken, " Undefined reference to is just Mingw' s way to report that the linker didn' t find main ( or WinMain). ( If it is not there, how' s it supposed to know which it should be. Here is what resolved this problem, as per part of the FAQ at Dev- C+ + website: void WinMain " changed to" int main( ) allowed the compilation to complete and create main.

    Note: if you only change WinMain to main and keep the void, likely your compilation will continue to fail. It is a bug that a user assumes to have a working WinMain in a console application ( what ever mingw. org behaves here). So this bug will be closed. As we talked on IRC, too.

Please don' t fill out this field.

    The fastest way right now for you to check your code would be to open up a command line and compile the program from there. Let' s say you installed MinGW to C: \ MinGW32. Then at the command prompt, you would go to the directory with the code file, then you would type C: \ MinGW32\ bin\ g+ +. Your WinMain should initialize the application, display its main window, and enter a message retrieval- and- dispatch loop that is the top- level control structure for the remainder of the application' s execution. WinMain is the entry point for Microsoft Windows API programs, the suffix is the name- mangling carried out by C+ + compilers. WinMain is the equivalent of main for windows programs only. So if you get this undefined reference to error, just make sure that you have your main in one of the files that you are compiling and don’ t do like I did by leaving out your. exe out of your command. MinGW - Minimalist GNU for Windows A native Windows port of the GNU Compiler Collection ( GCC) Brought to you by: cstrauss, earnie, gressett, keithmarshall. I am using codeblocks and I just started to try Windows programming, and everytime I try to build it, I get the debugger message: undefined reference to.
