Wine C and C++ MinGW Compatible Compiler


winegcc [options] infile...


winegcc is a gcc wrapper which tries to provide a MinGW compatible compiler  under Linux. This is most useful to Win32 developers who can simply  take their MinGW code from Windows, and recompile it without  modifications under Winelib on Linux.  wineg++ accepts mostly the same options as winegcc.

The goal of winegcc is to be able to simply replace gcc/g++/windres with winegcc/wineg++/wrc in a MinGW Makefile, and just recompile the application using Winelib under Wine. While typically there are  small adjustments that must be made to the application source code  and/or Makefile, it is quite easy to do them in a fashion that is compatible between the MinGW and Wine environments.

This manual will document only the differences from gcc; please consult the gcc manual for more information on those options.


gcc options: All gcc options are supported, and are passed along to the backend compiler.

-b,--target target

Specify the target architecture triplet for cross-compiling. winegcc will then invoke target-gcc instead of gcc.

--wine-objdir dir

Specify the Wine object directory. This is used when building Wine itself, to use the includes and libraries from inside the build tree.

--winebuild name

Specifies the path and name of the winebuild binary that will be launched automatically by winegcc.  If not set, winegcc will look for a file named winebuild in the path. This takes precedence over the WINEBUILD environment variable.


Override the underlying type for wchar_t to be the default for the  target, instead of using short unsigned int, which is the default  for Win32.


This option passes '--subsystem console' to winebuild, to build console applications. It is the default.


Use Wine implementation of MSVCRT, instead of linking against the host system libc. This is necessary for the vast majority of Win32 applications, as they typically depend on various features of MSVCRT. This switch is also used by the MinGW compiler to link against MSVCRT on Windows, instead of linking against Cygwin libc. Sharing the syntax with MinGW makes it very easy to write  Makefiles that work under Wine, MinGW+MSYS, or MinGW+Cygwin.


Set the default entry point of the application to be the Unicode wmain() instead of the standard main().


This option adds -lgdi32, -lcomdlg32, and -lshell32 to the list of default libraries, and passes '--subsystem windows' to winebuild to build graphical applications.


Do not use the standard system libraries when linking. These include at a minimum -lkernel32, -luser32, -ladvapi32, and  any default libraries used by the backend compiler. The -mwindows option augments the list of default libraries as described above.


Do not add the winecrt0 library when linking.


Pass an option to winebuild.  If option contains commas, it is split into multiple options at the commas.


When linking a dll, also create its corresponding import library.



Specifies the path and name of the winebuild binary that will be launched automatically by winegcc.  If not set, winegcc will look for a file named winebuild in the path.


winegcc defines __WINE__, for code that needs to know when it is being compiled under Wine. It also defines WIN32, _WIN32, __WIN32,  __WIN32__, __WINNT, and __WINNT__ for compatibility with MinGW.


The dllimport/dllexport attributes are not supported at the moment, due to lack of support for these features in the ELF version of gcc.

Static linking is not currently supported against Wine DLLs. As a result, the -static, --static, and -Wl,-static options will generate an error.

Bugs can be reported on the Wine bug tracker.


winegcc was written by Dimitrie O. Paun.


winegcc is part of the Wine distribution, which is available through WineHQ, the Wine development headquarters.
