winegcc – Wine C and C++ MinGW Compatible Compiler
winegcc [options] infile…
winegcc is a gcc wrapper which tries to provide a MinGW compatible com‐
piler under Linux. This is most useful to Win32 developers who can sim‐
ply take their MinGW code from Windows, and recompile it without modi‐
fications 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
This option specifies where to find the executables, libraries,
include files, and data files of the compiler itself. This is a
standard gcc option that has been extended to recognize a prefix
ending with ‘/tools/winebuild’, in which case winegcc enters a
special mode for building Wine itself. Developers should avoid
prefixes ending with the magic suffix, or if that is not possi‐
ble, simply express it differently, such as ‘/tools/winebuild/’,
to avoid the special behaviour.
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 Cyg‐
win libc. Sharing the syntax with MinGW makes it very easy to
write Makefiles that work under Wine, MinGW+MSYS, or MinGW+Cyg‐
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 wineb‐
uild 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
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.
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
