winegcc & stdin

[Leon Bogaert]

I'm getting an error when using winegcc with stdin:
> $ cat test.c | winegcc -xc -c -
> gcc: warning: ‘-x c’ after last input file has no effect
> gcc: error: -E or -x required when input is from standard input

Does anyone know what I could be doing wrong? I'm trying to use stdin
because that's what the go (cgo) build tool is trying to use.

I think it's not you who does something wrong, it's winegcc which runs
gcc a bit wrongly. If you look at gcc command line arguments, you'll
get something like

-fshort-wchar -DWINE_UNICODE_NATIVE -D_REENTRANT -fPIC -DWIN64
-D_WIN64 -D__WIN64 -D__WIN64__ -DWIN32 -D_WIN32 -D__WIN32 -D__WIN32__
-D__WINNT -D__WINNT__ -D__stdcall=__attribute__((ms_abi))
-D__cdecl=__attribute__((ms_abi)) -D_stdcall=__attribute__((ms_abi))
-D_cdecl=__attribute__((ms_abi)) -D__fastcall=__attribute__((ms_abi))
-D_fastcall=__attribute__((ms_abi)) -D__declspec(x)=__declspec_##x
-D__declspec_align(x)=__attribute__((aligned(x)))
-D__declspec_allocate(x)=__attribute__((section(x)))
-D__declspec_deprecated=__attribute__((deprecated))
-D__declspec_dllimport=__attribute__((dllimport))
-D__declspec_dllexport=__attribute__((dllexport))
-D__declspec_naked=__attribute__((naked))
-D__declspec_noinline=__attribute__((noinline))
-D__declspec_noreturn=__attribute__((noreturn))
-D__declspec_nothrow=__attribute__((nothrow))
-D__declspec_novtable=__attribute__(())
-D__declspec_selectany=__attribute__((weak))
-D__declspec_thread=__thread -D__int8=char -D__int16=short
-D__int32=int -D__int64=long -D__WINE__ -c - -xc
-isystem/usr/include/wine/windows

Notice that '-xc' has moved after '-c -'. Maybe this should be
considered a bug of winegcc.

Thanks! I've filed a bug: https://bugs.winehq.org/show_bug.cgi?id=38300
