GCC exports function name only from dll

I have a dll, it exports a function ...

extern "C" int __stdcall MP_GetFactory( gmpi::IMpUnknown** returnInterface ) { }

I am compiling this using the Code :: Blocks GCC compiler (V3.4.5). Problem: as a result, the dll exports the decorated function name ...

 MP_GetFactory@4

This does not load, it should just be old ...

 MP_GetFactory

I investigated this for about 4 hours. I think -add-stdcall-alias is an opportunity to fix this. My code :: Log Lock ...

mingw32-g ++. exe -shared -Wl, -out-implib = bin \ Debug \ libGainGCC.a -Wl, - dll obj \ Debug \ se_sdk3 \ mp_sdk_audio.o obj \ Debug \ se_sdk3 \ mp_sdk_common.o obj \ Debug \ Gain \ Gain.o obj \ Debug \ Gain \ gain.res -o bin \ Debug \ GainGCC.sem --add-stdcall-alias -luser32

.. so I think the right option is there? But no luck. Dependancy Walker shows only the exported name. I got it to work using __cdecl instead of __stdcall, then the name is then exported normally, but the function corrupts the stack on the call (since the caller was expecting another calling convention).

Sorry to answer my own question, finally figured it out.

Project / assembly options / linker / other linker options -Wl, - kill-on

... kills the @ decoration symbol, etc.

I think it should be -Wl, - add-stdcall-alias, and the kill-at tricks will render the import library file unusable.
