Has anyone been able to successfully link (statically) to a library generated by MinGW? I compiled the libraries in question (FFMpeg avutil, avformat, and avcodec) under MinGW, ran objconv on it to convert it to OMF (no errors) and passed it to optlink along with MinGW's libgcc. At this point I got quite a few undefined references:

 Error 42: Symbol Undefined _snprintf
 Error 42: Symbol Undefined ___strtod
 Error 42: Symbol Undefined _gettimeofday
 Error 42: Symbol Undefined _strncasecmp
 Error 42: Symbol Undefined _strcasecmp
 Error 42: Symbol Undefined ___mingw_vfprintf
 Error 42: Symbol Undefined ___fpclassifyf

I've tried with different combinations of adding mingwex and libcoldname to the mix, but not only do they add some "previous definition" conflicts, neither was able to fix any of the linker errors.

I might be able to manually find & implement all those functions in the MinGW source, would this be the best way?

Thanks,
Robert

Never mind; they weren't as hard to implement as I thought.
