Re: DShow Build Issues

Hi Brendan,

I am as clueless as you with regard to why your environment is different
than mine ;) Note that my build host is linux and not cygwin...

I also don't get such warnings upon linking here and am again quite
clueless what could be the reason. Have you freshly compiled the
strmbase.lib you are linking against with your current toolchain?

If not, you should try to recompile baseclasses using your current
toolchain (and hope that not too many other new problems arise then ;)).

Regards,
Michael
