Adding ogg vorbis encoding to my project

Question

For my MFC application, I need to convert .wav data in an array into ogg vorbis format.

I compiled both libogg and libvorbis as static libraries. I created "bin" directory in my project folder and placed there libvorbis_static.lib and libvorbisfile_static.lib. Also, I created in the bin directory libvorbis folder, and an include folder in it, and placed there vorbis (with codec.h, vorbisfile.h, vorbisenc.h) and ogg (with os_types.h and ogg.h) folders. I added libvorbis_static.lib to additional dependencies of my project and the bin folder to Additional Library Directories.

When I am trying to compile, I get errors:

1>libvorbis_static.lib(info.obj) : MSIL .netmodule or module compiled with /GL found; restarting link with /LTCG; add /LTCG to the link command line to improve linker performance

I am confused. Could you please help? Thanks.

Answer 1

LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library

It's nothing to do with orbis, this is what you get when you try and link both the c stdlib and MFC's C stdlib in the same program - just do what the compiler tells you. Or just set it to ignore libcmt/d

Answer 2

Check what c-runtime you compiled ogg-vorbis with. It must match your app if you're linking statically.

If you've compiled vorbis to a DLL instead, you might be able to use separate c-runtimes (if memory allocated by the vorbis DLL is always freed by that DLL, and it's a c-only API).
