[Linphone-developers] Linphone-wx linking errors

[António Saragga Seabra]

Hi,

I’m trying to compile Linphone-wx in windows and getting the LINK errors shown bellow. The link error undefined references are actually defined in lines 119–128 of the header file mediastreamer2/mediastream.h. I compiled mediastreamer2 as static using MSVC++ win32native project (to compile had to replace inline by __inline in some ffmpeg header files) and all the rest Linphone subparts and dependencies (libtheora, libogg, libspeex, libavcodec,libresample) also as static libraries using GCC / wxDev-C++. 

These linking errors are somewhat puzzling since all audio related functions defined in the same header file mediastream.h, like audio_stream_new() for example, don’t give any error messages when linking. 

If I could get a helping hand it would be great!
