Re: [Linphone-developers] Linphone-wx linking errors

[Simon Morlat]

Hi,
You are surely linking against a mediastreamer2 that wasn't compiled with 
video support. or maybe just src/videostream.c was not included in the 
project.
Are you using mediastreamer2 from cvs ? It is recommended.
Compiling with mediastreamer2.dev in win32native with wxdev-cpp works fine for 
me.
