[Linphone-developers] Compile error: Could NOT find OpenH264 (missing: HAVE_WELS_CREATE_DECODER)

[Mostafa Farzane]

I am trying to compile linphone-sdk on debian 9. Here are the commands to compile:

cmake -DENABLE_NON_FREE_CODECS=YES -DENABLE_OPENH264=YES -DENABLE_EMBEDDED_OPENH264=YES -DENABLE_FFMPEG=YES -DENABLE_GPL_THIRD_PARTIES=YES ../
cmake --build . --parallel 4

The ouput:

[ 65%] Completed 'EP_openh264'
[ 67%] Built target EP_openh264
[ 67%] Performing configure step for 'EP_msopenh264'
loading initial cache file /home/mosi/projects/sip/linphone-sdk/build/WORK/desktop//tmp/EP_msopenh264/EP_msopenh264-cache-RelWithDebInfo.cmake
