Re: [Linphone-developers] How to build linphone under Ubuntu

Dear Jonathan,

Thank you very much for your kind reply. However after updating all related packages (speex, osip, eXosip, ffmpeg) to latest version using git clone, I still cannot build linphone. I got errors as follows.

in videoenc.c: CODEC_FLAG_H263P_UMV undeclared.
in videoenc.c: CODEC_FLAG_H263P_SLICE_STRUCT undeclared.
in videoenc.c: FF_I_TYPE undeclared.

I guess the problem is with ffmpeg (which includes libavcodec). However I've tried lower versions and they didn't work either.

What should I do now?

Best,
Arthur Tang

You are on the right track.

I had to build osip and exosip version 3.6.0 in order to then build a
recent linphone on Ubuntu.

Get osip and exosip source from:

git://git.savannah.nongnu.org/osip.git
git://git.savannah.nongnu.org/exosip.git

You can't do this as there is not a sufficiently up to date version of
osip/exosip in the ubuntu package repository. You can check the version
that is available at packages.ubuntu.com

Hope this helps.
Jonathan.
