[Linphone-developers] mediastreamer2 configure error

[enrico . benetti]

Hi all,
I've got a problem trying to cross-compile linphonec for arm, with video 
enabled.
I've compiled and installed all dependencies in a non standard path 
INSTDIR/PFX, then I try 
to run configure for linphone: it fails with SDL, because linking of ffmpeg 
libavutil.so fails while 
running conftest.o building.

Here it is the error message from mediastreamer2/config.log:
*********************************************************************

Same thing happened for "checking av_codec_register_all" test, but I've solved 
with 
FFMPEG_LDFLAGS="-L<ffmpeg_path> -lavcodec -lavutil".
I'm not able to pass this -lavutil linker option to previous phase, so 
configure fails.
--with-sdl path is ok (header test is ok).
Obviously library belongs to -I<..../opt/lin/lib> folder, so it's a ld mess, I 
think.

I'm using freescale iMX27 gcc-4.1.1 toolchain, within ltib environment, but 
this is not the 
problem,because linker fails also working in a "plain" cross-compiling 
environment.

I've succesfully compiled version without video support, and now I'm trying to 
port also video.
Has anyone already faced this problem? Thank you very much for your kind 
support,
Enrico
