Hi all,
I've got a problem trying to cross-compile linphonec for arm, with video 
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 fails while 
running conftest.o building.

Here it is the error message from mediastreamer2/config.log:
configure:23291: checking for SDL_Init in -lSDL
configure:23326: arm-926ejs-linux-gcc -o conftest -DORTP_INET6   -DINET6 -Wall -

o.49, needed by /media/sdb2/progetti/ltib-imx27ads-20070210/rootfs//opt/lin//lib
/, not found (try using -rpath or -rpath-link)
Same thing happened for "checking av_codec_register_all" test, but I've solved 
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 

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 

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
