Re: [Linphone-developers] mediastreamer2 configure error

[Simon Morlat]

Hi,

Yes I think it's a problem with the linker not finding a library needed by 
another library (libavcodec). 
I think 
export 
LDFLAGS="-rpath 
/media/sdb2/progetti/ltib-imx27ads-20070210/rootfs//opt/lin//lib "
before doing configure
should solve the problem.
