Re: [Linphone-users] Cross compilation error ::cannot find -lv4l1

[Alastair Johnson]

In 3.1.0 building for armv4t with openembedded the v4l parts of mediastreamer 
are being built despite the --disable-video option. Building 3.1.2 natively on 
amd64 the v4l parts aren't built with --disable-video. I haven't looked any 
closer into it to find out if it was a bug that was fixed between versions, or 
if it's something that only happens building for certain targets. It would 
probably have failed to build if openembedded hadn't already built the 
dependencies because they were required by other packages, so I should 
probably investigate further.

For you the soluton may be to try 3.1.2 or later, or to crosscompile the 
required libs and stick them somewhere ld can find them. I can't help further 
than that because all my crosscompile experience has been via build systems 
like openembedded, openwrt and gentoo that look after dependencies for me.
