Re: [Linphone-developers] mediastreamer2 fails to build

[Mark Murawski]

Looks like the ./configure script should have a hard requirement on ffmpeg.

This was the reason for my errors... but now I'm getting this:


make[2]: Entering directory

# ldd /apps/linphone-bctoolbox/lib/libortp.so | grep tool
        libbctoolbox.so.1 => 
/apps/linphone-bctoolbox/lib/libbctoolbox.so.1 (0x00007f0d52ee2000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6

libortp.so is correctly linked to 
/apps/linphone-bctoolbox/lib/libbctoolbox.so.1



# nm -D /apps/linphone-bctoolbox/lib/libbctoolbox.so.1  | grep bctbx_
<partial list>
000000000000f170 T bctbx_remove_log_handler
000000000000f060 T bctbx_log_handler_set_domain
000000000000f040 T bctbx_log_handler_set_user_data


And lo and behold that /apps/linphone-bctoolbox/lib/libbctoolbox.so.1 
corrently contains the required symbols.

I'm at a bit of a loss as to why this can't link.
