[OpenSIPS-Users] rtpproxy compile

Hi, Denis!

Can you run 'ldconfig -p | grep sndfile'? Do you see the .so libraries 
in the output? If not, perhaps you should run 'ldconfig'. If this still 
does not work, you should manually add the library's directory in the 
library path[1].

If you do get sndfile in the output, but it still does not work, perhaps 
the first configure commmand did not get the proper library, so you 
should re-run './configure'.

PS: I also forwarded this question on the RTPProxy mailing list. If this 
does not work, perhaps somebody out there can help you out.


Best regards,
