Re: [Linphone-users] msilbc build error (anyone?)

[Stephen Stocker]

  The more I've used Linphone, the more I like it, but I absolutely cannot 
get ilbc working with it. I have the latest msilbc source from the Linphone 
site, and using linphone-2.1.1 source. After compiling and installing 
Linphone using ./configure --disable-video --disable-nls, I build and 
install the ilbc libs without a problem, then cd .., delete the 
MS_FILTER_SET_FMTP line in ilbc.c, export 
LINPHONE_BUILD=/home/lpar/linphone-2.1.1, then make and make install. But 
when I start linphonec -d 6 -l linphone.log, I get the error below. Nothing 
I've tried seems to make a difference, and I'm at my wits end. I've used gsm 
for voice chats, and it works reasonably well, but I suspect ilbc would be a 
superior solution for my very low bandwidth net connection.

  Has anyone run into this problem before, or can someone please offer some 
help? Thanks much in advance! :)
