Sorry if this is the wrong place to be posting such questions; however, I'm
having issues with Sofia on Mac OS X. It compiles cleanly and it's easy
enough to get the example programs to link against libsofia-sip-ua; however,
when I go to start one this is the issue:
gcc -I/usr/local/include/sofia-sip-1.12 -L/usr/local/lib -lsofia-sip-ua -o
hello sofia.c
68-26-33-60:sofia dcorbe$ ./hello
dyld: Symbol not found: ___CFConstantStringClassReference
Referenced from: /usr/local/lib/libsofia-sip-ua.0.dylib
Expected in: flat namespace
Trace/BPT trap
Here's the content of sofia.c:
