I am trying to create a linked library (Sofia-SIP libraries) within the
./petalinux-dist/lib tree. When trying to link to those libraries it
errors out with undefines (see below). Using mb-linux-nm shows the
modules are there (see below). Following is the makefile.
thanks for the help.............chris

Try putting the the -lsofia-sip-ua parameter at the end of the gcc commandline, rather than the beginning. Here's results from my trivial test:
# -llib early in the commandline - bad
[jwilliams@g613-9373 libfoo]$ gcc -L . -llib -o main main.c
main.c: In function ‘main’:
main.c:4: warning: return type of ‘main’ is not ‘int’
