Load a C library into extension?

Hi all, I have no doubt posted many queries here in the past few days, and am thankful for all the help I have received. :) I have been able to write a helloworld extension and compile it. The next step is to call a function in a library libfoo.so. I think this needs a modification in config.m4. Any ideas how to go about it? I have already tried editing LIBNAME and LIBSYMBOL. It says: checking for foo in -lfoo... no configure: error: wrong foo lib version or lib not found The file is present as ext/myext/lib/libfoo.so.
