Thanks Alexandros and Alexandre for the suggestions. What finally wound up making it work is the following, if anyone is interested:
libtool gcc -g -o test second.c -lpthread /usr/local/lib/libsmdi.la For now I am happy with anything that gets it to work, but I would like to eventually be able to build libraries in a way that by linking to them, any libraries that they require (in this case, pthreads) are automatically linked also. I will pose this question to the libtool list and see what happens. Thanks again, John
