| er, why did you not give us the complete commandline you used? I chopped out the names of the source files. I figured it would be pretty self-explanitory by providing only relevant parts of the command line. However, you're right, I was missing the -shared flag. Silly me. cc -shared -Wl,-export-dynamic -o foo.so foo.c does what its supposed to.
