Add -lICE -lSM to your compile (link) options.

In general, you can find missing symbols on your system by doing
a 'nm libwhatever.a' on each libwhatever you want to check. So if
you're missing a symbol 'sym', here's a brute-force way to look for
it in every library on your system:

find / -name lib\*.a -exec nm {} \| grep sym \;

Note it'll take find a long time to just find all the libraries.
You can improve on this. But this is a good first start, to make sure
you find and check every library.
