There's nothing wrong with your Fink setup. I'm assuming that what's going on is that your Fink is 32-bit (you didn't specify). Apple's compilers on Snow Leopard build as 64-bit by default, so your test example is expecting to link to 64-bit libraries. The fix is mentioned in http://www.finkproject.org/faq/usage-general.php?phpLang=en#compile-myself specifically, export PATH=/sw/var/lib/fink/path-prefix-10.6:$PATH which puts special scripts that wrap the compilers with architecture-appropriate flags at the head of the PATH. That way your "gcc42" will know to build as 32-bit. - -- Alexander Hansen, Ph.D. Fink User Liaison -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkzUoXkACgkQB8UpO3rKjQ9IagCgjjCBp0o5DYlUE4l2Iigj5xcb NO4An1GJKf+xNEAN/7RQ18Gld7HNIi49 =uDjl -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ The Next 800 Companies to Lead America's Growth: New Video Whitepaper David G.
