Can we see the code where you set up the salt and call the function?

Can we also see what you /are/ getting for results, if any?

Also, what are your linker options?  One thing that occurs to me is
that you might be linking against OpenSSL's crypt(), rather than glibc's
crypt().  I'm not positive this is a real possibility, but I thought
OpenSSL provided a crypt() function...  You might want to see what
package provides libcrypt* on your system...

The man page for crypt(3) on my system suggests that the crypt()
function might fail because it may not have been implemented, due to
export restrictions...
