RE: binary compatibility

Hmmmm...okay, so how do I know which modules system calls need? The man
pages don't list the required libraries. I've got plenty of nss modules
on my Itanium RHL system. They just happen to be 64-bit versions, which
I'm guessing won't work with a 32-bit executable.

If there's a 32-bit lib called libnss_files.so and there's a 64-bit one
with the same name, how do I have both on the same system?

Other OS's for Itanium, such as HP-UX and Windows support
binary-compatibility without my having to figure out which libraries to
copy over and potentially rename.

I'm sure what you've said below is true, but it doesn't really get me
that much farther to solving my problem. I'm happy to read
documentation, but haven't found any yet.

Thanks,

Eric

Statically linked binaries still dlopen() nss modules for
gethostbyname(), etc. If those aren't there, they will fail.
