I have the 32b and 64b version of a third party shared library that I am trying to link against. I can link fine against the 32b version on a 32b FC5 machine just fine. The 64b version (also on FC5), however, gives the following error: /usr/bin/ld: ./ams_read: hidden symbol `atexit' in /usr/lib64/libc_nonshared.a(atexit.oS) is referenced by DSO /usr/bin/ld: final link failed: Nonrepresentable section on output collect2: ld returned 1 exit status Any ideas on what the problem is? Is it a problem with FC5 or with the shared library? Lane
