I downloaded a binary file that was compiled (a C program) using GCC 4.4.4 for x86-64 Red Hat Linux.
Is it normal that when I try to run it on a Mac OS X (running Lion so also x86-64) running GCC 4.2.1 that it would say: cannot execute binary file? It can’t detect it as a binary file.
Why would it do that? I believe the gcc version has nothing to do with that since the file has already been compiled. It has been compiled for x86-64 of which both machines run. Can someone please explain?
It’s highly unlikely that a binary compiled for a particular OS will run on another. Either get a binary for Mac, or get the source and compile it yourself.
There are many things that will cause issues – version of libc and libstdc++, there can be difference in versions of .so libraries – different API interface to the OS itself. Or even a different binary format (ie VMS binaries do not run on AIX).
