Compiler test fails, gcc on redhat

Question

I'm trying to install LISTSERV by lsoft.com on redhat. The package comes with a compiler test, and this test is failing.

The OS is:

Red Hat Enterprise Linux Server release 6.8 (Santiago)

The Arch is:

x86_64

The compiler is:

gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-17)

Here's the full "gcc -v":

Using built-in specs.

gcc version 4.4.7 20120313 (Red Hat 4.4.7-17) (GCC)

compilertest.c:

main()
{}

The compiler test command:

gcc -O compilertest.c

The error message:

/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../crt1.o: could not read symbols: File in wrong format collect2: ld returned 1 exit status

The file exists as a real file (i.e. not a symbolic link):

-rw-r--r-- 1 root root 1240 Jan 28 2016 /usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../crt1.o

So, what am I missing? Was something compiled using 32b instead of 64b? Am I missing a library or have the wrong version of one?

During the install script, this comes up: "Your compiler does not appear to work. (test was "gcc -O compilertest.c", the script expects a.out default binary name) Only pre-compiled binaries will be available for installation." And, of course, the precompiled binaries don't work either. — Stephen Jarjoura
Can you show the output of readelf -h /usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../crt1.o — Mark Plotnick
Mark, I've added the information you requested to the question above. — Stephen Jarjoura
Please add the output of gcc -v compilertest.c (which will show the paths being passed to the linker, and might explain why it's trying to use that 32-bit object file). — Jonathan Wakely

This error message:

/usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../crt1.o: could not read symbols: File in wrong format collect2: ld returned 1 exit status

Indicates that the linker found a 32-bit object file where it expected a 64-bit one, or vise versa. You can determine which by examining the file in question with the file command. readelf is a little bit overkill for this purpose, but it gets the job done, too. We know as a result that yours is a 32-bit ELF object file, so presumably the compiler expected a 64-bit one.

The path you present canonicalizes to /usr/lib/crt1.o. On RHEL6, that belongs to the 32-bit glibc-devel package (the 64-bit analog lives in /usr/lib64). A 32-bit ELF object is exactly what that file should be, so if the compiler expected a 64-bit object then something is seriously wrong with it.

My best guess is that an installation from source or from a package for some other RPM-based distribution (maybe even a different version of RHEL) has produced an unusable environment for you. If you have an installed-from-source copy of GCC somewhere other than /usr/bin, then removing that (from the path, at least) might be sufficient to solve your problem. The command which gcc might be useful in determining whether you're getting a rogue gcc instead of RHEL's standard one.

Otherwise, your best bet is to remove all copies of gcc and your development libraries, and then reinstall from the official package repositories. The main packages to remove and reinstall are 'gcc' and 'glibc-devel'; removing these may cause other tools and development libraries to be removed as well. I recommend also removing any 'compat-gcc' package. Do not attempt to remove the main 'glibc' package, however, for if you somehow managed to do that, it would render your system inoperable.
