Have you tried to compile a small program with gcc -m32? Does it work? If
yes, you may try the following commands:
gcc -m32 -print-file-name=crti.o
gcc -m32 -print-file-name=crtn.o
gcc -m64 -print-file-name=crti.o
gcc -m64 -print-file-name=crtn.o
On my system, the outputs are:
> gcc -m32 -print-file-name=crti.o
/usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../lib/crti.o
> gcc -m32 -print-file-name=crtn.o
/usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../lib/crtn.o
> gcc -m64 -print-file-name=crti.o
/usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../lib64/crti.o
> gcc -m64 -print-file-name=crtn.o
/usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../lib64/crtn.o
You may check these outputs and make sure the files exist and are used
correctly.
