Hi all,
About 20 years ago I knew how to use this compiler,but I became a mac programmer then windows then mobile and now find myself back to unix again...
I have this error:
/usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/crt1.o: In function `_start
And I've seen it all over the inet, but every case seems to be different.
In my case I'm trying to build a 32bit shared object. I have -shared and -fPIC
set even -m32
Can someone share with me how to tell gcc to use my lib32 directory instead of lib64 which it seems to default to?
Thanks

The 32-bit startups (like 'crt1.o'), libraries and headers aren't
usually installed as default with the "program tools", one must
install these specifically. This happens with "System/Administration"
and there "Add/remove applications" or something in the GUI of an
uptodate Red Hat system...

That's not an error, it's the run up to an error message, telling you
the location of the error. You haven't shown the actual error.

Obviously you're not doing exactly the same thing, or you'd get the
same results.

No -m32 here, so the output file is 64-bit

-m32 here, requesting 32-bit output

It's telling you that AuthModule.o cannot be linked into a 32-bit
file, because it's 64-bit.

Have you used #include <string> ?
