g++ gives an ld error when I compile with -m32 flag.

I'm running a 64-bit RHEL5 with g++-version 3.4.3

My main.cpp file is nothing more than a main() as follows ...

Code:

 

#include <iostream>



using namespace std;



int main()

{

  return 0;

}

and when I try to compile as:
g++ -m32 main.cpp

it gives me an ld error as follows...
/usr/bin/ld: crt1.o: No such file: No such file or directory
collect2: ld returned 1 exit status

any idea why this might be happening, and how to compile as a 32 bit ...

any help is greatly appreciated... thanks for looking

Taking a bit of a guess, but do you have 32 bit versions of the C++ standard libraries installed? I'm guessing it's trying to find them to link against and failing. If you only have a 64 bit version of the C++ standard library you will need to install a 32 bit version.

So, will I have another /usr/bin/g++ like /usr/bin/g++32?

I'm thinking that I should have the 32 bit libraries?
