64-bit with ifort 10.0 on Linux?

Why the heck is the fortran compiler generating 32-bit binaries? All the installed dynamic libraries are 64-bit so I can't even run the resulting binary if it needs linkage to one of the libraries.

This is with the Intel 10.0.026 compiler suite.

Thanks in advance!

Well, it turns out to be a simple solution. There are two compilers one is fc/10.0.026/bin/ifort and the other is fce/10.0.026/bin/ifort. The one in the "fc" generates 32-bit binaries while the one in "fce" generates 64-bit binaries.

I don't own this system and didn't install the compilers so maybe this is obvious if you have the compiler installation manual?

If you read the compiler documentation, this is described. In version 11 it will work a bit differently in that there is one ifortvars.sh script and you supply an argument to it to specify which platform you want to compile for.
