Troubleshooting
Problem
In SLES 11, the gcc and g++ compilers default to 64-bit mode compilation, while the XL C/C++ compilers defaults to 32-bit mode.
Resolving The Problem
If you have dependencies on 32-bit mode with the gcc or g++ compiler, you need to specify -m32 in your compiling command to the gcc or g++ compiler.
If you prefer to use 64-bit mode with the XL C/C++ compiler (eg. xlC, xlc), you need to specify -q64 in your compiling command to the C/C++ compiler.
The default compilation mode of the gxlc and gxlc++ utilities becomes 64-bit, in order to match the gcc and g++ compilers.
