The GNU Compiler Collection version 4.2.0 has been installed on Njord.
In most cases, it is necessary to use the -maix64 compiler option to avoid 32/64-bit problems.
Use for example the following settings:
export CFLAGS="-maix64 -mcpu=power5+ -mtune=power5+"
export CPPFLAGS="-maix64 -mcpu=power5+ -mtune=power5+"
export LDFLAGS="-maix64"
export CFLAGS="-maix64 -mcpu=power5+ -mtune=power5+"
export CPPFLAGS="-maix64 -mcpu=power5+ -mtune=power5+"
export LDFLAGS="-maix64"
