Hello,
I am attempting to compile gromacs using gcc 3.x and I would like to
confirm that I have actually obtained what I intended. In order to do
this, I have set my path with the desired version of gcc first:
export PATH=/tools/gcc/3.4.6/bin:$PATH
However, I am not convinced that I am actually getting a gcc 3.x
compiled version because it still finds the default /usr/bin/cc, which
is gcc 4.1.2.
Here is some output from the config.log file.
