NEMO compilation notes

These are just my own notes for compiling NEMO on a variety of clusters and computers in a public place largely so I can look it up as long as I have internet; if it happens useful for you, great! Please consult the NEMO page for the official details.

While it is fairly straightforward on a supported cluster/supercomputer (e.g. try NOCL ARCHER guide) it can be a bit temperamental on a local machine largely down to library and compiler compatibility. The following notes are what I did to get XIOS and NEMO compiling and running, and will display commands with gcc4.9 compilers (which is my default for other reasons). Extra things that need to be modified for other compilers I have tested will be given accordingly (see the top of the individual pages as to which compilers I have tested the notes with).

I added the following to my ~/.bashrc so as to override the default compilers I had (change these if need be):

export CC=/usr/bin/gcc-4.9
export CXX=/usr/bin/g++-4.9
export FC=/usr/bin/gfortran-4.9
export F77=/usr/bin/gfortran-4.9
export CPP=/usr/bin/cpp-4.9
