NEMO on MacOSX -- installation comments for Mac OS 10.4.x

Upgrading (G5)

After Xcode was installed one has several options for gnu compilers:

1. Apple's Xcode: in /usr/bin gcc (4.0.1) (but no fortran, so mostly useless for us)
   I found some older versions; gcc-3.3 (build 1819) and gcc3 (build 1256 based on gcc 3.1) in /usr/bin, but they seem to be leftovers from the the previous Mac OS X). See also apple's XCode GCC4 release notes
2. HPC : in /usr/local/bin - gcc (4.2.0).
   You can also optionally install g77 3.4 (3.4.4) with this version of gcc4 instead of the default gfortran. I had an older g77 (3.5.0 20040429) in there which clearly confused some users.
3. fink: in /sw/bin - gcc-4 (4.0.0)
4. darwinports: in /opt/local/bin - gcc33, gcc34, gcc40, gcc41 and gcc42. e.g. gcc-dp-3.4 (3.4.5) gcc-dp-4.0 (4.0.3)
5. I have now heard of one case where the compiler was installed manually from source, but without further details.

• the compilers are not named equally logically, so some $path magic may not always be the full solution. Symlinks or use the CC/CXX/F77 environment variables for configure. (this won't work in miriad yet, so you would need symlinks and a good $path)
• the fortran compiler is called g77 in gcc3, and gfortran in gcc4.
• if you choose gfortran,instead of g77, you may need to edit PGPLOT's driver.list file and redo pgplot.
• The -lcc_dynamic issue seems to have gone away (cf. this). But SMA guidelines make you create a link ot the old libcc_dynamic.a, which probably is not needed if you stay away from g77 and only use gfortran? I'm still a little confused about this.
