Trunk doesn't build on OSX

[Adam Candy]

There are attempts to compile Fluidity and its associated software on OSX.
A buildbot is in the process of being set up. This bug report is a vehicle for discussion of progress!

[Adam Candy (asc)]

Current status:
It is possible to build Fluidity on OSX 10.8 with *all* tests passing.

The following branch was used:
https://code.launchpad.net/~asc/fluidity/fluidity-darwin-port-minimal

which contains changes to libwm and to allow METIS 5 and Parmetis 4 to be used (through the DARWIN configure flag - an unashamed hack).

in combination with:
 - custom builds of PETSc 3.3 and Zoltan
 - packages from macports (including GNU tools) and gcc (4.7 was used)
 - selection of GNU tools over OSX defaults
 - links for correct names of MPI executables
 - some environment jiggery-pokery for compile and linking FLAGS
 - Trang is not in macports and was manually installed

Other branches might be useful in https://code.launchpad.net/~asc (they will all have darwin in the name). The more recent branches used James's work on 10.7 - see branch https://code.launchpad.net/~j-percival/fluidity/fluidity-darwin-port.

For the macports local repo, see: /scratch/asc/repo/
Most of it is irrelevant material from a bitbucket branch - see https://bitbucket.org/seanfarley/scienceports
which I tried to use, but have instead gone for the special versions of PETSc and Zoltan that James started. I've modified these, although I'm not sure how much now - take a look in the repo on scratch. The bitbucket branch seemed like a nice approach which allowed different types of MPI to be used - and also has builds of METIS and Parmetis (although not now used in the current setup).

You'll also need trang. I started a Portfile for it, but didn't finish. I based my install on the Ubuntu trang package - basically downloading, unarchiving and installing files.

This setup also provides Diamond, working with XQuartz.
