Hi!

For those who haven't just applied the 2.0-patch to the shiny new OpenFOAM 2.1.x here comes a set of patches to get it to run.

This time you have the choice:
a) use the gcc 4.2 that comes with Apple XCode (advantage is: you'll only have to install one compiler)
b) use gcc 4.6 from MacPorts (advantage: supposedly faster)

Basically do the same as if you would install OF from sources on a Linux-Machine (so I'll be sketchy):

1. Download OF 2.1 (preferably via git) and Thirdparty-2.1 and unpack them on a case-sensitive filesystem (see elsewhere what this means)

2. Go to the ThirdParty-Directory and apply the first patch
patch -p1 <ThirdParty-2.1.0-Mac.patch

3. Go to the OpenFOAM-Directory and apply the base-patch
patch -p1 <OpenFOAM-2.1.x-Mac.patch
then make the script that helps with the tracedumps executable (if the patch-utilitiy didn't do it)
chmod a+x bin/addr2line4Mac.py

4. Now decide which compiler you're going to use (although you can also apply both patches if you want to)
a) gcc 4.2: apply the appropriate patch:
patch -p1 <OpenFOAM-2.1.x-gcc42.patch
(this patch fixes some places where gcc4.2 can't cope with advanced constructs)
b) gcc 4.6: apply
patch -p1 <OpenFOAM-2.1.x-Mac-gcc46.patch
and make sure that the WM_COMPILER environment variable is set to Gcc46 (preferably in site/2.1.x/prefs.sh)
c) other compiler: copy wmake/rules/darwinIntel.. that the patches create. Basically only the compiler name has to be changed in the c ant the c++-file if you use gcc

5. Now source etc/bashrc, grab some coffee and compile

As usual I didn't bother to get the PV3Reader (aka paraFoam) to compile. Use an up-to-date paraview from Kitware with the built in reader for OF

PS: comments on the procedure are welcome. If somebody feels like writing a step-by-step instruction on the Wiki this would be even more welcome
