I'm attempting to build OpenFOAM 2.3.x on a RHEL6 based cluster, and running into some issues. First, it seems the compiler can't find mixtureKEpsilon.H:

phaseCompressibleTurbulenceModels.C:56:29: fatal error: mixtureKEpsilon.H: No such file or directory
 #include "mixtureKEpsilon.H"
                             ^
compilation terminated.

The software environment of the cluster is:

• GCC 4.8.1
• cmake 2.8.10.1
• Open MPI 1.6.5
• Boost 1.41

Note that I was initially going to use the instructions on the wiki, but it seemed the dependencies were met, considering the list above (I also don't have root privileges), so I just went and ran Allwmake in $WM_PROJECT_DIR.

It seems most of the applications built fine, with the exception of any that rely on phaseCompressibleTurbulenceModels lib, which I don't need. However, I was attempting to run snappyHexMesh in parallel on a case where it worked fine in the past, and ran into mysterious mpirun errors. I am thinking a clean compilation would be smart, to ensure this is not the problem.

Any ideas on what's going on here?

Greetings Pete,

That problem usually occurs if you already had the git version of OpenFOAM already compiled/installed sometime ago, then have made a recent "git pull" from the latest git repository for OpenFOAM and then ran Allwmake once again.
This can occur because new files appear with the latest repository changes and which are not automatically catalogued by the compiling/building system that OpenFOAM uses.

There is also a possibility that something important failed during the "git checkout" (it's one of the last internal steps of "git clone" and "git pull"), where a file might not have been written properly due to some problem.

Either way, you can try running the following command before running Allwmake once again:

wcleanAll

which should clean out all of the existing built installation for the current build options, without changing/damaging the source code.

Best regards,
Bruno

As usual, you are right Bruno!

I had partially compiled with an older version of g++. After cleaning everything out and recompiling with 4.8.1, the applications I need are working fine. There are some other issues, but I am not worried about those fore now.
