Error message: 'Your "MINGW*" operating system is not supported by this release of OpenFOAM'

Symptom

After starting the blueCFD-Core 2016-1 terminal, a message similar to the following appears:

Your "MINGW64_NT-10.0" operating system is not supported by this release of 
OpenFOAM. For further assistance, please contact www.OpenFOAM.org

bash: sed: No such file or directory
bash onWin: command not found

[wyldckat]

Reason

After considerable debugging the issue, the conclusion was that:

1. The FOAM_INST_DIR was not being properly set, because it was overridden by OpenFOAM's etc/bashrc

2. The prefs_mingw_w64.sh was not found by foamEtcFile.

Both issues are related to a delay in the mount at /home/ofuser/blueCFD, which results in the files not being found. It's still not clear as to why this happened, but it's possible that is was after the user installed something new that broke MSys2's search system.

Solution

1. Comment out the FOAM_INST_DIR lines in OpenFOAM-4.x/etc/bashrc.

2. Use the full path in ~/.blueCFD/of4x.sh for the prefs files.
