buoyantBoussinesqPimpleEHDFoam specifies OpenFOAM v-4.1. As I was not prepared to figure out how to build such an ancient version from source, on the latest Ubuntu, I decided to try the Docker image openfoam/openfoam4-paraview50. However when attempting to wmake the source for buoyantBoussinesqPimpleEHDFoam, I was stumped by this error:

/usr/bin/ld: cannot open output file /opt/openfoam4/platforms/linux64GccDPInt32Opt/bin/buoyantBoussinesqPimpleEHDFoam: Permission denied
collect2: error: ld returned 1 exit status
/opt/openfoam4/wmake/makefiles/general:132: recipe for target '/opt/openfoam4/platforms/linux64GccDPInt32Opt/bin/buoyantBoussinesqPimpleEHDFoam' failed
make: *** [/opt/openfoam4/platforms/linux64GccDPInt32Opt/bin/buoyantBoussinesqPimpleEHDFoam] Error 1

Apparently openfoam4-linux (which invokes docker) initializes environment variables to point at /opt, which is owned by root, rather than /home/openfoam which is owned by the user, but AFAIK there is no way to execute either sudo or su from the shell provided by that docker image.

Here are the relevant environment variables:
