hi guys.
i installed openfoam-6 with linux system gcc, etc/bashrc (export WM_COMPILER_TYPE=system), the gcc version is 4.8.0;
now i want install openfoam-v2106. there are some errors in compiled ADIOS2 with gcc-4.8.5, so i changed to gcc-7.5(etc/bashrc export WM_COMPILER_TYPE=ThirdParty), it works well.

my question is:

when i open a new terminal, source openfoam-6/etc/bashrc, the gcc version is 4.8.5; then i source openfoam-v2016/etc/bashrc, the gcc version is 7.5.0;
but then i source openfoam-6/etc/bashrc again, the gcc version still is 7.5.0;
is there has a way, when i source the different openfoam version the gcc can changed rightly?

many thanks.

Not really sure what they are using in openfoam6 for setting/clearing things, but you need to check what is still set. Use the command "env" to display your settings.

env

There you will find various entries. First thing to check is if the value for WM_COMPILER_TYPE is still somehow set to ThirdParty. Next check your PATH. This very likely somehow did not get its values cleaned properly when switching versions.

echo "$PATH" | tr ':' '\n'

This will give you a more readable version of what your PATH contains. This is where the foamCleanPath script comes into play. You can use that to cleanup various environment settings - examples in the etc/bashrc, etc/config.sh/settings ...


Of course, depending on how you have switched between versions (edited your ~/.bashrc file, placed extra setup files elsewhere), it could be that you are causing the problem yourself but just don't recognize where.

thanks olesen

now i creat a .sh file in special version path, the file contains the loaded environment modules.
i was installed of in hpc cluster. and i changed all export WM_COMPILER_TYPE=system
this can also be solved.
