Hello to all,

I would like to install OpenFOAM v2112 in debug mode in Ubuntu 22.04. The compiler used in Ubuntu 20.04 is GCC 9.4. In Ubuntu 22.04 the default is GCC 11.2.0.

This is giving me problems with the installation. I have installed GCC9 with:

sudo apt install gcc-9 g++-9

How can I specify the the GCC version I would like OF to be compiled with?


The error I am getting is:

primitives/functions/Math/erfInv.C: In function ‘Foam::scalar Foam::Math::erfInv(Foam::scalar)’:
