Dear friends,


I want to build OpenFOAM-2.4.0 in Ubuntu 20.4.

I have switched the older versions of gcc-4.7/g++-4.7, or gcc-4.8/g++-4.8 or gcc-5.0/g++-5.0 in stead of the gcc-9/g++-9. Then follow the steps in https://openfoam.org/download/2-4-0-source/, such as :



1. Install dependent packages;
2. Set environment variables,

source $HOME/OpenFOAM/OpenFOAM-2.4.0/etc/bashrc

;
3. ./Allwmake > log.make 2>&1


Finally I failed. I put the log file in attachment. I wish to get some help.


Best regards,


Chengan
