May be you can rely on the tool module-environment with linux. It allow you to set environments to use different versions of a same application. It is used on the french HPC centers and I use it to manage several paraview version and... several gcc/gfortran versions (4, 7, 9) on my servers and on the cluster. It is available in all linux distribution. Just load your tailored module (setting PATH, LD_LIBRARY_PATH....) to activate the gcc version needed and compile/execute On redhat 7 based OS look at environment-modules-3.2.10-10.el7.x86_64 Patrick Le 29/05/2020 à 05:07, Dan Kegel a écrit : > https://stackoverflow.com/questions/13334300/how-to-build-and-install-gcc-with-built-in-rpath > is a bit dated, but might be helpful.
