[OpenFOAM.com] Errors during openmpi installation

WTH_9631 · October 12, 2023, 10:26

Hello everyone，

I am trying to install OpenFOAM 4.1 and ThirdParty pack by compiling source code on RHEL 7.9 system (since I am not able to root). But it seems that no openmpi commands could be found so I firstly tried to install openmpi 1.10.2, which fits OpenFOAM 4.1 well, in the system. After I execute commands:

./configure

make all

the procedure reported errors like this page:

I cannot understand what the problems are. Please, if someone get an idea, please tell me. As a fledgling in using OpemFOAM on RHEL system, I sincerely appreciate your help! And if you have any question on the information about the configuration of the enviroment variables, please do not hesitate to tell me!

Thank you very much for your help!!

PS: My gcc version is 4.8.5

I don't use RedHat, but if I remember correctly you need to use modules (eg, "module avail", "module load" etc) to get the proper MPI loaded. With SuSE they have an mpi-selector to define things. With Ubuntu I think they only have one MPI anyhow (could be mistaken).
