[OpenFOAM.com] Error installing OpenFoam2406 : fatal error: mpi.h: No such file or directory

feacluster · September 3, 2024, 14:54

I am following the instructions here:

https://develop.openfoam.com/Develop...r/doc/Build.md

I copied the ThirdParty-v2406 folder to the OpenFOAM-v2406 directory and renamed it "ThirdParty". I then run "./Allwmake -j -s -q -l". It seems to run the ThirdParty installations, but after some minutes dies with:

fatal error: mpi.h: No such file or directory

I also tried running "makeOPENMPI" from the ThirdParty directory. That completed ok. But still I got the same error when running " ./Allwmake -j -s -q -l " . Not sure if there are additional steps to tell Openfoam to use it?

OS is RedHat 8.6 .

If i try and install from yum I get:

root@mymachine:~# sudo yum install openmpi-devel

No match for argument: openmpi-devel

Error: Unable to find a match: openmpi-devel

Think I figured it out. I first intstalled openmpi from the third party folder by running "makeOPENMPI". Next I changed the line from systenopenmpi to openmpi in this file:

https://develop.openfoam.com/Develop...406/etc/bashrc

Then I resourced the etc/bashrc
