Hello there,
Yesterday I finished compiling OpenFOAM+ v2006, and I'm sure I did successfully as the "post-compilation steps" went smoothly, follow this instructions https://develop.openfoam.com/Develop...p/doc/Build.md
But when I moved to ThirdParty according to https://develop.openfoam.com/Develop...velop/BUILD.md, it went complex:
_ first,

 ./makeFFTW -help

showed

 Error (makeFFTW) : not located in $WM_THIRD_PARTY_DIR
      Check your OpenFOAM environment and installation

_then,

 which mpicc

lead to

 /usr/bin/which: no mpicc in (/home/username/simFlow/simFlow-4.0:
/home/username/simFlow/simFlow-4.0:
/home/username/anaconda3/bin:
/home/username/anaconda3/condabin:
/home/username/.local/bin:
/home/username/bin:
/usr/lib64/ccache:
/usr/local/bin:
/usr/bin:
/bin:
/usr/local/sbin:
/usr/sbin:
/usr/lib64/mpi/gcc/openmpi/bin:
/home/username/basilisk/src:
/usr/lib64/mpi/gcc/openmpi/bin:
/home/username/basilisk/src)

I have no clue why this happened because I installed openmpi peacefully. (This alert was a straight line, I splitted them to rows for easy to see)

_ for "Adjust the etc/bashrc, etc/config.sh/...", I tried to look at them but seeing nothing to adjust.
_these commands "./makeGcc" "./makeLLVM" "./makeCMake" all lead to

 Error (command_name) : not located in $WM_THIRD_PARTY_DIR
     Check your OpenFOAM environment and installation

_finally "./Allmake" command also has the same result.
So I think the problem is something in "not located in $WM_THIRD_PARTY_DIR
Check your OpenFOAM environment and installation"

but I don't have a clue to solve it, I tried to find $WM_THIRD_PARTY_DIR in /OpenFOAM/OpenFOAM-v2006/etc/bashrc and some files recommended as above but seeing no where to change the value.
Before asking there, I have re-compiled the whole program because I thought the problem is changing directory (I compiled OF in a dir, then moved them to another dir, it still run "post-compilation steps" smoothly so that's not the reason). Now the problem is stand still, I have to change some values, I guess.
//ehh, by the way, I find the ThirdParty guide is not as explicit as the Main guide.
I use Fedora 32 if that helps.
