gcc: error: unrecognized command line option ‘--showme:link’

I installed OpenFOAM newly and the following error is occurring every time I open my terminal.

gcc: error: unrecognized command line option ‘--showme:link’

As per the guide on the OpenFOAM website, I did the following:

Doing
sudo update-alternatives --list mpi

I get

/usr/bin/mpicc.openmpi

Doing

sudo update-alternatives --set mpi /usr/lib/openmpi/include

I get

update-alternatives: error: alternative /usr/lib/openmpi/include for mpi not registered; not setting

Doing

which mpicc

I get

/opt/intel/compilers_and_libraries_2020.2.254/linux/mpi/intel64/bin/mpicc

Maybe this is the reason. Since I am using mpicc from intel, it is having problem with openmpi

Note:

I have installed openmpi using sudo install openmpi-bin

Hi,

Problem solved!

Thank you Ashley for your suggestion. I had already seen it but I thought that was a problem specific to conda. However, I solved the problem using that thread.

For future reference to other people, I mention below, what I did.

I opened /opt/openfoam8/etc/bashrc

went to line number 89

it looked like 

export WM_MPLIB=SYSTEMOPENMPI

I changed it to 

export WM_MPLIB=OPENMPI

Other options for this variable are mentioned above this. they are SYSTEMOPENMPI, OPENMPI, SYSTEMMPI, MPICH, MPICH-GM, HPMPI, MPI, FJMPI, QSMPI, SGIMPI and INTELMPI

In the thread mentioned in Ashley's comment, they created a file named pref.sh and included the line that I have edited. I believe this way the value of the variable will be overwritten.

I hope, this explanation will be helpful for future OpenFOAM users.

Regards,

Arnab
