Hello,
till now i have been using a pre compiled windows version of liggghts(not made by me) and wanted to do the switch over to ubuntu to hopefully speed up my simulations, since that version just uses 25% of my Cpu.
Now when i use the make auto command i get the following message:
Makefile:456: *** 'Could not compile a simple MPI example. Test was done with MPI_INC="" and MPICXX="mpicxx"'
I tried setting the MPICXX_USR to my mpi folder and tried setting CXX_USR=icpc, nothing changed.

Hi
Hi
what is your OS version?
Not sure I guess it seems to be an issue related to the compilation of mpi
Probably you can check
mpicxx --version
and
whereis mpicxx
It might give you something to looked upon
Thank you
Happy learning!

Found the solution... the mpi
Found the solution... the mpi install was broken. Reinstalled it and liggghts now compiled successfully.
