Hi Folks,


I'm trying to compile OpenFOAM v1806+ on Ubuntu 20.04 and I'm running into an issue with the compilation where I get the following error:

wclean ptscotchDecomp
wmake  ptscotchDecomp
wmake ptscotchDecomp
wmakeLnInclude: linking include files to ./lnInclude
Making dependency list for source file ptscotchDecomp.C
wmkdepend: could not open 'ptscotch.h' for source file 'ptscotchDecomp.C': No such file or directory

Does anyone have any idea what might be going on here? ptscotch.h does in fact exist on the computer. They were installed using the libptscotch-dev package and are located at:

libptscotch-dev: /usr/include/scotch-int32/ptscotch.h
libptscotch-dev: /usr/include/scotch-int64/ptscotch.h
libptscotch-dev: /usr/include/scotch-long/ptscotch.h
libptscotch-dev: /usr/include/scotch/ptscotch.h

I tried adding the above directories to the path which made no difference. A log file is attached.

Thanks in advance for any suggestions or advice!

I'm having a similar issue with installing OpenFOAM v6 on Ubuntu 20.04 for Windows. Did you manage to get a solution to this?

OpenFOAM-v1806 is two years old!
In more recent versions, the handling of dpkg-architecture has greatly improved.
IMO the easier way is to install the precompiled pack for 1912 or 2006.

Hi Earl,

I've found this link useful, the problem might be a newer version of mpi. Maybe worth having a look!
