@boegel Can you tell me what is the problem?

@hajgato It looks like that it also needs sundials. Right now it is downloading it from computation.llnl.gov and when attempting to build it it fails with:

./install: line 20: cd: too many arguments

Ideally we would want to build it externally and add it as a dependency.

@vanzod The problem is that Nek5000 uses a bunch of external dependencies (gslib 1.0.1, SUNDIALS 2.7.0, Hypre 2.11.2, netCDF 4.4.1.1, exodus), some of them with special config. So originally I have decided to use the download and build locally approach. Not sure that other versions are working or not with Nek5000, so we might have some version clashes within the toolchain. So I would rather solve the problem by patching then adding SUNDIALS as a dep. The problem is that debian gives an error to cd sundials-2.7.0/ sundials-2.7.0.tar.gz meanwhile RHEL will change to the directory.
