Hi Guillermo,

I haven’t had a chance to investigate this in any detail yet but I note that you seem to be using Fedora 35 and a fairly out of date source release of Nektar++ 5.0.3?

I seem to recall that there were some challenges building on Fedora 35 a little while ago which should be fixed in a more recent release. Have you updated your system version in recent months or you have previously built v5.0.3 on Fedora 35 successfully?

The error looks to be something related to a null pointer in one of the unit test source files so I suspect this is not directly related to Blas/Lapack - I could be wrong and would need to check in more detail.

Just looking now in the CMake error file, I also note that it looks like it can’t find mpi.h, although actually I would have though that you couldn’t start building if that wasn’t resolved, so maybe you resolved this before starting the build?

Best wishes,
Jeremy

Hi,

I have recently installed the development versions of Lapack and Blas (along with some other libraries) on my local machine. I have tried to rebuild nektar, without any modification to the make file, and it failed because of different errors. I have also tried to with a clean installation of the latest version, also without success - same error. I could not manage to find the issue. I am attaching the CMake log files as well as part of the screen output.

Some useful information:
mpirun (Open MPI) 4.1.1
cmake version 3.24.2
g++ (GCC) 11.3.1 20220421
Package lapack-devel-3.10.1-1.fc35.x86_64 is already installed.
Package lapack-3.10.1-1.fc35.x86_64 is already installed.
Package blas-devel-3.10.1-1.fc35.x86_64 is already installed.
Package blas-3.10.1-1.fc35.x86_64 is already installed.

Any help will be appreciated.

Thank you
Guillermo
