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
