The tar.gz files are downloaded from nektar src. Once extracted I follow the user guide instructions to create a build directory and pull up the ccmake gui (versions of ccmake and cmake on the PC are 4.0.2 stored in /snap/bin/cmake). Only the IncNavirStokesSolver is on, with USE_MPI switched on with thirdparty builds of GSMPI and SCOTCH. When configuring a cmake warning appears regarding policy CMP0177, and when running 'make install' the following error is displayed: ~~~~ CMake Error at CMakeLists.txt:1 (CMAKE_MINIMUM_REQUIRED): Compatibility with CMake < 3.5 has been removed from CMake. Update the VERSION argument <min> value. Or, use the <min>...<max> syntax to tell CMake that the project requires at least <min> but has been updated to work with policies introduced by <max> or earlier. Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway. -- Configuring incomplete, errors occurred! make[2]: *** [CMakeFiles/gsmpi-1.2.1_2.dir/build.make:92: ThirdParty/stamp/gsmpi-1.2.1_2-configure] Error 1 make[1]: *** [CMakeFiles/Makefile2:1405: CMakeFiles/gsmpi-1.2.1_2.dir/all] Error 2 make: *** [Makefile:146: all] Error 2 ~~~~ I assume it is an error with gsmpi, however when trying to configure with MPI on without building thirdparty GSMPI, the configuring crashes stating it must be built. Any advice is most welcome.
