Ok. After installing newer cmake version and making _lapack_libraries OPTIONAL, LAPACK configuration has gone fine. For PETSc, I did something dirty. I figured that FindPETSC.cmake searches for libraries in a file named petscvariables. I made my own copy of petscvariables file and modified the linker line in this file. I changed the path hints to find this file and then the rest was as expected.
The installation was successful (I had to unload apt module, see the trailing discussion here <https://groups.google.com/forum/?hl=en-GB#!topic/dealii/9IMUhsjSGZ8>). I did a cross compilation (see here <https://groups.google.com/forum/?hl=en-GB#!searchin/dealii/cross$20compilation%7Csort:date/dealii/k4ZU250SAu8/R5AJBe91BgAJ>). Instead of using a Toolchain file, I used the option -DCMAKE_SYSTEM_NAME=CrayLinuxEnvironment as mentioned here <https://cmake.org/cmake/help/v3.6/manual/cmake-toolchains.7.html#cross-compiling-for-the-cray-linux-environment>. The complete cmake invocation is as below. cmake_new=~/bin/cmake-3.16.4/usr/local/bin/cmake $cmake_new -DCMAKE_INSTALL_PREFIX=~/bin/dealii-9.1.1/ \ -DWITH_64BIT_INDICES=ON \ -DCMAKE_PREFIX_PATH=/opt/cray/pe/lib64 \ -DWITH_MPI=ON \ -DMPI_DIR=/opt/cray/pe/mpt/default/gni/mpich-gnu/5.1/ \ -DMPI_CXX_INCLUDE_PATH=/opt/cray/pe/mpt/default/gni/mpich-gnu/5.1/include/ \ -DCMAKE_CXX_COMPILER=/opt/cray/pe/craype/2.5.13/bin/CC \ -DCMAKE_C_COMPILER=/opt/cray/pe/craype/2.5.13/bin/cc \ -DCMAKE_Fortran_COMPILER=/opt/cray/pe/craype/2.5.13/bin/ftn \ -DWITH_BLAS=ON \ -DWITH_LAPACK=ON \ -DWITH_SCALAPACK=ON \ -DWITH_PETSC=ON \ -DWITH_P4EST=ON -DP4EST_DIR=~/bin/p4est-2.2/ \ -DCMAKE_SYSTEM_NAME=CrayLinuxEnvironment \ ~/source/dealii-9.1.1 However, make test shows all tests failing with the error /bin/sh: <test name>.<release|debug>: command not found. When I navigated to tests/quick_tests and individually ran the tests, the output was as follows. $ ./lapack.debug Illegal instruction Can anyone help me with this issue? Is this because I have cross-compiled? The make test instruction was run on login node. It so, is there a way I check my installation on login node itself without needing submitting a job? -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
