Hello, I tried to run step-18 and initially received the following error message:
Error! This tutorial requires a deal.II library that was configured with the following options: DEAL_II_WITH_MPI = ON DEAL_II_WITH_PETSC = ON DEAL_II_PETSC_WITH_COMPLEX = OFF However, the deal.II library found at /home/krishanu/Google_Drive/dealii/dealii_920/library_dealii_920 was configured with these options DEAL_II_WITH_MPI = OFF DEAL_II_WITH_PETSC = OFF DEAL_II_PETSC_WITH_COMPLEX = which conflict with the requirements. So, I used the following commands (from this link: https://www.dealii.org/current/external-libs/petsc.html) to install PETSC: tar xvzf petsc-x-y-z.tar.gz cd petsc-x-y-z export PETSC_DIR=`pwd` export PETSC_ARCH=x86_64 ./config/configure.py --with-shared=1 --with-x=0 --with-mpi=1 --download-hypre=1 make make test Then used the following commands to build, configure and install deal.ii mkdir build cd build cmake -DCMAKE_INSTALL_PREFIX=/path/to/install/dir ../deal.II But it seems that deal.ii did not auto detect PETSC and MPI as it showed the following among other configured features: Configured Features (DEAL_II_ALLOW_BUNDLED = ON, DEAL_II_ALLOW_AUTODETECTION = ON): # ( DEAL_II_WITH_MPI = OFF ) # ( DEAL_II_WITH_PETSC = OFF ) I am wondering what I might be missing here. Could anyone please help? -- 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.
