Hello, I have been trying to install firedrake on our campus cluster, however I’ve had little success so far. I am not from a CS background so mostly have been googling stuff and trying different things. I am trying to make use of the modules available on our cluster, and use the PETSc already installed on the cluster. export I_MPI_CC=gcc export I_MPI_CXX=g++ export I_MPI_F90=gfortran export I_MPI_FC="$I_MPI_F90" export I_MPI_F77="$I_MPI_F90" export PETSC_CONFIGURE_OPTIONS=--download-fblaslapack export PETSC_CONFIGURE_OPTIONS=--download-scalapack export PETSC_CONFIGURE_OPTIONS=--download-mumps export PETSC_CONFIGURE_OPTIONS=--download-superlu_dist export PETSC_CONFIGURE_OPTIONS=--download-hypre curl -O https://raw.githubusercontent.com/firedrakeproject/firedrake/master/scripts/... python3 firedrake-install --no-package-manager --honour-pythonpath --honour-petsc-dir This throws exception at the following point (Also attached separately as firedrakeErrortxt) Removing existing h5py installations Installing h5py/ Installing libspatialindex Cloning libspatialindex Failed to clone libspatialindex using ssh, falling back to https.

The complete log file is also attached along with this email. Please let me know if you can be of some help, as I have received little-to-no help from the people managing the cluster. Also let me know if this is due to an error on my side while running the installer. Thank you --Bhavesh Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows 10
