Hi users, I have a problem installing Firedrake with Petsc. Initially install using the following steps: curl -O https://raw.githubusercontent.com/firedrakeproject/firedrake/master/scripts/... unset PYTHONPATH; unset PETSC_DIR; unset PETSC_ARCH; python3 firedrake-install and it works on installation, only when testing my code with the discontinuous Galerkin hybrid method (HDG) it gave the following error: (firedrake) hpc@hpc:~/Downloads/Exemplos_Firedrake/HDG/poroso/MWE/SDHM$ python3 sdhm_monolithic.py Traceback (most recent call last): File "sdhm_monolithic.py", line 1, in <module> from firedrake import * File "/home/hpc/firedrake/src/firedrake/firedrake/__init__.py", line 8, in <module> raise ImportError("PETSC_DIR is set, but you did not install with --honour-petsc-dir.\n" ImportError: PETSC_DIR is set, but you did not install with --honour-petsc-dir. Please unset PETSC_DIR (and PETSC_ARCH) before using Firedrake. try installing with python3 firedrake-install --honor-petsc-dir, but I have the following error: hpc @ hpc: ~ $ python3 firedrake-install --honor-petsc-dir Running firedrake-install --honor-petsc-dir The --honor-petsc-dir is set, but PETSC_DIR environment variable is not defined. If you have compiled PETSc manually, set PETSC_DIR (and optionally PETSC_ARCH) variables to point to the build directory. could you help me on how to solve that problem, please.
