Installation on Windows Subsystem for Linux (version 3.18.5, updated 3/3/23)

[I'm currently learning how to use PETSc, so obviously the first part will be some directions on how to compile PETSc.   I'm going to start with the simplest example and then move to more complicated setups.]

Using our standard directory structure, we want to download PETSc into

mkdir ~/opt/petsc

cd ~/opt/petsc

wget https://ftp.mcs.anl.gov/pub/petsc/release-snapshots/petsc-with-docs-3.18.5.tar.gz

cd ~/opt/petsc/petsc-3.18.5

./configure --with-cc=gcc \

            --with-cxx=g++ \

            --with-fc=gfortran \

            --download-mpich \

            --download-fblaslapack

 make PETSC_DIR=$HOME/opt/petsc/petsc-3.18.5 PETSC_ARCH=arch-linux-c-debug all

Installation on Windows Subsystem for Linux (for Firedrake, under development)

sudo apt install libxml2-dev
