Hi Oliver, It seems that your eigen is at "/Users/os3918/Documents/eigen-3.3.3.tgz", but Firedrake still tells PETSc that eigen is at "/Users/os3918/Documents/firedrake/src/eigen-3.3.3.tgz"; this path is hard-coded here https://github.com/firedrakeproject/firedrake/blob/master/scripts/firedrake-.... I think the easiest solution is, using your failed installation, to move eigen-3.3.3.tgz to "/Users/os3918/Documents/firedrake/src", activate firedrake venv, and run `firedrake-update --rebuild` (using unmodified install script). Thanks, Koki ________________________________ From: firedrake-bounces@imperial.ac.uk <firedrake-bounces@imperial.ac.uk> on behalf of Ollie Street <olliestreet@outlook.com> Sent: Thursday, November 25, 2021 11:13 AM To: firedrake <firedrake@imperial.ac.uk> Subject: [firedrake] Installation issue Hi, I’m still attempting to get a stable version of firedrake installed on my MacBook, I have encountered an issue with PETSc. It first hit an issue with the file 'eigen-3.3.3.tgz’, so I downloaded this separately and modified the installation file to point it towards this. The installation seemingly got over this issue, but returned the following error on the command line. I’ve also attached the install log. Any help would be much appreciated! Best, Oliver Depending on your platform, PETSc may take an hour or more to build!
