[petsc-dev] Configure --download-eigen hangs

[Pierre Jolivet]

FWIW, I’ve had the same issue as Jacob for quite a while and I’ve since been using brew install eigen to bypass this.
I’ve just checked again, and look at one of the process spawned during ./configure. That doesn’t look alright to me.

Thanks,
Pierre

This is less robust but on my setup the window bar (where the close, minimize, etc buttons are) of the terminal window also reports the currently running process and this also only shows bash. For reference when configure is running normally, the top bar switches between clang, ld, expr, cmake, g++, etc. System resources used usually shoots up to ~40-90% as it gets into the different configures and makes for each package.
