Dear Firedrakers, Running the install script $ python firedrake-install --no-package-manager --disable-ssh --honour-pythonpath gave me the following error: Could not find a functional BLAS. Run with --with-blas-lib=<lib> to indicate the library containing BLAS. Or --download-fblaslapack=1 to have one automatically downloaded and installed But the download option does not seem to be a recognised command for the install script $ python firedrake-install --no-package-manager --disable-ssh --honour-pythonpath --download-fblaslapack=1 firedrake-install: error: unrecognized arguments: --download-fblaslapack=1 Thanks Will
