10 months ago The primary error is that your Fortran compiler does not seem to work. In principle you can use PyClaw without the Fortran compiler but I am not sure how the meson build handles that.

10 months ago I found someone had a similar issue here:
https://github.com/mesonbuild/meson/issues/12282
They were also using homebrew to install gfortran, and it sounds like there is a bug with some particular version of gfortran. From the thread there, you could try doing
export LDFLAGS="$LDFLAGS -Wl,-ld_classic"
before the clawpack install. If that doesn't work, I suggest installing a different fortran compiler. I recommend using one from this site:

10 months ago I have not had to do anything special on my macs. Probably I reinstalled gcc/gfortran from brew after the upgrade to clang15, you should try that.
You can also create a conda env, install gfortran via conda inside that env, and then pip install clawpack.
Hi, I'm trying to install clawpack using 'pip install clawpack' and I get the error message below. Do you know what might be wrong and how to fix it?
