Rohit,
Thank you responding to my posting.
I attempted to do a 'meson' build. The build failed. The commands I used
follow:
echo f2py build for divapy
echo deleting previous build
rm -i *.so
rm -i divapy.f
rm -i divapy-f2pywrappers.f
rm -i divapymodule.c
echo concatenating files
cat *.f > divapy.f
echo building Python wrappers using meson
/Users/user/opt/anaconda3/bin/python -m numpy.f2py divapy.f -m
divapy --lower
meson --wipe builddir
meson setup builddir
meson compile -C builddir
cd builddir
/Users/user/opt/anaconda3/bin/python -c 'import divapy'
echo done.
The meson log file is attached for reference. The output written to the
terminal is:

In doing a deeper dive, I found that I have meson installed under Homebrew.
Before I open an issue, I'd like to know do I need to have meson and/or
meson-python installed under Anaconda?

More of a workaround, since it seems like the wrappers and binding
files are generated could you try the `meson` build following this
page in the documentation?
https://numpy.org/devdocs/f2py/buildtools/meson.html
`distutils` support is patchy at best, but if the meson build doesn't
work the bindings might be incorrect, please open an issue in that case.

*Subject:* [Numpy-discussion] How to get numpy.distutils.fcompiler to
find my absoft compiler
Hello everyone,
I'm trying to wrap some Fortran77 subroutines from the Math77 library
using f2py3. f2py3 responds with a message:
File
"/Users/user/opt/anaconda3/lib/python3.9/site-packages/numpy/distutils/fcompiler/__init__.py",
line 426, in get_version
raise CompilerNotFound()
numpy.distutils.fcompiler.CompilerNotFound
I'm running Python ver. 3.9.17 under the Anaconda distribution
(anaconda Command line client (version 1.12.0)) on a Mac Pro (2019) under
Mac OS X Ventura ver. 13.4.1. The Fortran compiler is Absoft Pro
Fortran ver. 22.0.
The set of subroutines to be wrapped were concatenated into a single
file named divapy.f. The command used to wrap the routines was
--fcompiler=absoft --f77exec=/Applications/Absoft22.0/bin/f77
-c -m diva divapy.f
I've attached a file containing the complete set of messages output by
f2py3 using the command above.
Any suggestions as to how to fix this problem?
Sam Dupree.
