I am not able to build the scipy spkg with 10.8beta5 on macOS arm. The
build fails with a bogus error like "fortran compiler cannot generate
code". I say it is bogus because (a) the same gfortran worked fine to
build openblas and (b) it also works fine to build scipy if I set my PATH
to include sage/local/bin and run `pip wheel .` in the scipy spkg src
directory. But if I follow the recommended procedure to setup the sage
build environment and change to the scipy src directory then running bash
spkg-install fails with the same bogus error about gfortran. So some
variable is being set in the sage build environment that breaks gfortram.
I thought I might be able to build the wheel and install it with Sage's pip
and then use configure args -enable-system-site-packages and
-with-system-scipy=yes. (My "system" is located in sage/local/lib.). That
appeared to work. The config.log says:
real_configure:92110: will use system package and not install SPKG scipy
However, that turns out to be a lie. When I run make build it tries to
build the scipy spkg, anyway and that fails with the same bogus error.
Any insights would be very welcome!
