building on fedora 44 (beta)

[Eric Majzoub]

Just upgraded to fedora 44 beta which ships with gcc-16.0.1. Building Sage defaults to begin building gcc-14.2.0. Can updates be made so gcc 16.x.x is OK?

Thanks,

[Dima Pasechnik]

yes, you can allow it yourself by changing
"[6-9]" to "[7-9]"
in
build/pkgs/gcc/spkg-configure.m4
line 168 and, similarity, in
build/pkgs/gfortran/spkg-configure.m4
line 89
(and run ./bootstrap after this)

[Eric Majzoub]

Thanks. With those changes Sage builds fine on Fedora 44 (beta). 

[Dima Pasechnik]

Have you run tests?
Unless there are catastrophically many failures, we should allow gcc16...

[Eric Majzoub]

It finishes running the tests but doesn't say how many failed. Below is the last bit of output from (./sage -t --all).

ChatGPT tells me to grep for "Failed example:" which turns up doctest/*.py and a few other doctest/*.rst files.

"make test" will report the errored tests, and totals.

( better, "make -jX test",  where one should replace X with the number of cores to be used)

[Dima Pasechnik]

this PR allows gcc/gfortran 16 from the system to be used

looks like you might have cut an interesting portion of the log just
above "Total time for all tests" line.

In logs/test.log you have a lot of per file entries like

[106 tests, 14.21s wall]

OK. I have attached the log file...
