Error building sage-10.7 on Fedora 43

[Domingo Gómez]

Dear all,

First of all, thank you to the community for providing Sage and its kernel.

I am having trouble building SageMath 10.7 from source. My system is Fedora 43, fully updated  and I am trying to build Sage in a virtual environment with python3.11.

I installed gcc-12 with Homebrew and installed several libraries on my system. I am attaching my config.log and ppl-1.2.p1.log. The ppl library was installed through Homebrew.

Any help or suggestions would be greatly appreciated.

We don't support Linuxbrew, so you are on your own here.
Fedora 43 does have up to date ppl-devel package, so it might be easier to use.
Our latest betas support gcc 15, and the easiest way to build Sage on Fedora 43
would be to go with
https://github.com/sagemath/sage/archive/refs/tags/10.8.beta9.tar.gz

[Domingo Gómez]

Thank you for your response.

If Linuxbrew is not supported, then I will build it with the packages from Fedora.

I trying the same, but not the error is different.

The easiest fix for this would be

sudo dnf install python3.13-devel python3.13

and then, after removing

/home/gomezd/Git_Repositories/sage-10.8.beta9/sagealpha/bin/
/home/linuxbrew/.linuxbrew/bin/

from your PATH

run

./configure --with-python=python3.13 && make

sage-10.8.beta9 builds on Fedora 43 for me, fwiw

[enriqu...@gmail.com]

It builds for me also but all tests fail with lib problems. Building with python3.13 does not work since python3.13-setuptools is missing.

[Domingo Gómez]

Dear all, 

I wanted to thank you all of you, sage is working. Thanks Dima and Volker for your help.

[Dima Pasechnik]

Hi Domingo,
we wonder what exactly you did to install on Fedora 43 with Python
3.13. Cause we have problems.

[Domingo Gómez]

I might had to use python3.13 -m pip install --upgrade pip setuptools 

I don't remember more than that.

right - and this is "safe", in the sense that python3.13 isn't the
"normal" system python (which is 3.14.0 in this case)

I suppose we should mention this in release notes.

Thanks for the tip, but it is not enough to me. I get: /usr/bin/python3.13: No module named pip

[enriqu...@gmail.com]

I downloaded get-pip.py and installed pip. It's building now. Thanks!
