Hello everyone,

I am currently trying to install the latest version of sage locally on my laptop (Windows 11 OS) from the source code and encountered an error related to building a python package. I did the installation using cygwin. The error seems to be related to building python3-3.9.9.

I attach hereby a screenshot of the cygwin command prompt. I would appreciate any help towards solving this issue.

Best regards,

Andry

I had very similar problems when trying to install the current development version on cygwin (the package python3-3.10.2 failed to build). I was able to fix this by manually specifying in the configuration that the system python3.8 should be used (python3.9 failed for separate reasons), but then I encountered a separate bug with building e_antic-0.1.9. I could post the corresponding log files, though I should say that I have since given up on making it run on cygwin.

What I can recommend to the original poster is to set up sage locally on Windows using the Windows Subsystem for Linux, as described here:

https://doc.sagemath.org/html/en/installation/source.html#ubuntu-on-windows-subsystem-for-linux-wsl-prerequisite-installation

For me neither the BIOS modification nor the upgrade to Ubuntu 20.10 was necessary, and all steps were much faster than the steps I got to work on cygwin, too. After following the instructions above, I continued with the Ubuntu instructions on

https://doc.sagemath.org/html/en/installation/source.html#linux-recommended-installation

followed by the instructions in

https://github.com/sagemath/sage/#readme

as recommended.

Yes, many optional packages are broken on cygwin because there are not enough developers contributing to this platform. e_antic is tracked at https://trac.sagemath.org/ticket/28803

I agree with your recommendation to use WSL. In fact, in the upcoming Sage 9.6 release, this is also the official recommendation.

See the new version of the installation manual - https://6212659123a9467b3cb0cd07--sagemath-tobias.netlify.app/installation/index.html

Dear both,

Thank you for your responses. I also got another recommendation to use WSL and I am now convinced it is the better way. I should say I lack expertise in this kind of situation but wanted to install sage locally nevertheless.
