to sage-release

As always, you can get the latest beta version from the "develop" git branch. Alternatively, the self-contained source tarball is at http://www.sagemath.org/download-latest.html

Due to a hardware issue we currently can't add new tarballs to the mirrors, so either you download from source (and cross fingers that nobody swizzled isomorphic-but-not-identical tarballs) or use my server (sagepad.org) temporarily via environment variables, which roughly amounts to

./bootstrap -u http://sagepad.org/spkg/upstream/configure/
./bootstrap -d
./configure
make -j8 start SAGE_SERVER=http://sagepad.org

Happy building! ;)

Thank you for this new beta.

I'm experiencing an issue with the compilation of givaro on macOS 26.3.1, using homebrew (recently upgraded). Il a fresh shell, I did

make distclean

./bootstrap -u http://sagepad.org/spkg/upstream/configure/
./bootstrap -d

source .homebrew-build-env
./configure --enable-system-site-packages --with-python=`which python3.13` --with-system-jupyter_core=no --with-system-platformdirs=no --enable-tdlib=yes --disable-notebook --with-darwin-accelerate=yes

make -j8 start SAGE_SERVER=http://sagepad.org

and I get several errors in the compilation of givaro. See attached logs.

Any help is more than welcome.

Best,

David.

It seems to be a known issue with llvm 21 and there is a fix https://github.com/linbox-team/givaro/pull/240.

However, it is not yet in the last release of givaro.

I don't know how I can use that to fix my compilation issue.

create a patch, as usual?
Anyhow, you can use the Macaulay2 homebrew tap:

<https://github.com/Macaulay2/homebrew-tap/blob/main/Formula/givaro.rb>

it should work for you. They use givaro from github, the master branch.

I already use Macaulay2 from homebrew

MAC-04017247:sage dcoudert$ brew search givaro

==> Formulae

macaulay2/tap/givaro ✔

This is version 4.2.1 (in directory /opt/homebrew/Cellar/givaro/4.2.1_1/).

But configure says it’s not suitable.

In fact,

- we have no homebrew.txt file in build/pkgs/givaro/distros/

- directory /opt/homebrew/Cellar/givaro/4.2.1_1/bin/ contains only givaro-config

- same for /opt/homebrew/bin/givaro-config

So I don’t know what to do.

this is only crucial for CI

it's probably related to the not yet done #41626

Something surprising is that configure outputs

-----------------------------------------------------------------------------

Checking whether SageMath should install SPKG givaro...

checking for givaro >= 4.2.0... yes

real_configure: will use system package and not install SPKG givaro

-----------------------------------------------------------------------------

And then in the summary:

givaro: no suitable system package; standard, SPKG version 4.2.1 will be installed

How is this possible ?

that's because we have a convoluted logic in spkg-configures for linbox (and/or fflas-ffpack, I need to look it up) which makes the rejection of the latter triggering the rejection of givaro.

You can undo it, it's not hard.
