I removed the pybind11 patch and built 2.3.3.alpha0 with the additional dependency python-scikit-build-core

However, it fails to find libmambaConfig.cmake when building the wheel.

Good news! They added pybind11>=3 support!

We now apply the patch and it seems to work! https://github.com/mamba-org/mamba/pull/4059

Hmm, doesn’t seem to work for me anymore.

seems like the cmake --install build --prefix install line is missing, also it should be -Dlibmamba_ROOT=$PWD/../../install.

OK, there were a few issues, but I fixed them. Now this works:

# downgrade pybind11 to fulfill makedep
paru -U --asdeps /var/cache/pacman/pkg/pybind11-2.13.6-2-any.pkg.tar.zst
# build and install
makepkg -i

Thanks! It feels as if upstream picked up on the issue you filed (there’s an active pull request), I guess this will be fixed soon :)

yes, first paragraph of the comment I made before yours. pybind11 3.

you need to downgrade pybind11 to 2.x before building for now.

I run into this compilation error:

Do you have any tips what this could be cause by?

flying-sheep commented on 2025-07-25 11:22 (UTC) (edited on 2025-07-25 11:33 (UTC) by flying-sheep)

the issues are because of pybind11 3.0: https://github.com/mamba-org/mamba/issues/4024

with pybind11 2.x installed, we just need to modify package() to have a cd ${_pkgname}-${pkgver} before the install -Dm 644 LICENSE … and everything works:
