The version numbers in PKGBUILD and .SRCINFO differ which leads to, e.g., aurutils attempting to re-build micromamba on every run. Could you bump both values to a common version?

@bcb, Thanks for catching that! Updated version has been pushed.

I can't build this in a clean chroot (using aurutils) as prepare() tries to use relative paths for the patches. Please replace these with

  patch -p0 -i "${srcdir}/static-off.patch"
  patch -p0 -i "${srcdir}/utils.cpp.patch"

to ensure the patches can be found :).

it does, thank you!

@flying-sheep, The latest version should have all of those issues resolved.

Hi, you don’t actually install libmambapy. building it is ON, but it’s not on my system!

Please fix or stop conflicting with python-libmamba and providing python-libmambapy

That looks like an issue specific to your local environment (i.e., "/home/arthur/.local/bin/ctest").

Micromamba installs without the need for python-cmake in a fresh Docker container: https://github.com/brianrobt/micromamba-aur/blob/master/Dockerfile

I had to install python-cmake (python-cmake-bin) to be able to build it.

Just published the new version. Please let us know if there are any issues!

I just got a working patch for the fmt changes which can be seen below. Since I'm not the maintainer of this package, I can't push the changes.
