no problem ^^

@Nep_Nep thank you very much, I did not had time to investigate the errors my self.

from https://github.com/madler/zlib/issues/856#issuecomment-1749514906 seems to fix it, the .so is created and android-aarch64-qt6-base can be linked against it

This seems related to what Martchus sent regarding the error, from $SRCDIR/zlib-1.3/configure.log

I'd rather update the package in accordance with the regular zlib package which also has a few other changes, see https://gitlab.archlinux.org/archlinux/packaging/packages/zlib/-/commits/main.

Had to apply this patch:

For shared library building need to apply this commit (currently on 'develop' branch): https://github.com/madler/zlib/commit/05796d3d8d5546cf1b4dfe2cd72ab746afae505d

BTW, 'export CXX' and 'case "$_android_arch" in' is excessive in current PKGBUILD.

Yes, the build system somehow determines that building the shared library is not supported:

Maybe I can come up with a fix and maybe it is even an upstream bug.

I'm currently not using the package so I'm also not trying to rush a fix. (I suppose if the Qt 6 ecosystem matures, e.g. if Kirigami is ported, I'll look into Android + Qt 6 more actively again.)

The shared library is enabled but isn't building it, in previous versions it worked fine, its maybe a bug of this version, just send me the patches to fix it, I'm quite busy right now to work in this.

Looks like the shared library is missing in the latest update. Is this intended? I have currently several packages in my repository using the shared library which I needed to rebuild. However, linking each of those shared libraries statically against zlib is likely not the best solution so it would make sense to keep the shared library. Of course the same counts for the other archs.
