Hi! I had to add (...) CFLAGS="-I/usr/include/wcslib-7.4/" pip wheel (...) to make gcc see wcs.h. Perhaps it will help someone :)

@petronny is correct. python-pip needs to be in makedepends

Please add python-pip to makedepends.

I got the error quoted below while trying to update the package. The solution was simply to mount the tmp-filesystem with exec instead on noexec. Maybe it could be checked to have a executable filesystem for building.

Best regards, Jan

Missing makedepends python-pip

The default of makepkg is MD5. I have updated to SHA512. As for the second point, this is an issue with makepkg that will be fixed with the next version of pacman. If you want to silence the message, just define a PACKAGER environment variable in the indicated format.

When building python-astropy 3.2.3-1:

==> Validating source files with md5sums...

Please use at least sha256sums.

==> WARNING: PACKAGER should have the format 'Example Name <email@address.invalid>'

Please provide a PACKAGER variable in the PKGBUILD file.

3.2.2 released. And the new version of wcslib seems to be compatible with astropy now, so you can use the external one with --use-system-libraries again.

The package has been updated to 1.1.2. Sorry for the delay. The minimum wcslib version got bumped with astropy 1.1.2 in order to fix a critical bug. In the end the AUR astropy package depended on the Arch wcslib package update.

Thank you, this way it still throws a couple of warnings but goes all the way through.
