As of 2018-06-11 all build issues have been resolved and package is working as expected.

I cannot build it on the latest Arch Linux:

Could you help me to solve that? Thanks.

.. and what for is e.g. perl needed, when I just want to build the kernel module?

The Arch Wiki has instructions on how to handle git submodules: https://wiki.archlinux.org/index.php/VCS_package_guidelines#Git_Submodules

The prepare()-function invokes a lot of data traffic (via initialisation of git submodules).

For getting sources, the source-array is the place to go.

Is it possible to make all the downloads via the source-array? Would be much more convenient, expecially over slow internet connections where downloading via source-array can be managed differently e.g. by specifiying handlers in the makepkg.conf.

Package updated - Added new dependencies libpng, libtiff, glu, cairo, libbsd, python2, and linux-headers

thanks @tgc

I found that in a headless install it now requires OpenGL libraries.

I tried building this pkg on a very fresh Arch install and had to install the following additional dependencies (some probably overlap) to successfully build it: llvm libpng mesa cairo libtiff libbsd python2 linux-headers

As of 2018-06-11 all build issues have been resolved and package is working as expected.

Thank you for your work on this @Xorg . I will try my best to keep this package updated.

Hello world.
I have written this PKGBUILD 4 years later, and today I'm tired of maintening this package: there are often upstream breaks, and it requires a lot of time to build and fix this package.
Since 4 years, I was trying to do my best to offer to Arch users a buildable Darling out of the box, but Upstream seems not ready yet for packaging.
Some issues remain: the package is installed under /usr/libexec, but due to Arch standards, it should not [1]. There are some hacks, like the darling-git.install file and the DKMS sub-package. Sometimes, DKMS fails, but it works after reinstalling the darling-mach-dkms-git package.
I'm not interested to maintain this package anymore. Feel free to adopt it and improve it. Good luck to next maintener.

@Xorg: Great! it work for the problem..
but now i found another problem..
