Arch Linux User Repository

For those trying to build on Linux 5.1 please see this PR

https://github.com/darlinghq/darling-newlkm/pull/5

I have just included this patch in the most recent package.

When building it requires linux-headers on my system. But I run linux-zen instead. Can I safely ignore this dependency?

@dreieck & @J5lx, I have updated the PKGBUILD placing the git submodules into the sources section. Thanks for the info!

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
