Working PKGBUILD and patch for broadcom-wl on kernel 3.14.2

README.md

Thanks

to Krejzi bricewge for posting the patch.

The gcc.patch is from a working source tarball that bricewge posted on broadcom-wl-dkms, but I found the patch works for the broadcom-wl as well.

Why

The broadcom-wl (AUR) module does not build against linux kernel 3.14.2, the latest update in Arch.

How

To apply the patch, download the broadcom-wl.tar.gz, and unpack it somewhere.

 tar -xvzf broadcom-wl.tar.gz

Replace the PKGBUILD in that directory with the one that's part of this gist.

Then, put the gcc.patch into the same directory as the PKGBUILD.

Running makepkg -s to build the broadcom-wl module should now be fine.
