wl kernel module

[Tristan Hill]

Hi,
I trying to find the most robust way to use wl kernel module.
Initially I installed the wl-kmod package but this didn't seem to cause
the package with the actual module to be installed
(kmod-wl-3.19.3-200.fc21.x86_64.x86_64).  The description of the kmod-wl
indicates it should require the package for the latest package but I do
not see this:
$ rpm -qR kmod-wl
akmod-wl = 6.30.223.248-7.1.fc21
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(FileDigests) <= 4.6.0-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
rpmlib(PayloadIsXz) <= 5.2-1

Manually installing the package works but I guess will not survive a
kernel upgrade.

Next I looked at akmods-wl.  yum install akmods-wl does not seem to
trigger a module build.  Then I tried:
$ sudo akmods --akmod wl
Checking kmods exist for 3.19.3-200.fc21.x86_64            [  OK  ]
Files needed for building modules against kernel
3.19.3-200.fc21.x86_64 could not be found as the following
directories are missing:
/usr/src/kernels/3.19.3-200.fc21.x86_64/
/usr/lib/modules/3.19.3-200.fc21.x86_64/build/Is the
correc[FAILED]-devel package installed?

So no kernel-devel package installed.  The akmods package appears depend
on kernel-devel-uname-r but kernel-devel wasn't installed on my system.
Now I've manually installed it and the command above works.  Lets see
what happens on next kernel upgrade.

Could someone advise whether the above some like bugs or whether I'm
doing something wrong?

Cheers
Tristan
