[Bug 1447788] Re: Bcmwl-kernel-source doesn't compile against 4.0


*** This bug is a duplicate of bug 1424676 ***

The bcmwl kernel module couldn't build during upgrading from kernel 3.13 to 4.0.4. (the installation is looking for which I do not use). The error messages pop up during the installation of the dpkg of the .deb files for kernel 4.0.4. Actually there are error messages for all the proprietary packages, i.e. the bc43xx STA driver and the driver for nvidia-331  (I file a separate bug report for that one).

I have tried to prevent those complications by priorly installing the
build-essential package, but it did not help. Would it change something
if I was unselecting the two proprietary packages from the Software
admin prior to installing the new kernel, and then reinstalling after
rebooting under the new kernel ?

Meanwhile, what would be the most recent stable linux kernel allowing to
keep my proprietary modules ? Thank you !

  Bcmwl-kernel-source doesn't compile against 4.0

Status in bcmwl package in Ubuntu:

Bug description:
  With a 4.0 kernel provided by http://kernel.ubuntu.com/~kernel-
  ppa/mainline/v4.0-vivid/ , bcmwl-kernel-source fails to compile.
  /var/lib/dkms/bcmwl/ is attached, key
  problems excerpted below:

  /var/lib/dkms/bcmwl/ In function ‘wl_cfg80211_get_station’:
  /var/lib/dkms/bcmwl/ error: ‘STATION_INFO_TX_BITRATE’ undeclared (first use in this function)
     sinfo->filled |= STATION_INFO_TX_BITRATE;

  /var/lib/dkms/bcmwl/ note: each undeclared identifier is reported only once for each function it appears in
  /var/lib/dkms/bcmwl/ error: ‘STATION_INFO_SIGNAL’ undeclared (first use in this function)
     sinfo->filled |= STATION_INFO_SIGNAL;

  The need to run a 4.0 kernel is because the 3.19.0 kernel in Vivid will corrupt and fail on a btrfs system. Either 3.19.5 or 4.0 are required to avoid this corruption: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1445252
