pwc module fails to build, unable to compile, missing linux/config.h [Feisty/Gutsy]

[jfjellstad]

Binary package hint: pwc-source

pwc-source won't compile. When compiling with make-kpkg modules_image, pwc package doesn't get created (other modules, like the nvidia package gets created).

When running rules manually, I get the following error:
liem@minerva:/usr/src/modules/pwc$ debian/rules
dh_testdir
rm -f build-arch-stamp build-indep-stamp configure-stamp
# Add here commands to clean up after the build process.

Sorry, forgot. Running latest Dapper.
pwc-source:
  Installed: 10.0.7-3
on i386

Hello, sorry for the late response.

Is the issue still present in latest Dapper ? What about Edgy ?

[jfjellstad (john-ubuntu-fjellstad)]

I'm currently using Edgy. When compiling now, I get the following error:

Hi jfjellstad,

Any news on Feisty or Gutsy?

[Olivier Cortès (olive)]

Hi,

on Gutsy *and* Feisty, build error too :

See /var/cache/modass/pwc-source.buildlog.2.6.20-16-generic.1190300883 for details.
Build failed. Press Return to continue...

linux-headers-`uname -r` is installed on both machines (gutsy and feisty), and module-assistant fetched anything normally needed to compile modules (kqemu and alsa just build, install fine and work perfectly). I suspect this to be a newbie error as linux/config.h has been a standard file in the past, but I can't remember where to find it.
Is it just as simple as `gunzip -cd /proc/config.gz > /usr/include/linux/config.h` (as root) ?

What do you think about it ? Why does pwc needs this linux/config.h whereas other modules compile fine without it ?

Fix for Gutsy on the way to the archives.

[Philipp Kern (pkern)]

pwc (10.0.12-rc1+final-2ubuntu1) gutsy; urgency=low

  * Removed `struct pt_regs *regs' from pwc_isoc_handler's signature
    in `pwc-if.c' (throws a warning about an incompatible pointer type).
  * Removed `#include <linux/config.h>' from `pwc.h' (fixes a
    compilation error when module-assistant is invoked on the module).
    (LP: #46956)
  * Modify Maintainer value to match the DebianMaintainerField
    specification.
  * Do not ignore failures on clean.

I am experiencing the same problem running Gutsy.

When is this bug likely to get fixed?
