 |

In case anyone else was getting difficulties with lirc and the mceusb2 controller and kernel 2.6.20 I have finally found a solution so that lirc will compile
Check out
http://www.mail-archive.com/linux-kernel%40vger.kernel.org/msg116981.html for the mceusb2 patch
Using this will remove all the SLAB_ATOMIC errors which prevented compilation
I did the following:
| Code: |
ebuild /usr/portage/app-misc/lirc/lirc-0.8.1.ebuild fetch
ebuild /usr/portage/app-misc/lirc/lirc-0.8.1.ebuild unpack
cd /var/tmp/portage/app-misc/lirc-0.8.1/work/lirc-0.8.1/drivers/ |
Then being a bit short in the head about patching, I applied the patch by hand.
It seems to me that it just replaces any occurrence of SLAB_ with GFP_
So fire up your editor/patch commands and modify
then finish off with
| Code: |
ebuild /usr/portage/app-misc/lirc/lirc-0.8.1.ebuild compile
ebuild /usr/portage/app-misc/lirc/lirc-0.8.1.ebuild install
ebuild /usr/portage/app-misc/lirc/lirc-0.8.1.ebuild qmerge |
HTH anyone else in the same predicament
