[Slackbuilds-users] lirc for Slackware 13.1 not building on x86

[Omari Norman]

Hi,

When I try to build lirc on x86 for Slackware 13.1, I get this error:

make  all-recursive
make[1]: Entering directory `/tmp/SBo/lirc-0.8.6'
Making all in drivers
make[2]: Entering directory `/tmp/SBo/lirc-0.8.6/drivers'

It seems the problem is that a Makefile in /usr/src/linux-2.6.33.4 is
trying to include a file that does not exist because there is no
directory for i486. This patch makes it compile by simply saying,
compile it for i386. I have no expertise whatsoever so I can't vouch for
how good the patch is or whether others should use it, but it does work
for me.

Thanks for doing the work of making lirc work with the new kernel;
without this SlackBuild I probably could not use 13.1 at all. --Omari
