LIRC kernel modules source for DEBIAN
=====================================
By default, debian/rules will set the kernel-specific options from the
kernel source tree in /usr/src/linux.
You need to have a complete linux source tree for your kernel, not just an
up-to-date kernel image, to compile the LIRC drivers. The LIRC modules
contain some references to kernel source files.
To recompile the LIRC kernel modules:
If you are using make-kpkg:
0) Make sure you have installed kernel-package.
1) Unpack /usr/src/lirc-modules.tar.gz into your working directory.
!!WARMING!!
If you use same working directory where an old version of the source
is put, then you remove the old source before extracting this new
source.
2) Go to the the base of the kernel source tree (usually the
/usr/src/linux directory).
3) To build the LIRC modules, execute:
make-kpkg --revision number modules_image
where number is the same revision number used to build the
kernel-image package in the previous step. This will generate a
lirc-modules-<kernel version> deb file in the parent directory.
MODULE_LOC environment variable specifies a top directory
where kernel module sources you want to build are put.
For example, if you want to build LIRC and the source
are put in ~/modules/lirc/, then you need to
set MODULE_LOC="~/modules".
All settings can be set in /etc/lirc/lirc-modules-source.conf or
via debconf (debconf is preferred):
dpkg-reconfigure lirc-modules-source
4) Install the newly created deb file (you can use `dpkg -i file').
If you are not using make-kpkg:
If your kernel is compiled with CONFIG_MODVERSIONS enabled, for kernel
symbol version checking, /usr/include/linux/modversions.h (the symbol
version database) will be required. This is created by running `make dep'
(in addition to `make config) in the kernel source tree.
1) Ensure that the kernel source tree is in the /usr/src/linux
directory and ensure that it is configured (execute `make config
dep' in the /usr/src/linux directory).
2) Go to the lirc root directory.
3) Execute as root (or fakeroot) `debian/rules binary-modules'. This
will generate an lirc-modules-<kernel version> deb file in the
parent directory.
You must manually set KDREV environment variable, which specifies
the Debian kernel revision on which this LIRC modules package
depends. For example, if the Debian revision of the kernel package
is Custom.1, the proper command would be
debian/rules KDREV=Custom.1 binary-modules
The LIRC modules package will have a recommendation of
kernel-image-<kernel version> (= Custom.1)
Note: The location of the kernel source tree may be specified by
supplying the KSRC variable as a command line option. For example, if
the kernel source is located in /usr/local/src/kernel-2.0.0, the
proper command would be
debian/rules KSRC=/usr/local/src/kernel-2.0.0 binary-modules

by Masato Taruishi <taru@debian.org> which itself is almost an exact copy of
the documentation for the pcmcia packages made by Brian Mays <brian@debian.org>.
