V4L/DVB building procedures are based at the use of Makefile rules.
|
|
Those rules are close to the ones at Linux Kernel, to allow an easier
|
|
usage.
|
|
|
|
=======================================================================
|
|
Quick building procedure is:
|
|
make all
|
|
======================================================================
|
|
|
|
For those who may want more than just build all stuff there are some
|
|
other interesting parameters to make:
|
|
|
|
======================
|
|
Normal building rules:
|
|
all - build all modules
|
|
|
|
clean - Cleans compiled files from the tree,
|
|
but keeping the latest
|
|
used configuration and kernel version
|
|
|
|
distclean - Cleans compiled files from the tree,
|
|
latest used configuration and kernel
|
|
version.
|
|
|
|
default - Continues building the latest module selection
|
|
This is the behavior when just typed:
|
|
make
|
|
|
|
install - Installs all modules at kernel's default dir
|
|
for V4L/DVB. Requires root access.
|
|
|
|
man_install - Install V4L2 API man pages.
|
|
|
|
rminstall - cleans previous installations of V4L/DVB modules
|
|
|
|
sound-install - installs the sound modules related to V4L/DVB
|
|
tree.
|
|
|
|
======================
|
|
Firmware rules:
|
|
|
|
firmware - Create the firmware files that are enclosed at the
|
|
tree.
|
|
Notice: Only a very few firmwares are currently here
|
|
|
|
firmware_install- Install firmware files under /lib/firmware
|
|
|
|
======================
|
|
Documentation rules:
|
|
spec - Creates both V4L and DVB API specification
|
|
|
|
man - Creates V4L2 API man pages
|
|
|
|
=======================
|
|
Module selection rules:
|
|
(Those may require write access to kernel tree)
|
|
|
|
allmodconfig - Called by make all. Selects all modules that are known
|
|
to compile against the kernel version used.
|
|
|
|
xconfig - Generate a xconfig menu. Requires full
|
|
kernel source, since it depends on kernel's
|
|
qconf stript;
|
|
|
|
gconfig - Generate a qt menu. Requires full
|
|
kernel source, since it depends on kernel's
|
|
gconf stript;
|
|
|
|
config - Generate a text-mode menu. Requires full
|
|
kernel source, since it depends on kernel's
|
|
conf stript;
|
|
|
|
menuconfig - Generate a ncurses menu. Requires full
|
|
kernel source, since it depends on kernel's
|
|
mconf and lxconfig stripts;
|
|
|
|
release - Allows changing kernel version.
|
|
Typical usage is:
|
|
make release VER=2.6.12-18mdk
|
|
(to force compiling to 2.6.12-18mdk)
|
|
(This will work only if
|
|
/lib/modules/2.6.12-18mdk/build/
|
|
points to that kernel version)
|
|
Or
|
|
make release DIR=~/linux-git
|
|
(to force using kernel at a specific dir)
|
|
To use current kernel version instead:
|
|
make release
|
|
|
|
======================
|
|
Module handling rules:
|
|
(require root access)
|
|
|
|
insmod - inserts all modules from V4L/DVB tree
|
|
|
|
rmmod - removes all modules from V4L/DVB tree
|
|
|
|
reload - removes then reinserts all modules
|
|
|
|
===================
|
|
Tree merging rules:
|
|
|
|
ivtv - enable merged ivtv build, using the latest ivtv sources
|
|
from ivtvdriver.org (requires subversion)
|
|
|
|
cx88-ivtv - enable cx88-blackbird ivtv API emulation
|
|
|
|
ivtv-update - update ivtv sources from ivtvdriver.org
|
|
|
|
==========================================
|
|
Patch preparation and tree handling rules:
|
|
(used by developers)
|
|
|
|
kernel-links - Generate links to V4L/DVB at kernel tree.
|
|
Requires write access to kernel tree.
|
|
|
|
cardlist - Updates Documentation/video4linux/CARDLIST.*
|
|
|
|
update - updates the tree from master repository
|
|
|
|
commit - commits the change, asking for a commit msg
|
|
|
|
push - sends outgoing stuff to master repository
|
|
|
|
checkemacs - checks codingstyle and reports to emacs
|
|
using "make checkemacs" at emacs compile menu,
|
|
will report the lines with errors inside emacs.
|
|
|
|
checkpatch - checks codingstyle and reports using the same
|
|
format as c. This way, c error parsers will
|
|
handle it.
|
|
|
|
checkterse - checks codingstyle and reports using terse
|
|
syntax, used on several compilaton tools.
|
|
|
|
mismatch - checks for linker section mismatch. In other words,
|
|
check if some driver has functions not properly
|
|
declared with __init/__exit, and similar tags.
|
|
It will also be more pedantic by dealing with
|
|
compilation warnings as if they are errors.
