- You must be running a 2.6 version of the Linux kernel.
+- Your 2.6 kernel must have had CONFIG_HOTPLUG enabled when it was built.
+
- Make sure sysfs is mounted. udev will figure out where sysfs is mounted, but
the traditional place for it is at /sys. You can mount it by hand by running:
mount -t sysfs none /sys
Note:
There are a number of different flags that you can use when building
udev. They are as follows:
- prefix - set this to the default root that you want udev to be
+ prefix
+ set this to the default root that you want udev to be
installed into. This works just like the 'configure --prefix'
script does. Default value is ''. Only override this if you
really know what you are doing.
- KLIBC - if set to 'true', udev is built and linked against the included
- version of klibc. Default value is 'false'.
- DEBUG - if set to 'true', debugging messages will be sent to the syslog
+ USE_KLIBC
+ if set to 'true', udev is built and linked against the
+ included version of klibc. Default value is 'false'.
+ USE_LOG
+ if set to 'true', udev will emit messages to the syslog when
+ it creates or removes device nodes. This is helpful to see
+ what udev is doing. This is enabled by default. Note, if you
+ are building udev against klibc it is recommended that you
+ disable this option (due to klibc's syslog implementation.)
+ USE_SELINUX
+ if set to 'true', udev will be built with SELinux support
+ enabled. This is disabled by default.
+ DEBUG
+ if set to 'true', debugging messages will be sent to the syslog
as udev is run. Default value is 'false'.
- DBUS - if set to 'true', DBUS messages will be sent everytime udev
- creates or removes a device node. This requires that DBUS
- development headers and libraries be present on your system to
- build properly. Default value is 'false'.
+ KERNEL_DIR
+ If this is not set it will default to /lib/modules/`uname -r`/build
+ This is used if USE_KLIBC=true to find the kernel include
+ directory that klibc needs to build against. This must be set
+ if you are not building udev while running a 2.6 kernel.
So, if you want to build udev using klibc with debugging messages, you
would do:
- make KLIBC=true DEBUG=true
-
+ make USE_KLIBC=true DEBUG=true
- Install the project:
make install
make uninstall
-Things are still quite rough, and it's a bit beyond proof of concept
-code. Help is very much appreciated, see the TODO file for a list of
-things left to be done.
+Things are still quite rough, but it should work properly. If nothing
+seems to happen, make sure your build worked properly by running the
+udev-test.pl script as root in the test/ subdirectory of the udev source
+tree.

+Development and documentation help is very much appreciated, see the TODO
+file for a list of things left to be done.
-If you want to build using klibc, use the Makefile.klibc file:
- - read the klibc/klibc/README file for how to set up the linux
- symlink properly.
- - make clean
- - make -f Makefile.klibc
-and marvel at the tiny binary you just created :)
-Any comment/questions/concerns please let me know.
+Any comment/questions/concerns please let me and the other udev developers
