+ 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
+ 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.
+ 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_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'.
+ DEBUG
+ if set to 'true', debugging messages will be sent to the syslog
+ as udev is run. Default value is 'false'.
+
+ So, if you want to build udev using klibc with debugging messages, you
+ would do:
+ make USE_KLIBC=true DEBUG=true
+
+ Note: If you want to use klibc, you will have to set up the "linux"
+ symlink properly. See the file klibc/klibc/README and pay
+ attention to step "a)" there.
