-Usual options for udev installed in the root filesystem are:
- ./configure
- --prefix=/usr
- --exec-prefix=
- --sysconfdir=/etc
-For 64bit multilib-installations also:
- --with-libdir-name=lib64
-For SELinux support:
+The options used usually look like:
+ %configure \
+ --prefix=/usr \
+ --sysconfdir=/etc \
+ --bindir=/usr/bin \
+ --libdir=/usr/lib64 \
+ --libexecdir=/usr/lib \
+ --with-systemdsystemunitdir=/usr/lib/systemd/system \
--with-selinux
-All options:
- --prefix=
- Prefix for man pages, include files.
- --exec-prefix=
- Prefix for libs, binaries, usually the root filesystem.
- --with-udev-prefix=
- Prefix for internal udev path names, like /dev/, /lib/udev/.
- Only useful for testing and development installations. The
- value is copied from exec-prefix, if not specified otherwise.
- --sysconfdir=
- Usually /etc.
- --with-libdir-name=
- Directory name for libraries. This is not a path name.
- --enable-debug
- Compile-in verbose debug messages. Usually not needed,
- it increases the size of the binaries.
- --disable-logging
- Disable all logging and compile-out all log strings. This
- is not recommended, as it makes it almost impossible to debug
- udev in the running system.
- --with-selinux
- Link against SELInux libraries to set the expected context
- for created files.
- --disable-extras
- Disable the build of extras with larger external dependencies
- like glib, libacl, libusb, ...

+Some tools expect udevadm in 'sbin'. A symlink to udevadm in 'bin'
+needs to be manually created if needed.
The defined location for scripts and binaries which are called

other location will break other packages, who rightfully expect
