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:
+ ./configure \
+ --prefix=/usr \
+ --sysconfdir=/etc \
+ --sbindir=/sbin \
+ --libdir=/usr/lib64 \
+ --with-rootlibdir=/lib64 \
+ --libexecdir=/lib/udev \
--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.
+ Usually /usr, prefix for man pages, include files.
--sysconfdir=
Usually /etc.
- --with-libdir-name=
- Directory name for libraries. This is not a path name.
+ --sbindir=
+ Usually /sbin, the place for udevd and udevadm.
+ --libexecdir=
+ Usually /lib/udev, the udev private directory.
--enable-debug
Compile-in verbose debug messages. Usually not needed,
it increases the size of the binaries.
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
+ 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, ...
+ Disable the build of all extras which have larger external
+ dependencies like glib, libacl, libusb, ...
The options used in a RPM spec file usually look like:
- --prefix=%{_prefix}
- --exec-prefix=
- --sysconfdir=%{_sysconfdir}
- --with-libdir-name=%{_lib}
- --with-selinux
+ %configure \
+ --prefix=%{_prefix} \
+ --sysconfdir=%{_sysconfdir} \
+ --sbindir=%{_sbindir} \
+ --libdir=%{_libdir} \
+ --with-rootlibdir=/%{_lib} \
+ --libexecdir=/lib/udev \
+ --with-selinux
The defined location for scripts and binaries which are called
from rules is /lib/udev/ on all systems and architectures. Any
-include $(top_builddir)/config.h \
-I$(top_srcdir)/libudev \
-DSYSCONFDIR=\""$(sysconfdir)"\" \

+
========
Bugfixes.
+The configure options have changed because another library needs to be
+installed in a different location. Instead of exec_prefix and udev_prefix,
+libdir, rootlibdir and libexecdir are used. The Details are explained in
+the README file.
+
Event processes now get re-used after they handled an event. This reduces
the number of forks and the pressure on the CPU significantly, because
cloned event processes no longer cause page faults in the main daemon.
- o cleanup old extras which link libudev source directly
-
- o fix configure options and libdir-name, exec-prefix, udev-prefix, libdir, ...
o enumerate: sort control* after pcm*
o add tests for kernel provided DEVNAME logic
o drop modprobe floppy alias (SUSE), it will be in the module (2.6.30)
