Directories and installation variables

Yocto Project Openembedded directories installation variables

The following table provides a list of the variables that are used to control the directories into which files are installed.

These variables can be used directly by the recipe to refer to paths that will be used after the package is installed.

Variable name           Definition                 Typical value
---------------------   ------------------------   --------------------
prefix                  /usr                       /usr
base_prefix             (empty)                    (empty)
exec_prefix             ${base_prefix}             (empty)
base_bindir             ${base_prefix}/bin         /bin

datadir                 ${prefix}/share            /usr/share
sysconfdir              /etc                       /etc
localstatedir           /var                       /var
infodir                 ${datadir}/info            /usr/share/info
mandir                  ${datadir}/man             /usr/share/man
docdir                  ${datadir}/doc             /usr/share/doc
servicedir              /srv                       /srv
bindir                  ${exec_prefix}/bin         /usr/bin
sbindir                 ${exec_prefix}/sbin        /usr/sbin
libexecdir              ${exec_prefix}/libexec     /usr/libexec
libdir                  ${exec_prefix}/lib         /usr/lib
includedir              ${exec_prefix}/include     /usr/include
palmtopdir              ${libdir}/opie             /usr/lib/opie
palmqtdir               ${palmtopdir}              /usr/lib/opie
systemd_unitdir         ${systemd_unitdir}         /usr/lib/systemd
systemd_system_unitdir  ${systemd_system_unitdir}  /usr/lib/systemd/system
systemd_user_unitdir    ${systemd_user_unitdir}    /usr/lib/systemd/user

When specifying paths as part of the FILES variable, it is good practice to use appropriate path variables.

For example, use ${sysconfdir} rather than /etc, or ${bindir} rather than /usr/bin.

You can find a list of these variables at the top of the meta/conf/bitbake.conf file in the Source Directory.

You will also find the default values of the various FILES:* variables in this file. https://git.yoctoproject.org/cgit.cgi/poky/plain/meta/conf/bitbake.conf
