Common Yocto Variables

When writing Yocto recipes there are some common variables that can be used, espcially in the do_install() section

An example of this would be:

do_install() {
  install -d ${D}${bindir}
  install -m 0644 ${S}/my_program ${D}${bindir}
}

These variables are defined in the file poky/meta/conf/bitbake.conf with some of the more useful ones listed below

Useful variables

bindir /usr/bin
sbindir /usr/sbin
libdir /usr/lib
sysconfdir /etc
