What happen if not use FILE in a recipe?

In yocto recipe, we can use FILE to assign which file or directory will be existed (this is my understanding).

What would happen if don’t assign value to FILE?

Ex:

FILES_${PN} += "/usr/local/bin/foo.sh"

do_install_append () {
  install -m 755 -d ${D}/usr/local/bin
  install -m 555 ${S}/foo.sh ${D}/usr/local/bin/
}
Solution

  • FILES_<packagename> variables define what files will be included in the package (${PN} refers to the recipes main package). The variables have default values (see meta/conf/bitbake.conf). These default values can be changed by your recipe or a class it inherits. You can check the final values with bitbake -e <recipe>|grep ^FILES_.

    If your recipe installs files that are not included in the final FILES_* values, bitbake will complain.
