- # Autotools package infrastructure
- #
- # This file implements an infrastructure that eases development of
- # package .mk files for autotools packages. It should be used for all
- # packages that use the autotools as their build system.
- #
- # See the Buildroot documentation for details on the usage of this
- # infrastructure
- #
- # In terms of implementation, this autotools infrastructure requires
- # the .mk file to only specify metadata information about the
- # package: name, version, download URL, etc.
- #
- # We still allow the package .mk file to override what the different
- # steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
- # already defined, it is used as the list of commands to perform to
- # build the package, instead of the default autotools behaviour. The
- # package can also define some post operation hooks.
