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