################################################################################ # 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 _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. # ################################################################################ # # Utility function to upgrade config.sub and config.guess files # # argument 1 : directory into which config.guess and config.sub need # to be updated.
