################################################################################ # WAF package infrastructure # # This file implements an infrastructure that eases development of package # .mk files for WAF packages. It should be used for all packages that use # WAF as their build system. # # See the Buildroot documentation for details on the usage of this # infrastructure # # In terms of implementation, this WAF 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 WAF behaviour. The package can also define some # post operation hooks. # ################################################################################ ################################################################################ # inner-waf-package -- defines how the configuration, compilation and # installation of a waf package should be done, implements a few hooks # to tune the build process for waf specifities and calls the generic # package infrastructure to generate the necessary make targets # # argument 1 is the lowercase package name # argument 2 is the uppercase package name, including a HOST_ prefix # for host packages # argument 3 is the uppercase package name, without the HOST_ prefix # for host packages # argument 4 is the type (target or host) ################################################################################ define inner-waf-package # We need host-python to run waf $(2)_DEPENDENCIES += host-python $(2)_NEEDS_EXTERNAL_WAF ?= NO # If the package does not have its own waf, use our own. ifeq ($$($(2)_NEEDS_EXTERNAL_WAF),YES) $(2)_DEPENDENCIES += host-waf $(2)_WAF = $$(HOST_DIR)/bin/waf else $(2)_WAF = ./waf endif $(2)_BUILD_OPTS ?= $(2)_INSTALL_STAGING_OPTS ?= $(2)_INSTALL_TARGET_OPTS ?= $(2)_WAF_OPTS ?= # # Configure step.
