Hi,
I am trying to simplify our custom buildroot packages that define the
build rules for our internal software packages. So far these packages
duplicate a lot of akward code in their .mk files. I'd like to move this
to a central place. So what I did is to add code like this to
package/raumfeld/raumfeld.mk:
-------------------------------------------------------------------------
################################################################################
# inner-raumfeld-autotools-package
#
# argument 1 is the lowercase package name
# argument 2 is the uppercase package name
# argument 3 is the package directory prefix
################################################################################
define inner-raumfeld-autotools-package
ifndef $(2)_BRANCH
$(2)_BRANCH = $(call qstrip,$(BR2_PACKAGE_RAUMFELD_BRANCH))
endif
ifndef $(2)_MODULE
$(2)_MODULE = $($(1))
endif
ifndef $(2)_VERSION
$(2)_VERSION = $($(2)_BRANCH)
endif
# Call the generic autotools package infrastructure to generate the necessary
# make targets
$(call inner-autotools-package,$(1),$(2),$(2),$(3),target)
################################################################################
# raumfeld-autotools-package
# -- the target generator macro for Raumfeld autotools packages
################################################################################
raumfeld-autotools-package = $(call inner-raumfeld-autotools-package,$(call pkgname),$(call UPPERCASE,$(call pkgname)),$(call pkgparentdir))
################################################################################
################################################################################
include package/raumfeld/*/*.mk
-------------------------------------------------------------------------
As you can probably guess the idea here is to define PKG_BRANCH, PKG_MODULE
and PKG_VERSION with default values but still leave the possibility to
override these from the respective pkg.mk files.
So what am I doing wrong here, because PKG_VERSION ends up being
"undefined" instead of defaulting to the value of
$BR2_PACKAGE_RAUMFELD_BRANCH ?
Thanks for your help,
Sven
