   2 # Generic package infrastructure
   3 #
   4 # This file implements an infrastructure that eases development of
   5 # package .mk files. It should be used for packages that do not rely
   6 # on a well-known build system for which Buildroot has a dedicated
   7 # infrastructure (so far, Buildroot has special support for
   8 # autotools-based and CMake-based packages).
   9 #
  10 # See the Buildroot documentation for details on the usage of this
  11 # infrastructure
  12 #
  13 # In terms of implementation, this generic infrastructure requires the
  14 # .mk file to specify:
  15 #
  16 #   1. Metadata information about the package: name, version,
  17 #      download URL, etc.
  18 #
  19 #   2. Description of the commands to be executed to configure, build
  20 #      and install the package

 367 # Note about variable and function references: inside all blocks that are
 368 # evaluated with $(eval), which includes all 'inner-xxx-package' blocks,
 369 # specific rules apply with respect to variable and function references.
 370 # - Numbered variables (parameters to the block) can be referenced with a single
 371 #   dollar sign: $(1), $(2), $(3), etc.
 372 # - pkgdir and pkgname should be referenced with a single dollar sign too. These
 373 #   functions rely on 'the most recently parsed makefile' which is supposed to
 374 #   be the package .mk file. If we defer the evaluation of these functions using
 375 #   double dollar signs, then they may be evaluated too late, when other
 376 #   makefiles have already been parsed. One specific case is when $$(pkgdir) is
 377 #   assigned to a variable using deferred evaluation with '=' and this variable
 378 #   is used in a target rule outside the eval'ed inner block. In this case, the
 379 #   pkgdir will be that of the last makefile parsed by buildroot, which is not
 380 #   the expected value. This mechanism is for example used for the TARGET_PATCH
 381 #   rule.
 382 # - All other variables should be referenced with a double dollar sign:
 383 #   $$(TARGET_DIR), $$($(2)_VERSION), etc. Also all make functions should be
 384 #   referenced with a double dollar sign: $$(subst), $$(call), $$(filter-out),
 385 #   etc. This rule ensures that these variables and functions are only expanded
 386 #   during the $(eval) step, and not earlier. Otherwise, unintuitive and
 387 #   undesired behavior occurs with respect to these variables and functions.
