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

# As we configure with --prefix=/usr, this fix needs to be applied to

#

# substitute away any occurrences of these directories with @BASE_DIR@,

# Note that STAGING_DIR can be outside BASE_DIR when the user sets

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