# 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

# Note about variable and function references: inside all blocks that are

# - 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

# the expected value. This mechanism is for example used for the TARGET_PATCH

# - All other variables should be referenced with a double dollar sign:
# $$(TARGET_DIR), $$($(2)_VERSION), etc. Also all make functions should be
