# Advance Toolchain main Makefile
#
# This file is where all the build starts.
#
# Common targets:
# all - Default target. Build and package the Advance Toolchain.
# Options:
# DESTDIR - Specify the directory where the AT directory
# will be created, e.g.: DESTDIR=/opt
#
# AT_CONFIGSET - Indicates which config set to use.
# Possible values include the name of directories
# inside configs/, e.g.: AT_CONFIGSET=7.0
#
# BUILD_DEBUG_ON - Forces that all build stages be
# retained. Possible values are "yes" or "no".
# If set to "yes", all temporary build steps are
# retained, regardless of the package setting on
# ATCFG_HOLD_* variables.
#
# BUILD_ARCH - Specify which archicteture this toolchain
# will be targeting. Most config sets have their
# default values, but in same cases the config
# set is able to build toolchains for different
# architectures, e.g.: BUILD_ARCH=ppc64le or
# BUILD_ARCH=ppc64
#
# AT_MAKE_CHECK - Specify if package testing should be
# done during the build. Setting this to a value
# other than 'none' will enable testing for all
# packages that have atcfg_make_check defined in
# their stage file. This can be overridden at
# the package level by setting the value of
# ATSRC_PACKAGE_MAKE_CHECK in a package's
# source file. The values for this variable are:
# - none: do not enable package testing at the
# global level
# - strict_fail: Enable package testing at the
# global level and cause the build to fail if
# a package's testing fails.
# - silent_fail: Enable package testing at the
# global level but do not cause the build to
# fail if the package's testing fails.
#
# BUILD_IGNORE_COMPAT - Tells to ignore runtime-compat
# package building. If not provided, it's inferred
# by the contents of AT_OLD_KERNEL on the specific
# <distro>.mk config file.
#
# BUILD_IGNORE_AT_COMPAT - Tells to ignore atXX-compat
# package building. If not provided, it's inferred
# by the contents of other configset variables.
#
# pack - Create a tarball with all the source code necessary to build AT
# on another server.
#
# clone - Clone a config set, copying or symlinking its files.
# Options:
# FROM - Name of the config set being cloned.
#
# TO - Name of config set being create.
#
#
# test / fvtr - Runs the build and the FVTR test suite to validate it.
# Options:
# TEST_NAME - Name of a particular test suite case to
# run (this limits the test case run to this
# single test).
#
# Make sure we're running a recent enough GNU make version.'

# This is a simple heuristics to find out if we need to build the atXX-compat
# RPM package. It's loose and wide in tending to choose a build instead of a
# build denial (it considers "compat" and "supported" previous AT distros), so
# if you are sure that you must skip this package build, state it clearly on
# the config files (preferably on the distro.mk related file), or the check
# could be further restrained.
# Having said that, there is a quick description of its logic:
# We first collect all the supported and compat distros related to this build,
# and for each of them, (from earliest to oldest) we try to locate base support
# for it on the previous AT version. If base support is found, we try to
# identify if the particular build being done was supported (BE or LE). If it's
# found, we send back a "no" as a GO for the build of atXX-compat, otherwise,
# we send back a "yes" as a NO GO (ignore) for the build of atXX-compat.
# Note that we could restrain it further, looking only for AT previous
# "supported" distros, but I'm not sure that it's the correct path to follow.
