BASIC_SETUP_PATHS

BASIC_SETUP_LOGGING

# Must be done before we can call HELP_MSG_MISSING_DEPENDENCY.

HELP_SETUP_DEPENDENCY_HELP

# Setup simple tools, that do not need have cross compilation support.

# Without these, we can't properly run the rest of the configure script.

BASIC_SETUP_TOOLS

# Setup builddeps, for automatic downloading of tools we need.

# This is needed before we can call BDEPS_CHECK_MODULE, which is done in

# boot-jdk setup, but we need to have basic tools setup first.

TOOLCHAIN_SETUP_SYSROOT_AND_OUT_OPTIONS

TOOLCHAIN_SETUP_VISUAL_STUDIO_ENV

TOOLCHAIN_SETUP_PATHS

# FIXME: Currently we must test this after paths but before flags. Fix!

# At the end, call the closed hook. (Dummy macro if no closed sources available)
