BASIC_SETUP_FUNDAMENTAL_TOOLS

# Now we can determine OpenJDK build and target platforms. This is required to

PLATFORM_SETUP_OPENJDK_BUILD_AND_TARGET

# Continue setting up basic stuff. Most remaining code require fundamental tools.

BASIC_SETUP_PATHS

BASIC_SETUP_LOGGING

# Check if it's a pure open build or if custom sources are to be used.

BASIC_SETUP_OUTPUT_DIR

# Must be done before we can call HELP_MSG_MISSING_DEPENDENCY.

HELP_SETUP_DEPENDENCY_HELP

# Setup tools that requires more complex handling, or that is not needed by the configure script.

BASIC_SETUP_COMPLEX_TOOLS

# Check if pkg-config is available.

PKG_PROG_PKG_CONFIG

# After basic tools have been setup, we can check build os specific details.

PLATFORM_SETUP_OPENJDK_BUILD_OS_VERSION

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

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