Just "make buildenv" and you get a shell with all the environment variables set up for doing builds (or cross-builds if you set TARGET_ARCH) within that source tree. If csh isn't your favorite shell, set BUILDENV_SHELL in your environment. There's also a "buildenvvars" target that will let you capture the environment you need so that you can use it within your own build scripts without needing an interactive shell. -- Ian
