  • showcommands - showcommands is a modifier target -which causes the build system to show the actual command lines for the build -steps, instead of the brief descriptions. Most people don't like seeing the -actual commands, because they're quite long and hard to read, but if you need -to for debugging purposes, you can add showcommands to the list -of targets you build. For example make showcommands will build -the default android configuration, and make runtime showcommands -will build just the runtime, and targets that it depends on, while displaying -the full command lines. Please note that there are a couple places where the -commands aren't shown here. These are considered bugs, and should be fixed, -but they're often hard to track down.
