How to invoke external make when building a node.js module with Grunt

grunt-make

  // use node 'child_process' to exec make
  var exec = require('child_process').exec;

  // register a custom task
  grunt.registerTask('make','invoke external make',function() {
    // set grunt task to async mode
    var done = this.async();

    // execute make (or any other external executable for that matter)
    exec('make',function(error,stdout,stderr) {
      // if the external task returns anything but 0,
      // the error argument will be not null
      if (error !== null) {
        grunt.log.error(error);
      }
      else {
        // 'stdout' is buffered output from the external task
        grunt.log.writeln(stdout);
      }
      done();
    });
  });
