[Scons-users] Command vs. Action

[Stefan Seefeld]

Hello,


in my SConscript file I have


  def BoostRun(env, prog, target, command = "./$SOURCE > $TARGET"):
      run = env.Command(target, prog, command)
      return run

which works reasonably well. I'd now like to fine-tune this to print a
custom message rather than the actual command being executed. Apparently
I need to use an 'Action' to do that, so I substitute the above by


  def BoostRun(env, prog, target, command = "./$SOURCE > $TARGET"):
      run = env.Command(target, prog, env.Action(command,
cmdstr="testing..."))
      return run

This however yields an error, as the generated command is (almost)
empty, i.e. $SOURCE and $TARGET are not properly substituted. Can anyone
tell me what I'm missing ?

Thanks,
        Stefan
