I just started using LPCExpresso, although I've used Eclipse for years.

I noticed that a build that has to do no compile or link (nothing changed) takes a surprisingly long time (about 12 seconds on a fast Mac Mini/Mountain Lion with SSD). In this case, I am compiling a demo LED flasher for the LPC1769, and had only changed one source file (the tiny demo mainline). Details below...

The 2 Build Console windows each show a start and end time of 1 second, but the start time is 12 seconds into the build.

My questions are:[list]
  [*]What's it doing and how can I find out what it is doing?
  [*]Can it be speeded up


Is there a way to get a detailed output? During the build, it shows a series of steps on a pop-up, but doesn't log them in the console, and they are vague "Invoking Command:" (i.e. no command is shown).


The only projects open in Project Explorer are my test project (MyTwinkle) and CMSISv2p00_LPC17xx

Here is one of the console outputs:

14:27:06 **** Incremental Build of configuration Debug for project MyTwinkle ****
make all
make: Nothing to be done for `all'.

14:27:06 Build Finished (took 80ms)

Here is the other:

14:31:41 **** Incremental Build of configuration Debug for project CMSISv2p00_LPC17xx ****
make all
make: Nothing to be done for `all'.

14:31:41 Build Finished (took 80ms)
