ctl_api.h - error when compiling

Hi,

I'm experimenting with some ctl functions and have come across a problem:

If I "#include ctl_api.h" in my source compilation breaks of with an error and complains about:

>> ctl_api.h     expected ';',':', or ')' before numeric constant <<

The offending place in ctl_api.h is:

// Set/Clear the leds on the board
void ctl_board_set_leds(unsigned set);

I suspect a missing 'int' after the 'unsigned'.

Now, CrossWorks keeps me from overwriting the original file so I've stopped in my tracks:

Bug or misunderstanding on my side? :)

Thanks,

Christoph

  Let me re-phrase that ;)

  It's very probably a typical beginner's error: I added an include file and expected the compiler to find the functions somehow without adding the source itself. Without the include I got an "implicit definition" warning, with it I got an error because some of the functions from the include file were not added to the project.

  I re-made the project, using a different package for my board/processor combination now which adds some other sources. So now it seems to work :)

   

  Sorry for the noise (which reminds me: a "bloody beginners forum" would be nice ;) )

  Sorry. No work, more noise ;)

  I've now added the complete project for inspection. I gues it's very simple but I don't get it ...

  In the current version, compiling will work but with warnings for the 'implicit declaration of function 'ctl_at91sam7_get_mck_frequency' '.

  When I uncomment line '//#include "ctl_api.h"' in 'main.c' and/or 'delay.c' I get an error:

  ---------------------------------------------------------------------

  Find    delay.c

  Error   ctl_api.h   expected ';', ',' or ')' before numeric constant

  ---------------------------------------------------------------------

  What is it? Please help ...

  typedefs.h contains

  #define set 1

  ctl_api.h has

  void ctl_board_set_leds(unsigned set);
  
  

  Regards
