Re: [Contiki-developers] Contiki under Windows

[<su...@ib...>]

Hi,

I made few modifications to make the contiki code as original as possible...
(now, there are only differences into the clock() function and in the uipopt.h module)
See comments in the post below...

(If you receives this email two times plz forget it - I got problems with my SMTP)

OK, changed

OK, changed

The cclock() function is implemented into the thread_timer() function (which is a thread).
I dont know why the clock() function does not work well with the CYGWIN (bug?)... some times the clock does not get incremented - timer() functions are never called...

OK, placed that code into the contiki thread.

no problem!
just do it :)
