Clock skew detected!!

[abhishekdey1985]

Hi, I compiled Irrlicht on Ubuntu 8.10 - Intrepid Ibex version.

I get the following warning after the compilation:

Code: Select all

make: warning:  Clock skew detected.  Your build may be incomplete.

What i understand from this is that some of the files that are being compiled are newer then the current system time (If i am not wrong).

Will it effect the running and compilation of Irrlicht programs??

Need Suggestions. Thnx in Advance!

Now when i compile my Irrlicht program on Ubuntu it gives this:

Any suggestions!!

means, iirc, that the time on your local machine has changed. make is then a bit hindered somehow and this can apparently lead to faulty results. maybe there's some process running in background which changed your time while building... or you did it by yourself. no idea

Thanx wiTTus!

I found what was the problem. I had a little trouble with my BIOS battery. Replaced the battery, set new time and compiled again. Now its working awesomely fast!! Thanx again!
