First, you should try restarting once and trying to compile the program again, as restarting will recreate all files in /dev ...

Else, you can change dates of files in your system using the "touch" command. Running 'touch *' in a directory will set all files in the current directory to have the current system date as their modificaction date.

As you need to change the dates of all files in the system, you will need a simple loop to do it, something like running

Code:

for i in `find` ; do touch $i ; done

In the / directory.

But be careful, running this changes all dates and may have a bad affect on some applications/processes. Also you should unmount all drives before running this.

Ujjwal, why go into a for loop when find itself can execute commands upon its output?

Code:

 $ find . -exec touch {} \;

I wasn't aware of that, thanks for the info

i restarted and recompiled... but stil it says... WARNING: <filename> is upated 1.1e 03 seconds in future... or something... and at the end it says

warning: clock skew detected: your build may be incomplete

can i use that command u gave to reset the dates? wil that be of any real harm? y should i unmount the drives?

Note: True programmers never worry about WARNINGS ... Then only worry if its an ERROR

GCC/Makefile uses source file's timestamp to determine which files need to be recompiled, and which have been edited. I guess Ujjwal's trick might just work!
