warning: Clock skew detected.

[David St-Onge]

Hi all! I'm somehow new to rtai and I just installed rtai-3.1-test2. My
computer is a intel P4, dual boot XP and gentoo dist. I patched, configure,
make and install all without error a 2.6.4 kernel. Here's my problem:
When I try to make rtai, appear some errors about the clock:

make[3]:Warning: File `GNUmakefile' has modification time 2.4e+06 s in the
future
make: warning: Clock skew detected. Your build may be incomplete.

and the modules dir contain only .ko files (any .o). I tried to set the clock
with date and remake, but the same thing appens. I also found that each time I
reboot, the clock apear to change and I always have to put it back to the rel
time.

Thanks to help

This has nothing to do with RTAI, but :

make clean

make clean

..and set your clock again and then "make"

We had that problem in the company too (compiling something different) and
make clean, set the clock and "make" worked.

Best regards,
Hannes.

Hi,

it sounds as if you have a problem with your bios battery? you say each time
you reboot your system clock changes? does it say 00:00:00 1st january 1970
<-- i think thats the time, as I had a similar problem when compiling on
some 'batterey-less' hardware, it was just a case of fixing the clock in the
bios before i booted into the system.

kind regards

Stephen

Are you using a NFS file server for your source files?
If so you perhaps have different times on your local workstation and on the
server. You should synchronize them (for instance by xntp).
