building a kernel from a mounted partition

[Andy Johnson]

Hi,
It seems to me that you are right. It seems that there is no problem
with the timezone.
I checked and indeed the gcc is slightly different in version
is there a work around here ?
I mean, I have gcc of ubuntu, and gcc of fedora in /mnt/sda3.

Can I somehow tell Ubuntu to use the Fedora gcc instead of its own gcc?


Regards,
Andy
