Hello list,
I just got a new box for use at work, its an Intel Core Duo 1.8, 1GB
RAM, with an Intel graphic card, its a IBM Lenovo machine. My old one
is an Itautec Athlon XP 1.1GHz with 512MB RAM and an Nvidia AGP
graphic card.
My make.conf (intersting part):
CFLAGS="-mno-tls-direct-seg-refs -O2 -pipe -fomit-frame-pointer
-march=athlon-xp"
CHOST="i686-pc-linux-gnu"
CXXFLAGS="${CFLAGS}"
MAKEOPTS="-j2"
I'd look at what optimizations the march athlon-xp uses and compare that
with the march you are going to there maybe some that you want to enable
for the Core Duo. The CHOST shouldn't be an issue. It should be noted
that you won't have an 64bit support if the new CPU even supports this
don't remember off the top of my head. I suspect it will run without
issues though.
What I want to know is, will my software, compiled with the above
settings, run in the new processor?
Cause if it does, I may be able to compile a generic kernel set (using
genkernel) and udev should take care of most module loading, and I
won't need to rebuild all my stuff. I've tested some binary packages
with an old Pentium III processor, and it worked...
Anyway, should I start from scratch or there's an easy way to migrate
all this stuff?
