Question about optimizing packages int Makepkg.conf

slughappy1 · 2009-04-01 18:48:24

I edited my Makepkg.conf file so that it knows that I have a Intel Core 2 Duo. Do I need to rebuild any packages? How do I go about it if I do?

Depends on what changes you made. So what changes did you make? And man makepkg.

Ranguvar · 2009-04-01 21:47:42

You can build packages with ABS, check the wiki. Do you need to rebuild any packages? No... but the whole point of modifying that file is to change how packages are built in the first place.. so if you want a package rebuilt with those settings, rebuild it.

adamlau · 2009-04-01 21:59:28

Yup, you need to brush up on ABS and PKGBUILD first.

I haven't made any packages with ABS, I wasn't sure when I setup Arch if anything needed to be rebuilt. I changed Core 2 Duo/Quad/Xeon/Pentium 4 P6xx

CHOST="i686-pc-linux-gnu"
CFLAGS="-march=prescott -O2 -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"
MAKEFLAGS="-j3"

makepkg.conf only comes into play when you build packages. Installing packages from the repos with pacman doesn't call makepkg.conf.

You can use "-march=native" instead of "march=prescott" and GCC will choose the correct processor.

Isn't prescott the right config for an Intel Centrino Core 2 Duo? That's what the guide says. Although, I once tried to install Gentoo. I think I remember that someone told me that prescott is just the current form, and that for the core 2 duo it was going to change. Or something like that

I don't know that chip. I do know that if you use 'native' that GCC will correctly identify your processor.

Did you change CARCH also?

Prescott is for the i686 version, Nocona is for x86_64.

Note that this is, I'm pretty sure, independent of what architecture your OS is running (32-bit vs 64-bit).

Yeah. What I meant was that if you're running i686 on your Core2Duo it's a Prescott. If you're running x86_64, it's a Nocona.

But the wiki says to use core2 not nocona

I do not believe that I had to change the CARCH.
