need help with /etc/make.conf

[leo_t]

what i should write in make.conf? i don't know what to write in CFLAG and all the rest, and which flags is recomended to write in USE?

my system is AMD Durun 1800 and i plan to use GCC 3.4.2 and reiser 4 (if i can fix the GRUB issue whick i posted in another topic here)

thanks

if u did a stage 3 tar then i wouldnt recommend messing with it until much later (after ur install as done and ur deciding which desktop to use and etc....)

The CFLAGS you probably want set to something like:

[donjuan]

For stuff besides the USE flags and CFLAGS you should probably take a look at /etc/make.conf.example. The Gentoo developers really do a good job with commenting in example files.

Also, I just found that you need to use athlon for -march and -mcpu. So the difference between -march=athon and -mcpu=athlon is that -mcpu will try to optimize binaries for your CPU without breaking compatibility with older CPUs. Those binaries will even work on a 386, so I'm told. -march=athon will optimize the binaries further, but will break compatibility with non-athlon processors. So they will work on your computer and and Athlon-XP, but don't expect them to run on a P3.

As far as the -O option, you can use -O2, -O3 just optimizes a bit more and will make your binaries a bit larger. Hence using -O3 will also make stuff take longer to compile.

It's probably a good idea to use only needed USE flags. If you use extras they will make your binaries larger and take longer to compile. You can find a list of common USE flags at http://www.gentoo.org/dyn/use-index.xml or in /usr/portage/profiles/use.desc. That isn't an exhaustive list because many are program-specific, like the "f77" (build with Fortran 77 support) and "gcj" (build with gcj, which will compile java to native code) flags only apply to GCC, so they aren't listed. To see the flags that apply to a program you are about to emerge, type "emerge -pv <program>" and that will list the program, its dependences, and all their respective USE flags. + means the flag is enabled, - means disabled.

my advice would be to keep things simple. you're going to be building the foundations of your system, and if something is shaky, it'll come crashing down until later when it really matters. i use the following:

If your duron is 1GHz or over, it is probably a morgan core (based on athlon-xp, supports sse). To check for sure, cat /proc/cpuinfo and see if sse is listed under flags. If so, you have a morgan core, and good cflags would be something like:
-march=athlon-xp -O2 -fomit-frame-pointer -pipe

thanks finally i have an make.conf.
by the way, what exacly in NPTL? i searched the forum but didn't find an answer.

thanks, i finished to install gentoo, rebooted and got a kernel panic.
here is the error:

[donjuan]

Did you build devfs into the kernel or emerge udev?

[leo_t]

i have build devfs to the kernel (built all what needed as said in the gentoo handbook)

[golloza]

Did you enable 'Automatically mount on boot' (CONFIG_DEVFS_MOUNT)?

[leo_t]

[leo_t]

i will try to replace love-sourrces kernel in gentoo-dev-sources
and also, i get an block in portage:

[YD]

linux-headers kernel 2.4
linux26-headers kernel 2.6

So a conflict.

[leo_t]

[leo_t]

well just notised that from some reason gentoo-dev-sources-2.6.9 doesn't support reiser 4, so what kernel should i use?

[nixnut]

You could try mm-sources or nitro-sources (amongst others)
