Some installation questions

Kodama · Posted: Tue Jan 28, 2003 8:15 pm Post subject: Some installation questions

Hi, I am rather newbie at linux, I have used Mandrake for a month, but I managed to break it after doing some rpm commands with dodeps and force flags, when upgrading glibc. So I wanted to try a distro that don't use rpm's. Maybe Gentoo is too diffcult for me, but I figure I could give it a try. Now I am wondering if you could help me with these questions....

1. For incresed speed, are these flags good? Should I set the march flag to i686 instead? Or should I just skip this and install from stage3?

CHOST="i686-pc-linux-gnu"
CFLAGS="-march=pentium2 -O3 -pipe -fforce-addr -fomit-frame-pointer -funroll-loops -frerun-loop-opt - frerun-cse-after-loop -falign-functions=4"
CXXFLAGS="$CFLAGS"

My CPU: Pentium Celeron(Mendocino) 400 (@450)

2. Can reboot my computer during installation and start Windows, and later resume installation? If I want to search for help. If not, can I use Lynx to search for help?

3. If I want to install Xfree and a WM after (or during?) the installation, do I type this for example?
"emerge xfree4"
"emerge kde"
Or? I am just guessing.

You optimizations look a little strong...

I have a celery 400 too, and I can tell you from experience being that vigorous isn't going to help you much, in fact I've been getting better performance after I lightened up the settings (...because of cache usage... celeries dont' have much cache..)

For your celery you should definatly use -march=pentium2 and not -march=i686.

My CFLAGS are "-O3 -march=pentium2 -fomit-frame-pointer -pipe" and I'd recommend you using the same flags. If you don't want to use mine permenently then I recommend atleast during the install and then change them afterwords.

Yes, you can reboot during certain parts of the install, but if you can avoid it you'll be better off. It's easier to keep on track and do things correctly if you follow it straight through and not reboot.

And be forewarned that you might have problems with a stage1 install due to
your overclocking. Do a forum search on "segfault AND overclock".

I agree that your CFLAGS are too aggressive, especially for your first attempt.

Even with maximum optimization, you'd probably only seen a couple of percent
performance increase, if that much.

If you want to install KDE and xfree, you can just emerge xfree kde, and then you wait.

I would actually recommend using -O2 rather than -O3. There has been several issues where the compiler crashes due to -O3 in some packages.

If you want to emerge KDE and Xfree in one swipe, you can even just do 'emerge kde', since it depends on XFree, it will install it first than KDE

You have to create the directories again.
