Errors in kernel compile

eulipion2 · Posted: Tue Jul 04, 2006 4:08 am Post subject: Errors in kernel compile

Hello,
This is my first time (second, if you count earlier today) trying to install Gentoo, or any other Un*x for that matter. I am running an old iMac G3 that I recently used my OS X install cd to format into a Unix architecture, then started with the user guide from step one, following religiously, except where necessary for my platform. Following the user installation guide I keep getting a series of errors when I make it to step 7d. Using Genkernel. I chose the genkernel route as this is my first time and I wanted to make sure it'd work. But it doesn't. Here's what I did, starting from step six:

6. Choosing the right profile:
#ls -FGg /etc/make.profile
/etc/make.profile -> ../usr/portage/profiles/default-linux/ppc/ppc32/2006.0/G3/

Configuring the USE variable:
# nano -w /etc/make.conf
CFLAGS="-O2 -mpcu=750 -fno-strict-aliasing -pipe"
CHOST="powerpc-unknown-linux-gnu"
CXXFLAGS="${CFLAGS}"
MAKEOPTS="-j2"
USE="gtk gnome kde qt dvd aac alsa aim apache apache2 bash-completion bluetooth clamav cups dvd ftp"
**NOTE: did NOT alter USE variable first time, same results**

7a. Timezone:
# cp /usr/share/zoneinfo/EST5EDT /etc/localtime

7b. Installing the sources:
# USE="-doc symlink" emerge gentoo-sources
# ls -l /usr/src/linux
/usr/src/linux -> linux-2.6.16-gentoo-r9

7e. Alternate: Using genkernel:
# emerge genkernel
# zcat /proc/config.gz > /usr/share/genkernel/ppc/kernel-config-2.6
# genkernel --genzimage all

I'll print out the errors from /var/log/genkernel.log in my next post.

Can anybody make something of this? Will I need to start from scratch again? (I know I shouldn't have, but I really had to turn off the system for the night. Lack of wireless range forced me to put the box in an inconvenient place to get a good signal.)

Thanks in advance!!!

That does look awkward.
Firstly have you looked to see if the .h file is actaually there?
I just looked at it; it has 3 lines and all are commented out.
Can try re-emeging the genkernel; it might have just missed it.
One other possible source; if you mounted the new gentoo system from live-cd,
did you execute

Genkernel doesn't really work with 2.6.16, the ppc architecture changed some important settings (ARCH changed from ppc to powerpc). If you really want to use Genkernel, it's best to use 2.6.15. I would recommend using make pmac32_defconfig instead to create a default config which should boot on your machine, then tweaking it to remove the stuff you don't need. It's easier than it sounds. :)

Thanks to everybody so far!

JoseJX,
How would I go about doing what you said? I'm very new to the technical aspect of Unix/Linux, having only tinkered with it via Terminal in Mac OS X (did manage to upgrade VIM, Apache2, PHP, and MySQL, but that's it)

As for the prospect of a hardware problem, I've been able to install both Mac OS 10.4 and I'm at 84% on my Yellow Dog install, which I'd keep, but you can't really learn anything if the computer does it for you, so I'd much rather do Gentoo for the learning experience.

Thanks!

The manual configuration section of the handbook explains this procedure: http://www.gentoo.org/doc/en/handbook/handbook-ppc.xml?part=1&chap=7#manual

Feel free to ask if you have any questions.

Okay, here's a quick question, as the documentation doesn't really say. When it comes to assigning filesystems, do I need to assign them to my bootstrap and swap partitions, or just my root?

So far today I've tried installing Yellow Dog and Xubuntu, both of which failed, YDL making it to the last step (I think) before dying with "Framebuffer ioctl failed". I can get OS X up and running perfectly, albeit a little slow due to the age of my machine. However, since I have a new-ish PowerBook with OS 10.4 as my main computer, and I really want to learn about Linux, I find it pointless to not have some fun. Why won't anyting work? AHHHHHHH!

</freak-out>

Thanks!

I assume you're talking about the fstab. As it says in the handbook:

eulipion2 · Posted: Thu Jul 06, 2006 4:16 am Post subject:

So in the docs it says that I can't delete the apple_partition_map, then it says to press "b" to make an "Apple_Bootstrap" partition, then "c" to make a swap and a root partition. Are you saying I can skip the bootstrap partition, or are you saying I don't need to "mkfs.ext3 /dev/hda2"?

JoseJX · Retired Dev Joined: 28 Apr 2002 Posts: 2774

Okay, sorry you weren't clear earlier and I thought you were talking about a later section in the handbook.

You *do* need to follow the handbook here. You can't delete the partition map, it contains the partition information, so deleting it is like erasing the drive. You *do* need to create the bootstrap partition. It will contain yaboot on an HFS filesystem so your computer can boot off of it. You do *not* need to do anything to the bootstrap partition, it's taken care of later by mkofboot.

One more quick question. I think I'm going to try a download install instead of from CD. For an old iMac G3 would I need the stage 3 PPC tarball or the G3 one? Then I'll try using manual configure instead of genkernel and try again. If I follow the manual exactly, assuming I've downloaded the correct stage3 tarball, should it really be that much trouble? I hope this works, and thanks for the help!

Thanks!

JoseJX · Retired Dev Joined: 28 Apr 2002 Posts: 2774

Both will work, but since you have a G3 processor, you want the G3 version. Note that G3 != G4, the G4 builds have altivec enabled which isn't supported on the G3.

How about the march flag in step 5e? I'm not entirely sure what to put for that. And I thought I read somewhere that PPC didn't support the march flag. Suggestions?

JoseJX · Retired Dev Joined: 28 Apr 2002 Posts: 2774

As it says in the handbook, (this is a "common" section for all arches) see /etc/make.conf.example for detailed suggestions for your architecture.

Okay, I've made it to part 10: Bootloader. I made it to

eulipion2 · Posted: Thu Jul 06, 2006 10:39 pm Post subject:

Contents of my /mnt/gentoo/boot directory include 2.6.16-gentoo-r9, but when I point yabootconfig to it it says no such file or directory. Why won't it recognize my kernel?

JoseJX · Retired Dev Joined: 28 Apr 2002 Posts: 2774

Alright, it looks like yabootconfig needs some fixing. :p Try this patch: http://dev.gentoo.org/~josejx/yaboot-kernel.patch like this:

eulipion2 · Posted: Fri Jul 07, 2006 5:36 am Post subject:

JoseJX,
Thanks for the patch. I'm about to use it, but quick question. Back on step 9e, if I chose ext3 as my filesystem, do I need to unpack anything? This Debian article says that ext3 has a tool set called e2fsprogs. Do I need to unpack it? Is it included on the install disc? Once I make it past this, it's on to the patch and hopefully everything will work.

Thanks

JoseJX · Retired Dev Joined: 28 Apr 2002 Posts: 2774

Nope, it's part of the base system, so it's already installed.

Okay, here's a problem. Starting with step 10:

No, I was just expecting you to do it all outside of the chroot. :) Just type exit, and then follow the directions.
