Segmentation (My Computers) Fault

Bague · Apprentice Joined: 09 Feb 2004 Posts: 292

Well, I have been working for over a week now trying to get an old machine to work as a web/audio server. SO far, I have hit many brickwalls, and this current one seems like the last, but it is a deadly one.

Everytime I try to emerge certain key parts of the system such as GCC, my computer segfaults. I tried curing this by doing a stage2 install, but then something in "system" gave me a segfault. I'd rather not be dependant on packages, and even so, this worries me.

I have ran memtest86 for 13+ hours with no errors, does anyone have an idea what may be going on here and how I can cure it?

That's way too little information about your problem. What are the specifcations of your machine, what exact steps did you take until the problem occured. What exactly is your error message and what is your configuraiton, most important the one in "/etc/make.conf". Unless you provide us with more informaiton we won't be able to help out.

PC Specs:

AMD K6(-2?) 300 Mhz
128 MB RAM
Crappy POS Video Card (does not matter, is not needed)
D-Link Network Card
Ensoniq SOund Card (old)

I went through with the regular stage 1 installation, and then when doing bootstrap, GCC gave me a segfault telling me to submit to bugs.gentoo.org.

Later I went through stage2, the make.conf configs were Use="-gtk -qt -kde -gnome -X alsa" the Chost and CXXFLags were auto on stage2 and mcpu="i586" on stage1.

It seems that not all things are segfaulting, just certain ones.

I don't see anything wrong with your settings @ first glance.

What I can provide is a config from an existing gentoo installation on a AMD K6-II machine.
Relevant part's of "/etc/make.conf":

Ok, my processor is a K6 original. I am wondering what all USE flags I should use, since this is going to be a simple web/audio (play music through my speakers constantly) server. I don't want X or anything graphical since I am going to be handling the access via SSH. All I plan to use on the server is: Apache, php, mysql, cplay (or another audio player), alsa, ssh(d). Any large suggestions for use flag? I don't want to compile unnecessary things on a K6

EDIT: Hmmm, another thing, when tarring the stage file, it says Error, Error delayed for previous reasons (or something like that, this is in links2 on the livecd so I can't read it at the moment.

What does "tar: error exit delayed from previous errors" mean? I have gotten this both with a stage from the cd and one from online.

From the page I am reading, it seems that my processor is indeed a K6-2. Its model number is 8 with a stepping of 0, 64 MB cache, 300 Mhz CPU Family 5.

Aha, yeah, that was a typo. In these days I seem to forget the existence of Kilobytes. I am sure 7 years from now We won't know what the hell a megabyte is anymore and will be working with Gigabytes and Terabytes in much more mass.

Good thing that tar error wasn't important, that was scaring me. RIght now I am doing mirrorselect (the old version of the guide had some bad info which began to load /make.conf with a bunch of useless code (it didnt have grep GENTOO_MIRRORS= in it). Luckily I handled that. SO far so good.

It is nice to know what hardware this thing as, since previousely I was completely unaware (it was a hell of a lot easier with my own machine because I built it myself, this server was actually a dekstop computer built by my brother 7 years ago.

EDIT: Emerge sync-ing now

After using mirrorselect just make sure your "/etc/make.conf" is still usable.

Shoot, got this during the bootstrap,

Now I'm starting to run out of ideas.

During compilation of the first two states the cpu is used quite heavily ensure that the necessary cooling is provided. (Last week we had a machine with random crashes nothing to do about it every test we made passed until we started testing over night; long story short conclusion; cpu fan died and if cpu use was too high cpu overheated and crashed)

I don't know if this can help you further, give it a try.

Keep the list posted and hope up.

Hmmm, do you think I could use DistCC and do all the compilation on my AMDXP 1600+ computer?

inode77 · Posted: Wed Sep 08, 2004 7:49 pm Post subject:

I have no expirience with distcc, but AFAIK that would be no problem, so I suggest you give it a try and post back what you expirienced.

This time (with distcc I believe, I may have to check it though), it just plain froze.

Sorry to here it! I then suggest the following take a x86 stage3 (not a i686 just the plain i386 one) and go from there then edit the use, cflags and host settings to your likings and do a emerge -e world once you have your sys up and running.

Hmm, I "finished" the stage three install, setup the gs-sources kernel, booted it up, selected it in GRUB, and watched my computer reboot itself with no prompts.

I am trying to compile a different kernel (vanilla-sources), but I never recalled actually installing the prebuilt packages (I am bouncing off of two versions of the handbook which makes this confusing). I thought it might be the GRP, but that appears to require a nonexistent second CD, and also is done AFTER boot.

So basically I am asking, where and how do I install the prebuilt packages with stage3? Or is that already done when you untar the stage?

The second cdrom has precompiled packages on it and is just available via bittorent or if you buy it from an offical reseller.

As for your choice of kernel I strongly suggest to go with the gentoo-dev-sources 2.6.8.1. It's actual, has some good pachtes and it's better than 2.4.

After installing stage3 you only need syslog-ng, vixie-cron and special fschk progs from the precompiles section of the cdrom. Their for sure on cdrom1. Then change your config type env-update && source /etc/profile followed by emerge -e world to recompile with the optimized kernel. (i586 as base host definition brings a lot concerning performance that is wasted with i386)

Hmmm, do you have any links for the second CD on bittorrent?

Also, even after compiling the vanilla kernel, (I will try dev later), it still does not boot. It simply says the GRUB info and then restarts. WHy would this happen? Any ideas for a cause and cure?

Or any mirror should do.

And a thing I didn't know either, there are iso available for the package cd but just x86.
