 Posted: Sat Jan 11, 2025 11:58 am Post subject: Is my computer suitable for gentoo? |
 |
|
Hi, I just installed gentoo on a spare old computer. I have been paying attention to gentoo for a long time, and now I have the conditions to install gentoo on a physical machine. But my computer is too old. When I installed the following software, the software package net-libs/webkit-gtk took a long time to compile. It took one night and half a day and it was not compiled yet. This makes me a little confused whether my computer is suitable for installing and using gentoo. Can anyone give me some advice? Thanks a lot.

I tried to install clash-verge-bin. After taking a long time without completing the installation, I tried using the binary package. But I still have to compile net-libs/webkit-gtk.

Anyway, I still think gentoo is a very good operating system.
I want to install clash-verge-bin, is there any other convenient way to choose? |

cien,
That system is suitable for Gentoo, just a little slow.
With only 4G RAM, you may want to restrict MAKEOPTS for big packages, as building on fewer cores will be faster than running out of real RAM and swapping.
Most of the content of make.conf can be set on a per package basis.
Gentoo also splits nicely into what you need to run Gentoo and what you need to build Gentoo.
That means that its possible to make your own binhost the way you like it. I keep an old AMD 350 alive that way.

I tried to do what you said. But something went wrong and I couldn't use xorg. I canceled the binary package and recompiled the world before I could use xorg properly. I still need to compile net-libs/webkit-gtk. But that's okay. I am learning how to use v2raya.

There was someone with a Pentium Sandybridge recently that was getting sigills and looks like this is happening. Make sure your CFLAGS do not use -march=sandybridge -- at least you need to disable AVX if you do.

Thank you for your reply. Hi, I am a new gentoo, I am not very familiar with the features of "use falg", may I ask what I should do now?

In your COMMON_FLAGS you have "-march=native" which is telling gcc what instruction set it should output. I wonder if gcc can figure out you're using a non-avx sandybridge with -march=native else you'll need to explicitly add -fno-avx after -march=native in your make.conf ... but unfortunately you'll need to rebuild any packages that got the illegal instructions - which at minimum is x11-libs/libdrm .

Start by showing us what gcc interprets -march=native to mean on your hardware, and show us the contents of /proc/cpuinfo.
You mentioned using binary packages. Are the broken files ones that you built locally or did you get them from a Gentoo binhost? |

Run this:
| Code: | | $ gcc -march=native -E -v - </dev/null 2>&1|grep cc1 |
This will dump out the command line that it will use to generate assembly code when it compiles.
I expect it to contain -march=sandybridge but I hope it will include -mno-avx among other things the Pentium sandybridge doesn't have that the Core i3 and higher sandybridge do ...
In any case, explicitly shutting off avx instructions for your Pentium is a good thing, and if you eventually do things like distcc it will help things if you don't use march=native ...

Please consider setting PORTAGE_TMPDIR to hard disk at package level definition:
wiki
Local example here | Code: | sed -e '/tmpfs-no/!d' -e '/gcc/!d' /etc/portage/package.env/*
sys-devel/gcc tmpfs-no.conf |
| Code: | cat /etc/portage/env/tmpfs-no.conf
PORTAGE_TMPDIR="/var/no-tmpfs" |
sys-devel/gcc should be targeted if build from source.

| Although OP is a bit low on memory to build large packages in tmpfs, at this time we have no reason to believe OP is using a tmpfs for any package, large or small. If /var/tmp/portage is on physically backed storage, there is no need for a per-package override. |

Let's restate my Luddite pov.
It should be convenient & compact to default PORTAGE_TMPDIR to tmpfs.
Such targeted packages would build faster.
However memory hungry package builds should be redirected to HD as described initially.
Such targeted packages could allow higher MAKEOPTS.

CaptainBlood,
What you say is factually correct but does not help fix the immediate issue, which is Illegal Instruction exceptions.
The OP should save your advice for later, once their install works properly.
Making it work is the priority now.
Making it leaner, meaner, faster, whatever can come later.

Okay yes based on some anecdotal evidence from here and on stackexchange, -march=native for gcc on a Celeron or Pentium Sandybridge will produce incorrect results. -march=native will work properly only on Sandybridge CPUs that are i3-2xxx, i5-2xxx, i7-2xxx, and their Xeon counterparts.
So I think that COMMON_FLAGS in /etc/make.conf will need to be changed to something like:
COMMON_FLAGS="-O2 -pipe -march=sandybridge -mno-avx -mno-aes"
and you'll need to
# emerge --oneshot x11-libs/libdrm
This hopefully will fix your X11. Then the other problem is there may be other packages that have this issue. You may be forced to
# emerge --emptytree @world
but don't do this yet unless you have absolutely no way to find which packages were compiled wrong. It may be faster to start over from a fresh stage3 if you haven't invested much time.

It should be possible to identify bad packages by finding those which have -march=native recorded in their CFLAGS in the vdb. The user would still need to identify which packages actually used those CFLAGS[1], but it would be a smaller set than emptytree.
[1] Packages that only install text files, like documentation or Python scripts, will have recorded their CFLAGS, but never used them, and so do not need to be rebuilt. |

So I think that COMMON_FLAGS in /etc/make.conf will need to be changed to something like:
COMMON_FLAGS="-O2 -pipe -march=sandybridge -mno-avx -mno-aes" |
Wonder if such a issue has been reported upstream?
IIRC I've seen some gentoo dev reporting bugs for sys-devel/gcc...
Maybe there's something I'm missing...
Thks 4 ur attention, interest & support.

Don't know. I've never had one of these cpus to independently verify that this is true, but there's not just one person that have tried march=native and march=sandybridge with no other flags that end up with unusable avx instructions. I suspect that there are other low end cpus that have this issue.

This will dump out the command line that it will use to generate assembly code when it compiles.
I expect it to contain -march=sandybridge but I hope it will include -mno-avx among other things the Pentium sandybridge doesn't have that the Core i3 and higher sandybridge do ...
In any case, explicitly shutting off avx instructions for your Pentium is a good thing, and if you eventually do things like distcc it will help things if you don't use march=native ... |
Hi, eccerr0r.Thank you.
Sorry for the late reply. I did what you said.

Thank you all for your response. I really appreciate it.
The following error occurred when I ran the following command. Is it caused by the same problem?

Hmm!
Looks like march=native is doing the right thing for your cpu...
But!
Now the binhost is suspect. It seems that it wants march=x86-64-v3 ... now as far as I can tell, this is not acceptable, x86-64-v3 IIRC includes AVX (and AVX2) instructions and AES as well. Perhaps you can use the base x86-64 directory instead? But now it looks you have some v3 binpkgs installed and these will need to be removed.
Are there other things that require x86-64-v3 now? Was the stage3 compiled with it?
Ugh. I need to upgrade my computers too, I don't think I have any machines that even support v3...
