[gentoo-alt] problem installing gentoo prefix on debian buster

[Michael Fothergill]

Dear All,

I tried to install gentoo prefix an amd64 box running debian buster.

I am using gcc 8.

It failed as follows:

mv wctype.h-t wctype.h

in #gentoo-prefix on irc.gentoo.org, gentoo-alt@lists.gentoo.org mailing list,
or file a bug at bugs.gentoo.org under Gentoo/Alt, Prefix Support.
Sorry that I have failed you master.  I shall now return to my humble cave.
You can find a log of what happened in /home/mikef/gentoo/stage1.log

I filed a bug report on gentoo bugzilla Bug 687286 and posted the problem here:

Hi,

Can you confirm you don't have xz tool available on your system?

Thanks,
Fabian

Many thanks for the response.  I am not sure if xz utils is installed
by default in debian:

https://packages.debian.org/sid/xz-utils

I will log in to the debian install and check.

Regards and thanks

Michael,

Just to elaborate a bit.  There is a newer version of m4, that is
attempted first.  However, newer versions of GNU software now require
the xz decompressor to unpack.  In your scenario, an old version of m4
is being compiled.  One of the reasons for choosing an older version is
because of not being able to unpack the newer versions due to lack of
xz.  Odd though, as the latest m4 (1.4.18) is also available as .gz and
bz2.

We'd need a larger part of the stage1 log to see why the newer versions
didn't work.

Fabian

Many thanks again.

I checked and xz-utils is installed:

root@fart:/home/mikef# dpkg -s xz-utils | grep Status
Status: install ok installed
root@fart:/home/mikef#

I have pasted more of the output:

https://paste.debian.net/1085996/

I will make a second paste of the start of the output the terminal
buffer didn't catch and post it up as well shortly.

Re: [gentoo-alt] problem installing gentoo prefix on debian buster

[Michael Fothergill]

Many thanks again.

I have posted the output at start of the install run which mentions
this m4 item:

https://paste.debian.net/1085998/

If there is still a bit of output missing that you need please let me know.

There does not seem to be a deb package for wgetpaste.

Re: [gentoo-alt] problem installing gentoo prefix on debian buster

[Michael Fothergill]

I found this discussion:

https://askubuntu.com/questions/1099392/compilation-of-m4-1-4-10-to-1-4-18-fails-due-to-please-port-gnulib-freadahead-c

It suggests the following stepwise solution:

if you want to build m4 from source then start by getting its build
dependencies from the repository:

enable Source code in the Software & Updates (software-properties-gtk)

install needed build tools

sudo apt-get install build-essential

get necessary build dependencies for current m4 binary package

sudo apt-get build-dep m4

get source code of the current m4 binary package (with all needed
patches provided by Debian and/or Ubuntu):

apt-get source m4
cd m4-*

Would a local compilation of m4 this fashion on my debian install help here?

Regards

NF
then compile it as usual

Re: [gentoo-alt] problem installing gentoo prefix on debian buster

I have a separate gentoo installation on this machine.

Could I compile m4 on it and port it to the debian install and run it
there in some way?

Hi Michael,

What does ``m4 --version'' return on your debian install?
I'm no dev, however, if you have a valid m4 install, you shouldn't need to
have m4 bootstrapped.

If m4 is not installed, you may want to do so (as well as bison, patch,
...).

Otherwise, you could apply some patch to m4 during the bootstrap process.
For instance, this bug has been fixed in Gentoo with this patch
https://gitweb.gentoo.org/repo/gentoo.git/plain/sys-devel/m4/files/m4-1.4.18-glibc228.patch

Best,

I agree, install m4 in your Debian box, and it should skip it:

    [[ $(m4 --version 2>&1) == *GNU*1.4.1?* ]] || (bootstrap_m4) || return 1

Re: [gentoo-alt] problem installing gentoo prefix on debian buster

[Michael Fothergill]

The installation seems to be running normally.

A large number of packages have been installed including portage which
seems to be compiling gcc 9......

Regards

MF

Re: [gentoo-alt] problem installing gentoo prefix on debian buster

[Michael Fothergill]

I have posted the output right after the last piece.....

It is seems to be installing an older version of m4 as you suggested
because it could not use the newer one because of a problem with a gnu
package of some sort:

https://paste.debian.net/1085999/

Comments appreciated.

Dear All,

The installation is getting near completion.  Unfortunately portage
seems to be compiling gcc 9.1.0-r1 a second time for good
measure......

This is expected behaviour.  After all packages are brought in, it
finishes with an emerge -e world to ensure everything is "clean", that
is, not pointing to, or using programs or libraries from outside the
prefix.

Dear All,

The installation has succeeded.

I did it in an attempt to try to solve the problems I was having here:

https://forums.gentoo.org/viewtopic-t-1096872.html

Is there some documentation I can read on gentoo prefix?

Re: [gentoo-alt] problem installing gentoo prefix on debian buster

[Michael Fothergill]

Dear Folks,

Is this warning  a big concern?

WARNING: your shell initialisation (.cshrc, .bashrc, .profile)
*          seems to prepend to your PATH, this might kill your
*          Prefix:
*          /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:
*          You better fix this, YOU HAVE BEEN WARNED!

I ran the etc-update on the hosts file.

The system is up to date.  No packages needed to be removed by emerge
--depclean.

startprefix runs OK.

Can I compile a new kernel for the parent debian install in gentoo
prefix and use debian to do the make deb-pkg or make bindeb-pkg or
fakeroot commands if they don't work in gentoo prefix?

Cheers

MF

I think this is pretty much challenging.  IIRC you mentioned something
before, but out of curiosity why would you want a Gentoo kernel for your
Debian system?

Re: [gentoo-alt] problem installing gentoo prefix on debian buster

[Michael Fothergill]

Many thanks for your reply.

The reason for compiling a kernel in gentoo tailored for use in debian
is as follows.

A while ago when the first set of kernels were made with the patches
for the meltdown and spectre vulnerabilities, I
installed the latest kernels with these fixes as soon as they were
released into my gentoo install.

Then I thought to do the same thing in debian.

But there was a problem.

Debian only put out new kernels from time to time and no spectre
enabled off the shelf kernel was available.

So that meant I would have to compile a custom kernel in debian as I
did in gentoo which would have the spectre fix in it.

This turned out not to be an easy task.

At the time you could only compile the spectre fix with gcc 8 and you
could only install it if you were running debian unstable (sid).

I ended up upgrading my debian stretch install to unstable and
installed gcc 8 with some effort.

I tried to configure and install a new kernel using the make kpkg
command in debian but I could not make it work.

It seemed to me that building kernels in gentoo was a lot easier than
in debian at the time.

Since then off the shelf kernels have been created in debian that
contain the meltdown and spectre fixes but I notice there seem to be
new vulnerability fixes
in the pipeline in upcoming kernel releases.

So I then began to wonder if I could make an extra kernel that would
be made to be used in debian at the same time as I would make the
gentoo one - both
kernels being made in gentoo.  The debian one would be ported to my
debian install.

I then posted this on to the gentoo kernel page on the forum site and
Neddy Seagoon the site administrator and Hu the moderator both helped
with some creative
suggestions see here:

https://forums.gentoo.org/viewtopic-t-1096872.html

Neddy Seagoon suggested (at least) two useful things:

1. make a new copy of the makefile for the current kernel and change
the EXTRAVERSION parameter from -gentoo to -debian:
 e.g.
# SPDX-License-Identifier: GPL-2.0
VERSION = 5
PATCHLEVEL = 1
SUBLEVEL = 1
EXTRAVERSION = -gentoo
NAME = Shy Crocodile

He then pointed out that the kernel make system has some useful targets in it:
...
Kernel packaging:
  rpm-pkg             - Build both source and binary RPM kernel packages
  binrpm-pkg          - Build only the binary kernel RPM package
  deb-pkg             - Build both source and binary deb kernel packages
  bindeb-pkg          - Build only the binary kernel deb package
...

2. He then said I would have to copy the kernel directory contents and
compile the new kernel in it etc.

We then had a discussion about the fact that copying the kernel
directory was kind of untidy etc.

Then Hu made a post saying there there were ways to build multiple
kernels from a single tree by setting certain environment variables
($KBUILD_OUTPUT, $INSTALL_PATH, $INSTALL_MOD_PATH) that would mean you
could avoid copying the kernel.

I found a script Hu had posted on this elsewhere on the gentoo forums:

#!/bin/bash

TDIR="$1"; shift
if [ -z "${TDIR}" ]; then
   TDIR="$(uname -r)"
   echo 'No release specified.  Defaulting to '"\"$TDIR\""'.'
fi

TKERN="${TDIR/*_}"
BDIR="$HOME"/kernel/
KSRC="${1:-/usr/src/linux-"${TKERN}"}"; shift

export KBUILD_OUTPUT="${BDIR}${TDIR}/"
export INSTALL_PATH="${BDIR}install/${TDIR}/boot/"
export INSTALL_MOD_PATH="${BDIR}install/${TDIR}/"

if [ ! -d "$KSRC" ]; then
   echo 'Directory '"$KSRC"' does not exist.' >&2
   exit 1
fi

for a in "$KBUILD_OUTPUT" "$INSTALL_PATH"; do
   if [ ! -d "$a" ]; then
      mkdir -p "$a" || exit $?
      echo "Created $a"
   fi
done

echo KBUILD_OUTPUT="${KBUILD_OUTPUT}"
echo INSTALL_PATH="${INSTALL_PATH}"
echo INSTALL_MOD_PATH="${INSTALL_MOD_PATH}"

cd "$KSRC"
exec /bin/bash

I had a go at running it.

If you look toward the end of the gentoo forums thread you will see
the problems i encountered trying to do this in practice.

I had problems making the make deb-pkg and/or make bindeb-pkg command
work in gentoo.

Then I had the idea of installing gentoo prefix in debian itself and
experimenting with the idea of getting the host debian install
to make the deb packages that produce the debian kernel image files
and doing the initramfs set up but still using the gentoo
prefix and portage to compile and configure the kernel itself ready
for debian to do the packaging that gentoo seemed to be poor at
doing in practice.

I also looked at the electron builder package a bit to see if it could
help here.

Comments appreciated.

MF

The founder of Bedrock linux says that running gentoo and debian together
in it allows the dpkg-buildpackage of debian to be used by gentoo.......

This was the main problem I had with the out of tree kernels I tried making
in gentoo for the debian install.

See here:

https://www.linuxquestions.org/questions/bedrock-linux-118/using-bedrock-linux-with-gentoo-and-debian-4175656498/

I will give it a try on another machine I have that needs an extra part in
a while and see if it really works.

Linus Torvalds says that more weird hardware kernel fixes are coming our
way in the near future:
