Hello Jan,

Maybe it's related to this workaround:

Ah, I totally missed Phant0mas' wip-hurd-native branch...Yes, that's it

    phase `compress-documentation' succeeded after 0.5 seconds
    killing process 23791
    successfully built /gnu/store/za8qaq221bs231nlk12914334xmm1ilj-binutils-cross-boot0-2.34.drv
    /gnu/store/jk3kx5jwjs9m60svzk6sz79bf0w33l91-binutils-cross-boot0-2.34

Probably this is not a proper "fix" yet but at least it's identified and
has a workaround.  And there may be some other stuff there too; thanks!

Greetings,
janneke

Hurd bootstrap breaks guix building binutils-boot0@2.34

[Jan Nieuwenhuizen]

[-- Attachment #1: Type: text/plain, Size: 1107 bytes --]

Hi!

I have been looking at the recent work of Efraim and others wrt the Hurd
bootstrap.  On the Hurd, make-boot0 v4.3 did not work for me so I
reverted to make-boot0 v4.1 for now.  Now I'm stuck on building
binutils-boot0

    ./pre-inst-env guix build -e '(@@ (gnu packages commencement) binutils-boot0)'

It almost fully builds but fails with this error

    phase `compress-documentation' succeeded after 0.4 seconds
    error: cannot kill processes for uid `999': Operation not permitted
    guix build: error: cannot kill processes for uid `999': failed with exit code 1

after which my Hurd setup is broken; I haven't been able to build a new
package and had to reinstall my Hurd VM.  This error is reproducible for
me however: I tried again and broke my Hurd setup in exact the same way.
Any ideas what may be going wrong and how to fix this?

I am now looking to revert bootstrap-guile to v2.0
(https://lists.gnu.org/archive/html/guix-devel/2019-09/msg00106.html)
and possibly binutils-boot0 to v2.32.

Find my notes attached for how I am setting up Hurd development for Guix.

Greetings,
janneke

Re: Hurd bootstrap breaks guix building binutils-boot0@2.34

[Svante Signell]

Hello,

I did build the bootstrap binaries some time ago. They were corrupt. As well as
the pre-built ones that were available at 
http://berlin.guix.gnu.org/guix/bootstrap/i586-gnu/20190508

Down-grading from guile-2.2 to guile-2.0 did not improve the situation.

Now I have a project to cross-build Hurd from a GNU/Linux box: hurd-cross, using
the latest versions of the gnumach, hurd, glibc, gcc, etc. The built Hurd boots
and runs fine in a VM :) The project will soon be available on Savannah. From
there I will again cross-build the bootstrap binaries for Hurd, in due time
though. (Other packages, like ones not yet available natively, can also be
cross-built. That's an interesting extension.)

See 
https://lists.gnu.org/archive/html/guix-devel/2019-08/msg00198.html
https://lists.gnu.org/archive/html/guix-devel/2019-09/msg00000.html

https://lists.gnu.org/archive/html/guix-devel/2019-09/msg00225.html
for some of the efforts to make Guix work on GNU/Hurd.

Thanks!
(and sorry for top-posting)

Can you elaborate on that?  Do you know which packages/programs were
affected?

Ah, wait you mean:

> https://lists.gnu.org/archive/html/guix-devel/2019-09/msg00225.html

    I had to replace the following binaries in order to make
    ./pre-inst-env  guix build -K -e '(@@ (gnu packages commencement) gnu-make-
    boot0))' work:
    bash, cat, cp, gawk, grep, install, mv, rm, rmdir, tar, xz, cpp, guile, mkdir,

It seems these work for me.

For now it seems that the binaries I'm building from core-updates are
fine.

> Down-grading from guile-2.2 to guile-2.0 did not improve the situation.

Ah; yes I just found out as well :-)

Okay, that's a whole different route but starting from a working
situation can certainly help.  I'm going to try the Guix route some bit
more for now.
