Gash-Utils ‘uname’ seems to be confused:

Linux ribbon 5.10.10-gnu #1 SMP 1 x86_64 GNU/Linux

The attached patch fixes it for me when I build it locally. Tested
against master, with an expanded guix.scm to build multiple versions.

I forgot to mention the ‘uname -s’ problem is hidden by the fact that we
always pass ‘--build’ to ‘configure’.  When we don’t do that,
‘config.guess’ runs and fails.

I wonder if this should be kept but changed to:

  (kernel-name? (or kernel-name? (not (or …))))

but I’m not entirely sure about the logic.

Gash folks, WDYT?

Thanks,

Indeed!  I noticed this same issue the other day.  Check out commit
2ee2e2721367cc242ceb0e4b364468870a87f0b4:

    https://git.savannah.nongnu.org/cgit/gash/gash-utils.git/commit/?id=2ee2e2721367cc242ceb0e4b364468870a87f0b4

I recommend that you take a look at the “wip-gcc-mesboot” branch.  It
has a couple “from the hip” changes that I made while looking at getting
Gash-Utils to handle more of the work in “commencement.scm”.  Last week
I was able to build to “gcc-mesboot1” with only Make, Diffutils, patch,
and Gzip (the first three were there before the “Scheme-only” bootstrap,
and Gzip saves writing “(delete 'compress-documentation)” over and
over).  Unfortunately, building Glibc after that is quite difficult.  To
do it with Gash-Utils, we would need (at least) to support redirects in
AWK and the “-t” and “-k” flags in sort.  For fun, I tried building Gawk
and Coreutils at this point (using the ancient versions that we
bootstrap with now).  That let me build Glibc, but then I hit a problem
with the “po2test.sed” script while building “gcc-mesboot”.  I tried
again with ancient GNU Sed, but the build seemed to hang during a
configure test.  I suspect adding Bash to the mix might fix it, but I
haven’t tried yet....

Back to the matter at hand: I’m closing this bug since it’s already been
fixed.  :)

We should add a pure Scheme gzip implementation, for instance using the
R6RS zlib implementation by Göran Weinholt in Industria.

Heheh, nice!  Anyhow, that looks like a promising path to me.

Thanks!  Any plan for a release?  We could upgrade the package in
‘core-updates’.

Bootar is already using that.  The problem with the Industria version is
that it only does decompression.  Fortunately, there’s an easy out here.
Gzip supports an uncompressed mode, so it would take only an hour or so
to write a “compressor” that just copies the data into Gzip format with
no compression.  (I’m hoping that XZ can do something similar so that
applying patches in “origin” records does not need to depend on the XZ
we use to unpack Guile.  Alternatively, we could add an option to
compress the patched sources with Gzip.)

I’ve been holding on to “gcc-mesboot” as the milestone that would
warrant a release.  On the other hand, I could try and reify the
progress so far into an improved “commencement.scm” that still uses some
old GNU utilities to build the last “mesboot” version of Glibc.  Either
way, it will take some time since (as you know) my attention is on
Disarchive right now.  :)

Oh I see.  And yes, we could add an option to turn off compression or
force use of gzip.
