The error reported by `invoke' isn't accurate, and mutes important
output from the program invoked.
Example of a failed tar extraction:
--8<---------------cut here---------------start------------->8---
/gnu/store/xlj36j9dw581iah51iyjgi75iikrj55h-module-import/guix/build/utils.scm:616:6: In procedure invoke:
Throw to key `srfi-34' with args `(#<condition &invoke-error [program: "tar" arguments: ("xf" "/gnu/store/yanfzfi7rdyf5scf5h65xbkn7xg0nnbn-docbook-dsssl-doc-1.79.tar.bz2" "--strip-components=1" "-C" "/gnu/store/rw7yzjk1wffza65z6l6rnn25qg97jvh1-docbook-dsssl-doc-1.79" "docbook-dssl-1.79/doc") exit-status: 127 term-signal: #f stop-signal: #f] 68fc80>)'.
--8<---------------cut here---------------end--------------->8---
While reproducing the same error in an containerized environment,
calling the command directly yields:
--8<---------------cut here---------------start------------->8---
tar xf yanfzfi7rdyf5scf5h65xbkn7xg0nnbn-docbook-dsssl-doc-1.79.tar.bz2 --strip-components=1 -C $PWD docbook-dssl-1.79/doc
tar: docbook-dssl-1.79/doc: Not found in archive
tar: Exiting with failure status due to previous errors
maxim@apteryx /tmp/docbook-dsssl-doc [env]# echo $?
2
--8<---------------cut here---------------end--------------->8---
Two observations:
1. invoke's reported exit status was wrong (127 rather than 2)
2. The useful error message "docbook-dssl-1.79/doc: Not found in
archive" was masked.

More problematic even, it seems "invoke" can't do everything that
"system*" can?
For example, the following package builds fine:
--8<---------------cut here---------------start------------->8---
(define-public docbook-dsssl-doc
(package
(name "docbook-dsssl-doc")
(version "1.79")
(source (origin

(uri (string-append "mirror://sourceforge/docbook/"
name "/" version "/"
name "-" version ".tar.bz2"))

Did you check to see if the extraction actually succeeded?
In this case, I don't see how it could have. When using 'tar' from
within 'trivial-build-system', you need to add 'bzip2' to PATH, or else
'tar' will fail because it can't find 'bzip2'. There are many examples
of setting PATH in (gnu packages fonts).
Because of the way you are using 'system*' here without the usual
'zero?' wrapped around it, the numeric result code is returned as the
result of the builder, and all numbers (even 0) are considered true in
Scheme. So, this build will always succeed, ignoring errors from 'tar'.

Changing 'system*' to 'invoke' allowed you to see that something went
wrong.

I think what happened is that 'tar' actually failed in two different
ways. In the first case, where the result code was 127, it failed
because 'bzip2' was not found in PATH. In the second case, it failed
because "docbook-dssl-1.79/doc" was not found in the archive.
Or at least that's my guess.

Mark

OK. I now understand that the trivial-build-system does exactly nothing
for us, so it doesn't even sets the "PATH" environment variable. This
wasn't obvious to me, thank for pointing it out!
> Changing 'system*' to 'invoke' allowed you to see that something went
> wrong.
Right, my confusion stemmed from the unset PATH variable; tar itself
would return exit code 127 (command not found) in the
trivial-build-system, but I couldn't reproduce directly in a
containerized guix environment because there is a profile generation
hook there which does set the PATH.

It seems that the "system" and "system*" commands of Guile as well as
our "invoke" do preserve the stdout/stderr, as when testing it manually
I can see the useful "sh: tar: command not found" message:

Could it be preserved? It'd be very useful when debugging :)

I've investigated a bit, and as far as I can see by reading guix
sources, the build log output would be displayed and any error reported
by the `process-stderr' procedure in (guix store). This procedure
behavior seems to depend closely on that of the guix daemon (server), so
the problem could lie on the daemon side as well, so that's where I'll
try digging next.

Hello,
I think my original observations must have occured in Emacs while using
Geiser. It has to do with what (current-output-port) is bound to in the
REPL (see: https://github.com/jaor/geiser/issues/83).
I'm closing, as I haven't seen this issue in almost 2 years when using
Guix from the command line.
