As this causes the following error when computing a cross-compilation
derivation for r-minimal and related packages.

I think this is coming from the string appearing in the sources section of the
derivation, but not being a valid store path.

* gnu/packages/statistics.scm (r-minimal)[arguments]: Split string involving
/gnu/store.

It would imply rebuild many packages, no? master, staging or
core-updates?

It does, my plan was/is to ask Ricardo if he could maybe include it when
pushing the next big batch of r related changes?

I am preparing a Bioconductor upgrade, so it could be part of it.

Good spot, I've updated the patch/commit message.

But it's this:

→ guix build --target=aarch64-linux-gnu r-minimal
guix build: error: path ‘/gnu/store/[^-]+-glibc-[^-]+-static’ is not valid

I'm not sure why this seems to only affect cross derivations. It's not
the only problem that's happened for cross derivations though, so it
might be good to expand the linting to cover them (maybe even for just
one common target like aarch64-linux-gnu).

Thanks,

Chris

As this causes the following error when computing a cross-compilation
derivation for r-minimal and related packages:

guix build: error: path ‘/gnu/store/[^-]+-glibc-[^-]+-static’ is not valid

I think this is coming from the string appearing in the builder and thus the
sources section of the derivation, but not being a valid store path.

Interesting bug!

I pushed a fix and explanation:

Toggle snippet (26 lines)
commit 3bd4b92f55f40119349e39902a9b800de98040d2

build-system/gnu: Turn #:phases into a gexp when cross-compiling.
Previously, we'd get this error:
$ guix build --target=aarch64-linux-gnu r-minimal -d --no-grafts
guix build: error: path ‘/gnu/store/[^-]+-glibc-[^-]+-static’ is not valid
This is because the sexp would be passed as an input of the surrounding
gexp in 'gnu-cross-build', and thus
"/gnu/store/[^-]+-glibc-[^-]+-static" would be interpreted as a source
file name, as in this example:
scheme@(guix gexp)> #~(foo #$(list 'whatever "/gnu/store/[^-]+-glibc-[^-]+-static"))
$11 = #<gexp (foo #<gexp-input (whatever "/gnu/store/[^-]+-glibc-[^-]+-static"):out>) 7f098badec30>
scheme@(guix gexp)> (gexp-inputs $11)
$12 = (#<gexp-input "/gnu/store/[^-]+-glibc-[^-]+-static":out>)
Fixes <https://issues.guix.gnu.org/59073>.
Reported by Christopher Baines <mail@cbaines.net>.
* guix/build-system/gnu.scm (gnu-cross-build): When PHASES is a pair,
pass it through 'sexp->gexp'.

That said, this code is bogus:

1. We should refrain from using non-literal strings as patterns in
‘substitute*’.

2. We should call ‘%store-directory’ from (guix build utils) instead
of hardcoding “/gnu/store”.

Both of these should be fixed at some point.

Thanks,
Ludo’.

What does it mean “non-literal string” here?

A string that is not a literal (or constant, if you prefer).

This is OK:

(substitute* f
((".*") …))

This is not:

(substitute* f
(((string-append "." (star))) …))
