Subject: meson-build-system's 'shrink-runpath phase fails for guile go files
Date: Thu, 15 May 2025 19:52:36 +0000

Hello,

I have been experimenting with using meson to manage some guile projects 
instead of autotools.

When I try to build it with guix it fails during 'shrink-runpath phase 
on .go files:

error: in phase 'shrink-runpath': uncaught exception:
wrong-type-arg "struct-vtable" "Wrong type argument in position ~A 
(expecting ~A): ~S" (1 "struct" #f) (#f)
phase `shrink-runpath' failed after 0.0 seconds

This is because ‘strip-runpath’ expects FILE to contain a DT_RUNPATH
section.  Failing that, the ‘runpath’ variable at gremlin.scm:417 is #f
and the (dynamic-entry-type runpath) calls right below fails with a
wrong-type-arg error.

A solution would be to fix ‘strip-runpath’ (patch below), though that
involves a world rebuild.

Another solution is to arrange so that ‘meson-build-system’ does not
touch .go files for this package, for instance by skipping the
‘shrink-runpath’ phase.

HTH,
Ludo’.

At first I thought it be 'only' a rebuild of the meson world, but I see 
now that (guix build gremlin) is also imported in gnu-build-system :(.

Yeah, that's what I have been doing but I think 'strip-runpath' could 
handle this case more gracefully. Also when there is both a guile c 
extension and go files I'd need to do custom things to apply 
shrink-runpath only for the .so files. This is of course doable but 
feels like a workaround until a proper fix is available.

Yes, it’s definitely a workaround, probably unavoidable until we land
the gremlin.scm fix.
