Guile version 3.0.4.38-64c894
I am on 64 bit arch linux, and I built guile3.0 from the AUR package
guile-git on Sep 12 2020
https://aur.archlinux.org/guile-git.git for the PKGBUILD (the config
options were practically non-existent).
I am writing to modules that dynamically link. DYNAMIC-LINK works in the
top level REPL, and when using DEFINE-MODULE.
When using the r6rs library syntax DYNAMIC-LINK is considered unbound and
the compilation fails.
The following is an example of the behavior with a minimally viable source
for reproducing the bug.
(library (fail-link (0 1))
(export link)
(import)
(define link dynamic-link))
What I get:
;;; note: source file /home/guy/guile-fail-link.scm
;;; newer than compiled
/home/guy/.cache/guile/ccache/3.0-LE-8-4.4/home/guy/guile-fail-link.scm.go
;;; compiling /home/guy/guile-fail-link.scm
;;; guile-fail-link.scm:4:2: warning: possibly unbound variable
`dynamic-link'
;;; compiled
/home/guy/.cache/guile/ccache/3.0-LE-8-4.4/home/guy/guile-fail-link.scm.go
ice-9/boot-9.scm:1669:16: In procedure raise-exception:
Unbound variable: dynamic-link
What I expect:
;;; note: source file /home/guy/guile-fail-link.scm
;;; newer than compiled
/home/guy/.cache/guile/ccache/3.0-LE-8-4.4/home/guy/guile-fail-link.scm.go
;;; compiling /home/guy/guile-fail-link.scm
;;; compiled
/home/guy/.cache/guile/ccache/3.0-LE-8-4.4/home/guy/guile-fail-link.scm.go
Additional information:
After I load the failing library I lose a bunch of top level definitions
and syntax. Like IMPORT is no longer recognized and I have to `,q`
in order to get the REPL in a usable state again.
I can just use DEFINE-MODULE, but honestly I like the r6rs syntax. Even
though imports between schemes differ enough (and FFI anyway)
that none of these libraries will end up being portable, I still like r6rs
library syntax.
If I need to find extra information for to help you all figure out what is
happening, please just let me know.
Also, thank you all for your hard work. I am excited to have this snappy
Guile 3 on my system now ;)

In r6rs libraries, only r6rs is available. You need to impor whatever bindings you need from the (guile) module

As Linus explained, you need to import the (guile) module.
(library (succeed-link (0 1))
(export link)
(import (guile))
(define link dynamic-link))
Works as intended, so I'm closing this bug. :-)
