Missing .so for guile-aiscm

Missing .so for guile-aiscm

[Jonathan Frederickson]

Hi all - I'm trying out OpenCV via AIscm in Guix using the guile-aiscm
package, and I'm having some trouble. When I attempt to load one of the
AIscm modules, I get an error about a missing native library:

#+begin_src
jfred@lambdacrypt ~$ guix shell guile guile-aiscm
hint: Consider passing the `--check' option once to make sure your shell does not clobber environment
variables.

bash: alias: -p: not found
jfred@lambdacrypt ~ [env]$ guile

While compiling expression:
In procedure dlopen: file "libguile-aiscm-util.so", message
"libguile-aiscm-util.so: cannot open shared object file: No such file or
directory"
#+end_src

I've just updated to the latest Guix revision as of now with the same
result, so it looks like it's not something that was broken in a
previous revision and since fixed.

It seems like installing the library into this temporary shell may not
have installed its native components or something? I feel like I must be
doing something wrong here. Any help would be much appreciated!

Ah, hmm - so I think I partly figured out why. (At least, enough to move
forward with what I'm trying to do.) The Guile package in Guix isn't
configured to look in GUILE_EXTENSIONS_PATH for native extensions. I
managed to work around this by doing this in a manifest for my project:

#+begin_src scheme
(define-public guile-search
  (package
    (inherit guile-3.0)
    (native-search-paths
     (list (search-path-specification
            (variable "GUILE_EXTENSIONS_PATH")
            (files (list "lib/guile/3.0/extensions")))))))
#+end_src

That said... is there a reason the Guile package doesn't already look
here by default?
