sbcl/glibc troubles

[Benjamin Slade]

I'm trying (ultimately) to install "shuffletron" [
http://vintage-digital.com/hefner/software/shuffletron/ ], a common lisp
music player, but I'm getting stuck on one of its dependencies,
"osicat", with the following error from `(ql:quickload "osicat")` under sbcl:

<-------------------------------------------------->
; Loading "osicat"
..

#<THREAD "main thread" RUNNING {10005585B3}>:

<-------------------------------------------------->

I have glibc-2.28 installed however.  Is there a way to get it to
associate with this instead of (for whatever reason) with glibc-2.27?

This is the typical issue you'll always run into when using Common Lisp with
foreign libraries.
I know this very well since I'm working on packaging other Common Lisp programs
like Next browser and cl-torrents.

CFFI is the Common Lisp C Foreign Function Interface.  It looks up libraries in
/usr/lib... by default.  You want to change this path in
`cffi:*foreign-library-directories*`.  Ideally, you would add the canonical path
of all the required libraries there.  If you want to go the lazy way, simply
install the libraries in your user profile and add ~/.guix-profile/lib to this
variable.

Basically all you need is to call

--8<---------------cut here---------------start------------->8---
(ql:quickload :cffi)
(push (format nil "~a/.guix-profile/lib/" (uiop:getenv "HOME")) cffi:*foreign-library-directories*)
--8<---------------cut here---------------end--------------->8---

before calling quickload.
Note that the trailing "/" in the library path is important.

Hope that helps!

I must not be doing something right, because it still complains about
not being able to find GLIBC_2.28. I notice it also says:

(CFFI::FL-ERROR "Unable to load foreign library (~A).~%  ~A" :LIBOSICAT #<(SIMPLE-BASE-STRING 422) Error opening shared object "/home/slade/.cache/common-lisp/sbcl-1.4.4-linux-x64/home/slade/quicklisp/dists/quicklisp/software/osicat-20180228-git/posix/libosicat.so":

Sorry, I misread the error message.
Your error is unrelated I think, although you might need the aforementioned
trick later.

The problem is with libosicat.  How did you install it?
It seems to me that it came pre-compiled as a binary.
You can check this with

  ldd /home/slade/.cache/common-lisp/sbcl-1.4.4-linux-x64/home/slade/quicklisp/dists/quicklisp/software/osicat-20180228-git/posix/libosicat.so

(Find `ldd` in the gcc-toolchain package.)

If I'm right, you need to package libosicat for Guix first so that the linker
knows about the right Glibc, etc. which paths are different on Guix compared to
most traditional distributions.

Once you get libosicat compiled correctly (check the output of ldd to make sure
there is no missing library) it should work fine.  If not, try to customize
cffi:*foreign-library-directories*.

Let me know if you need help with osicat.
