'guix package' commands keep giving me this output:

The following environment variable definitions may be needed:
   export GUILE_LOAD_COMPILED_PATH="/home/taylan/.guix-profile/lib/guile/2.0/site-ccache:/home/taylan/.guix-profile/share/guile/site/2.0${GUILE_LOAD_COMPILED_PATH:+:}$GUILE_LOAD_COMPILED_PATH"

I already have said paths in my $GUILE_LOAD_COMPILED_PATH.  In fact, I
get the output even if I define it to have *solely* those two paths.

taylan@T420:~$ guix package -r nano
[... snip ...]
75 packages in profile
The following environment variable definitions may be needed:
   export GUILE_LOAD_COMPILED_PATH="/home/taylan/.guix-profile/lib/guile/2.0/site-ccache:/home/taylan/.guix-profile/share/guile/site/2.0${GUILE_LOAD_COMPILED_PATH:+:}$GUILE_LOAD_COMPILED_PATH"
taylan@T420:~$ echo $GUILE_LOAD_COMPILED_PATH

Weird, I don’t seem to have this problem.

Could you add a few ‘pk’ in ‘search-path-environment-variables’ in (guix
scripts package) to see what’s happening?

Thanks,
Ludo’.

After some poking around, I found the issue; it's the following in the
guix-0.12.0 recipe:

    (wrap-program (string-append out "/bin/guix")
      `("GUILE_LOAD_PATH" ":" prefix (,path))
      `("GUILE_LOAD_COMPILED_PATH" ":" = (,path)))

As you see, it sets GUILE_LOAD_COMPILED_PATH to an absolute value rather
than prefixing it.  So whenever I execute 'guix package ...' from the
shell, the installed wrapper overrides my correct value of
GUILE_LOAD_COMPILED_PATH with something insufficient.

FWIW, it overrides it with the following (split for readability):

"/gnu/store/f4pw2jr2ial53awa34rjj3wb4b4k3nag-guile-json-0.6.0/share/guile/site/2.0:
/gnu/store/y9k9l62cf8hhr5m3np3756swrbxws0dl-guile-ssh-0.10.2/share/guile/site/2.0:
/gnu/store/iyvx2rpyndi3k7dzbl4jnv7k6ddkx88a-gnutls-3.5.8/share/guile/site/2.0"

Should the 'wrap-program' call simply use 'prefix' instead of '='?  I'm
not sure if there's a reason it uses '='.

Taylan

Oh, good catch!

Above the ‘wrap-program’ call, there’s this comment:

        ;; Ignore user settings so that a bogus
        ;; GUILE_LOAD_COMPILED_PATH does not prevent use of
        ;; 'guix', notably when it contains entries pointing to
        ;; incompatible .go files as reported at
        ;; <https://lists.gnu.org/archive/html/guix-devel/2016-03/msg01261.html>.

Since 2.0.12, Guile skips invalid .go files, so this problem is gone.
So I think you can go ahead and change '= to 'prefix there.

Thanks!

Ludo’.

Duh, missed that. :-)

Done and pushed.

Thanks for the assistance!
