Subject: bug#38838: 'whatis' doesn't work
Date: Mon, 6 Jan 2020 19:05:06 +0100 [thread overview]
Message-ID: <CAJ3okZ3p+319_nm2p48APK0Sz24=+dwa8GYtZFmHMp=RTYknJQ@mail.gmail.com> (raw)
In-Reply-To: <20191231215941.jpr57n5kqp6x3km6@zdrowyportier.kadziolka.net>
Dear,
I confirm that something appears unexpected with the command 'whatis'.
Below, using Guix 3a695c01d7ee18f30f22df53f3c44dfac04017f1, and running
`guix environment --ad-hoc man-db man-pages --pure` then let output the
internal debugging information (option '-d'). See below.
Everything seems pointing to the correct path, so maybe it should come
from the 'index.db' file.
Well, let manually build an index, by first download the necessary files
with (outside the environment):
guix build man-pages --no-grafts --check -K
then inside the environment:
mandb -c /tmp/guix-build-man-pages-5.04.drv-0/man-pages-5.04
and now,
whatis -M /tmp/guix-build-man-pages-5.04.drv-0/man-pages-5.04 memcpy
works as expected.
Last, note that using the 'apropos/whatis' binary from Debian and the
path of the temporary profile (guix environment), I get:
--8<---------------cut here---------------start------------->8---
/usr/bin/apropos -M
/gnu/store/hg02c2i5ycd4g0498xwgsbxyikz1bvf1-profile/share/man memcpy
memcpy (3) - copy memory area
wmemcpy (3) - copy an array of wide-characters
/usr/bin/whatis -M
/gnu/store/hg02c2i5ycd4g0498xwgsbxyikz1bvf1-profile/share/man memcpy
memcpy: nothing appropriate
--8<---------------cut here---------------end--------------->8---
I do not know if this report helps and if the index is the culprit.
What do you think?
All the best,
simon
