Hi, here on the same track, trying to use recoll on guix foreign distro:
1) recoll log.txt [...] :2:index/indexer.cpp:405::ConfIndexer::createAspellDict: aspell buildDict failed: aspell dictionary creation command failed: /gnu/store/mgcicm6phq4971195znrrv804r89sb0b-aspell-0.60.8/bin/aspell --lang=en --encoding=utf-8 create master /home/ci/.recoll/aspdict.en.rws One possible reason might be missing language data files for lang = en. Maybe try to execute the command by hand for a better diag. [...] 2) ~$ guix package --list-installed=aspell\* aspell-dict-es 1.11-2 out /gnu/store/0jzq0qb1ljq973h403japslq5kvsr13g-aspell-dict-es-1.11-2 aspell 0.60.8 out /gnu/store/mgcicm6phq4971195znrrv804r89sb0b-aspell-0.60.8 aspell-dict-uk 1.4.0-0 out /gnu/store/7b4925ih5xgfkscd5zd0bp57ms62d6j6-aspell-dict-uk-1.4.0-0 aspell-dict-de 20161207-7-0 out /gnu/store/r4gmz8ff5z26kswk435rg47pl9kpx59x-aspell-dict-de-20161207-7-0 aspell-dict-en 2020.12.07-0 out /gnu/store/bssgajl900xbki758ainw9kimza9jxmi-aspell-dict-en-2020.12.07-0 aspell-dict-ca 2.5.0 out /gnu/store/ln7c0ibs6li92r12yraqcwwn3l29psa6-aspell-dict-ca-2.5.0 Trying to run the aspell, as the recoll log.txt: 3) ~$ aspell --lang=en --encoding=utf-8 create master $HOME/.recoll/aspict.en.rws Error: The language "en" is not known. This is probably because: the file "/gnu/store/mgcicm6phq4971195znrrv804r89sb0b-aspell-0.60.8/lib/aspell-0.60/en.dat" can not be opened for reading. Find does not seem to find anything: 4) ~$ find $(guix build aspell-dict-en) -name \*cset 5) ~$ find $(guix build aspell-dict-en) -name \*cmap as vapnik spaknik stated, there seems to be no "file "/gnu/store/mgcicm6phq4971195znrrv804r89sb0b-aspell-0.60.8/lib/aspell-0.60/en.dat" but those are on the language package itself: 6) ~$ find $(guix build aspell-dict-en) -name \*.dat /gnu/store/bssgajl900xbki758ainw9kimza9jxmi-aspell-dict-en-2020.12.07-0/lib/aspell/en_phonet.dat /gnu/store/bssgajl900xbki758ainw9kimza9jxmi-aspell-dict-en-2020.12.07-0/lib/aspell/en_affix.dat /gnu/store/bssgajl900xbki758ainw9kimza9jxmi-aspell-dict-en-2020.12.07-0/lib/aspell/en.dat (that last is not "/gnu/store/mgcicm6phq4971195znrrv804r89sb0b-aspell-0.60.8/lib/aspell-0.60/en.dat" (see 3) I hope it helps! francisMB
