I use Slackware 14.1 multilib with latest Alien's packages:
I set my locale and user interface to Polish, but spellchecking dosen't work.
In Tools/Options/Language Settings/Writing Aids/Available language modules I don't see any language.
I tried deleting .config/libreoffice but no change.

Are sure all LibeOffice processes were closed before you deleted it?

Bundled dictionaries

I haven't it either there, but my spellchecker works. Check if you have "polish" in Tools->Language->For all text. If you have, selecting it there should be enough for spellchecker to work.

LibreOffice and Writer both have language settings. Those need to be set. I have never set anything in Writing Aids and have never had problems.

@Xsane Yep, all libreoffice processes were closed.

@Labinnah Yes, I have "Polish" selected everywhere (it was autodetected)

Do you guys have aspell installed?

Yes, I have aspell installed, but i don't think that this is important in this case.

According to this page: https://wiki.documentfoundation.org/...of_LibreOffice it is unknown (?) if there is any spell-checking capability in the Polish dictionary pack for LibreOffice. How weird.

How wouldn't they know?

Check if you have /usr/lib(64)/libreoffice/share/uno_packages/cache/uno_packages/some_tmp_dir/dict-pl.oxt. I found my libreoffice use this dictionary. However deleting this dir, make my libreoffice use dictionary from Alien Bob package. So spellchecker still working.

Well, here are my notes for LibreOffice dictionary use.

They are old and may no longer apply though.

_______________________
USING DICTIONARIES

To use the other dictionaries like en_GB.dic:
Format>Character>Language
or F7 Spell Checker
or Tools>Options>Language Settings>Languages>Locale Setting

Then they will show in menus for that document.
If you change it via Locale Setting the selection
will stick between session and be the 'default'
dictionary.

If you add 'User Defined', aka personal, dictionaries
with the same name as a global one, they will show
in the 'Add Word' menu if that language is selected.
If 'Default English USA' is selected added words go to
standard.dic. This is configurable in the 'Edit' dialog.

@Labinnah I have this dir, I found it was created by old install script. Actually I've been using upgradepkg for long time. Now I removepkg and then installpkg libreoffice and this dir is empty, but still spellchecking dosen't work

@Xsane I set Polish locale everywhere, but no success

My 2p.

Maybe try the original interface in USA English (i.e. try without the l10n package). I have had trouble to get the spell-checker to work when setting the l10n to the GB version instead of the common USA English. I no longer bother setting the interface to my local language... It's a bit weird but this spell-checking seems a common problem: http://ask.libreoffice.org/en/questi...ot-working-40/

I do not know how common the problem is, but I have never had trouble using British English with either LibreOffice or OpenOffice. It is possible that some languages are not be as well supported as English, but I have no idea if that is actually the case. With English locales, it is a matter of installing the correct dictionary. If it does not work with any dictionaries, my guess would be a problem with either configuration or a missing component, either not installed by the user or a fault in the distribution's package.

With Polish? No idea of the quality of Polish language packages.Try aspell, hunspell and whatever else there is, until you (hopefully) find one that works. System locale settings do not affect Libre/OpenOffice. They only care about which locales are set in that application's settings. If you cannot get LibreOffice to work, try OpenOffice.

I have been baffled by this for some time myself, for Greek spelling, until I made it work, but YMMV. My assumption has been that the included language packs had incorporated any preexisting dictionaries and thesauri, and that the problem therefore was not related with installing an .oxt file. After trying several suggestions without success, I decided to install the dictionary I always installed in the past, and lo and behold it worked! I didn't research it any further, so I can't offer any answer as to why it behaves like this, but empirically it does :-)

I installed hunspell from slackware repo and spellchecking works!
