 dictionary with a \.aff affix file"

Hello, Emacs.

When I run the test suite with make check, I get 25 successes in
test/lisp/textmode/ispell-tests/ispell-tests.log.  Each of these has the
same error message, "Can't find Hunspell dictionary with a .aff affix
file".

I don't know what a .aff file is, but it seems like my setup is missing
one.  Despite this, surely ispell-tests.el should cope with this
deficiency, rather than emitting 25 error messages.

Are you saying that you have the Hunspell executable, but not its
dictionaries?  What happens if you invoke Hunspell from the shell
prompt -- does it work or does it show some error message?

If your Hunspell installation is workable, you should have a
/usr/share/hunspell directory with *.aff files.  If they are missing,
either install them or remove the Hunspell executable.  The Emacs test
suite is not supposed to cope with installations that don't work, so
showing error messages is OK in that case.

If all of the above doesn't resolve your problem, please show the
exact error messages, with everything else that the test displays
(which you should have done in the first place, of course).

FWIW, I've just tried renaming the Hunspell executable, and the test
suite correctly skipped the relevant ispell tests.  So if Hunspell is
not installed, I don't expect any error messages.

Hello, Eli.

Thanks for such a quick reply!

Yes, that is indeed the case.  The Hunspell installation script on Gentoo
installs the dictionaries it is specifically asked to install, and if
none are requested, none are installed.  No sensible default is used.
This may be a Gentoo bug.

I get the error message:

    Can't open affix or dictionary files for dictionary named "en_GB".

I have what is arguably a valid installation, even though not useful.  I
tried reinstalling it, and got no warning message about the lack of
languages.

After deinstalling hunspell ...., I get a different message in
ispell-tests.log:

    (error "No Ispell process to read output from!")

, but I suspect that will go away as soon as I reboot.

Maybe later, after I've rebooted.

OK, thanks.
