Can't find unicode/ustring.h in test
I get this error during compilation:
make[3]: Entering directory '/home/hacksaw/src/dovecot-2.4.4/src/lib-language' CC test-lang-icu.o In file included from test-lang-icu.c:8: lang-icu.h:4:10: fatal error: unicode/ustring.h: No such file or directory 4 | #include <unicode/ustring.h> | ^~~~~~~~~~~~~~~~~~~ compilation terminated.
I have unicode 66, at least as far as Ubuntu is concerned.

Do you happen to have that header too? The header is in libicu-dev.

TL;DR: Nope.

I note in the NEWS that the external ICU lib was replaced, is this a left over from the old thing?

We'll have to check. Anyways, ubuntu package search claims libicu-dev should contain a bunch of headers. Not sure what ubuntu this is though.

Having looked at the icu 66 tag on their repo, I see that quite a bit was missing, so I ran:
sudo apt reinstall libicu-dev
And lo and behold, lots more files.
Why it was partial I do not know.
Anyway, I'm set for the moment, though the dependence is weird if you were trying to step away from it.
Aaaand compilation finished. :)
