"undefined reference to unac_debug_callback": I think this was reported 4 years ago here: rt.cpan.org/Public/Bug/Display.html?id=124815 — Håkon Hægland

The workaround worked for me on Windows 11, see answer below — Håkon Hægland

undefined reference to unac_debug_callback

This issue has been reported earlier here: https://rt.cpan.org/Public/Bug/Display.html?id=124815

As commented by SREZIC in that thread: Adding

 #define HAS_VPRINTF

to unac.c seems to workaround the problem. I tested this on Windows 11, Strawberry perl version 5.32.1 and this works fine:

Downloaded the tar ball here: https://cpan.metacpan.org/authors/id/L/LD/LDACHARY/Text-Unaccent-1.08.tar.gz
Unpacked and extracted the tar ball

Cd into the unpacked directory, and edit unac.c. Like the following patch shows:

diff --git a/unac.c b/unac.c
index 20863d2..2c63fc2 100644

Run perl Makefile.PL; gmake; gmake test; gmake install:
