Wt

harfbuzz and pango issues ahead. I'm building against pango 1.44.3 and harfbuzz 2.5.3 on Arch Linux. These issues occurred while packaging the offical Arch Linux wt package.

The first problem with 4.1.0 is that it doesn't explicitly search and include the header dirs for harfbuzz. This results in:

By manually including those headers, I can progress a little bit further but it seems to be using deprecated APIs which are gone or changed in my version of pango:
