Hello Vincent, +cc freetype-devel
Yes, I'm working on a local branch and I've sent an experimental patch to the mailing list some weeks ago. Here's a more recent version rebased on top of latest changes. There is a list of TODO() at the end of the meson.build file if you're curious. Next step will be a proper "meson dist" that does the right thing. Then introduce regression/unit-testing. Hope this helps, - David Le ven. 24 juil. 2020 à 06:26, Vincent Torri <vincent.to...@gmail.com> a écrit : > hello > > if i'm not mistaken, you said that you would add meson as build > system.

From 63b49d6dd47df4f90cd08bc41e7ce9524dfe926d Mon Sep 17 00:00:00 2001 From: David Turner <david.turner....@gmail.com> Date: Sun, 17 May 2020 18:45:41 +0200 Subject: [build] Add Meson build project files. This adds a few files to build the FreeType 2 library with the Meson build system: - meson.build: top-level Meson build file for the library. - meson_options.txt: user-selectable options for the build. These can be printed with 'meson configure', and selected as 'meson setup' or 'meson --reconfigure' time with -D<option>=<value>. - builds/meson/ft{config,option}.h.in: template versions of ftconfig.h and ftoption.h to be used by the Meson build. These are processed by Meson, which will turn #mesondefine statements into #define / #undef depending on build configuration.
