Package: libpango1.0-dev Version: 1.46.2-2 Severity: normal Dear Maintainer,
I don't know in which version it happened, but the header files no longer define the PangoFcFontClass type (and PangoFcFontMapClass), which makes accessing the documented public members inside and subclassing impossible. According to the docs (e.g. https://developer.gnome.org/pango/stable/PangoFcFont.html), to implement a new fc-backend requires subclassing both PangoFcFontMap and PangoFcFont, which is no longer possible in 1.46, breaking all third-party renderers (e.g. ours, which uses pango to implement opengl rendering in games). -- System Information: Debian Release: 10.6 APT prefers stable APT policy: (990, 'stable'), (500, 'unstable-debug'), (500, 'testing-debug'), (500, 'stable-updates'), (500, 'stable-debug'), (500, 'unstable'), (500, 'testing'), (1, 'experimental-debug'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386, x32 Kernel: Linux 5.8.16-050816-generic (SMP w/8 CPU cores) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_DK.UTF-8, LC_CTYPE=en_DK.UTF-8 (charmap=UTF-8), LANGUAGE=en_DK.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages libpango1.0-dev depends on: ii gir1.2-pango-1.0 1.46.2-2 ii libcairo2-dev 1.16.0-4 ii libfontconfig1-dev 2.13.1-2 ii libfreetype6-dev 2.10.2+dfsg-4 ii libfribidi-dev 1.0.5-3.1+deb10u1 ii libglib2.0-dev 2.66.2-1 ii libharfbuzz-dev 2.6.7-1 ii libpango-1.0-0 1.46.2-2 ii libpangocairo-1.0-0 1.46.2-2 ii libpangoft2-1.0-0 1.46.2-2 ii libpangoxft-1.0-0 1.46.2-2 ii libthai-dev 0.1.28-3 ii libx11-dev 2:1.6.7-1+deb10u1 ii libxft-dev 2.3.2-2 ii libxrender-dev 1:0.9.10-1 ii pango1.0-tools 1.46.2-2 ii pkg-config 0.29-6 libpango1.0-dev recommends no packages.
