Re: [Plplot-general] PLPLOT-5.14.0: building cairo.dll fails (Windows 10)

Hi all, I ran into the same problem a couple of weeks ago. It is in fact a bug in pango 1.43.0 which uses meson as buildsystem instead of autotools, and the pkg-config issue was introduced in the transition. I reported this as a bug <https://gitlab.gnome.org/GNOME/pango/merge_requests/22#note_390137> and submitted a patch <https://gitlab.gnome.org/GNOME/pango/merge_requests/38>, which is now in master and should end up in 1.44 (or possibly in 1.43.1 if this ever gets released). In the meantime, the problem can be fixed by executing: echo "Requires: gobject-2.0" >> /mingw64/lib/pkgconfig/pango.pc followed by building plplot… The cairo backend should build fine then.

The fortran mathematics and the GTK gui are already running as an 64-bit executable.
