Because it doesn't work? Here I tested with the simplest possible program, from sample.py
#!/usr/bin/python3.5 # -*- coding: utf-8 -*- import sys import array from os import environ environ['LD_LIBRARY_PATH'] = '/usr/local/lib/girepository-1.0' environ['GI_TYPELIB_PATH'] = '/usr/local/lib/girepository-1.0' from gi.repository import HarfBuzz as hb from gi.repository import GLib fontdata = open(sys.argv[1], 'rb').read () text = sys.argv[2] # Need to create GLib.Bytes explicitly until this bug is fixed: # https://bugzilla.gnome.org/show_bug.cgi?id=729541 blob = hb.glib_blob_create (GLib.Bytes.new (fontdata)) face = hb.face_create (blob, 0) del blob font = hb.font_create (face) upem = hb.face_get_upem (face) del face hb.font_set_scale (font, upem, upem) hb.ot_font_set_funcs (font) buf = hb.buffer_create () class Debugger(object): def message (self, buf, font, msg, data, _x_what_is_this): print(msg) return True debugger = Debugger() hb.buffer_set_message_func (buf, debugger.message, 1, 0) hb.buffer_add_utf32 (buf, array.array('I', text.encode('utf-32')), 0, -1) hb.buffer_guess_segment_properties (buf) hb.shape (font, buf, []) del font infos = hb.buffer_get_glyph_infos (buf) positions = hb.buffer_get_glyph_positions (buf) for info,pos in zip(infos, positions): gid = info.codepoint cluster = info.cluster x_advance = pos.x_advance x_offset = pos.x_offset y_offset = pos.y_offset print("gid%d=%d@%d,%d+%d" % (gid, cluster, x_advance, x_offset, y_offset)) This works correctly when Harfbuzz is installed in usr/local/. However, if I sudo make uninstall, run ./configure --with-gobject --enable-introspection --prefix=/home/kelvin/HB, and make install, and change the environment variables to environ['LD_LIBRARY_PATH'] = '/home/kelvin/HB/lib/girepository-1.0' environ['GI_TYPELIB_PATH'] = '/home/kelvin/HB/lib/girepository-1.0' The script crashes like this: ~$ ./hbt.py NocturnoDisplay-Bk.otf effectiveness ./hbt.py:11: PyGIWarning: HarfBuzz was imported without specifying a version first.
