I get "doesn't work" is never enough. It sure works for me. Works for a thousand other people. Only you can debug it. For example, is libharfbuzz-gobject.so.o in ~/HB/lib? If yes, is your LD_LIBRARY_PATH correctly set, try strace, does it look there, etc. <div class="HOEnZb"><div class="h5"> > ** (kt.py:15896): WARNING **: Failed to load shared library > 'libharfbuzz-gobject.so.0' referenced by the typelib: > libharfbuzz-gobject.so.0: cannot open shared object file: No such file or > directory > > and sometimes a bunch of other errors after it > > On Tue, Aug 2, 2016 at 5:31 PM, Behdad Esfahbod <<a href="mailto:behdad@behdad.org">behdad@behdad.org</a>> wrote: >> >> "make uninstall" >> >> On Tue, Aug 2, 2016 at 2:28 PM, Kelvin Ma <<a href="mailto:kelvinsthirteen@gmail.com">kelvinsthirteen@gmail.com</a>> >> wrote: >> > I want to move my harfbuzz installation out of root space and into user >> > space, but I can't find uninstall info anywhere.
