No, DiapDealer, I did not set anything, I executed brutally the instructions which had worked with Kubuntu 17.04 (in docs "Building_on_cutting_edge_Linux.md"). In effect, after upgrading to 17.10, I tried installing sigil from synaptic, and then (because nothing changed) I have recompiled from modified sources of Sigil 0.98, and all was right, except at command "sudo make install" I got a lot of strange messages:
Code:
-- Up-to-date: /a/different/install/prefix/lib/sigil/sigil
-- Up-to-date: /a/different/install/prefix/bin/sigil
-- Up-to-date: /a/different/install/prefix/lib/sigil/libhunspell.so
-- Up-to-date: /a/different/install/prefix/lib/sigil/libsigilgumbo.so
-- Up-to-date: /a/different/install/prefix/share/applications/sigil.desktop
-- Up-to-date: /a/different/install/prefix/share/pixmaps/sigil.png
and so
