Here are the conspicuous error messages I see just before the build fails: ... ... checking if TQt is available... no configure: WARNING: You are attempting to compile Trinity without the Trinity Qt Interface installed. Please install libtqtinterface-dev and try again! ... ... configure: creating ./config.status wrong input (flag != 4) at admin/conf.change.pl line 117, <> line 1456. Is there a libtqtinterface-dev package somewhere?
