OK. But I am not sure that helps me with my Debian-based problem. And hacking configure.ac files is not something I could do without an awful lot of work. When I ignore the configure output and just run make anyway, my build chokes on: qtterminal/qt_term.cpp:51:10: fatal error: QtCore: No such file or directory 51 | #include <QtCore> Note: different from Hernán's issue that chokes on #include <QApplication> On Mint (derived from Debian), looking in /usr/include/x86_64-linux-gnu/qt6/QtCore, I can see no header called QtCore! (Note the architecture-dependent path!) So I am clearly missing some dependency. "I am surprised that the various linux distros have diverged so much in how they split up Qt components for packaging." Indeed. I was reading Hernán's post and the list of stunningly obvious package names in openSUSE, and thinking "This looks so sensible!" (compared to the hunt-the-dependency dog's breakfast that is the Debian packaging of Qt). Bear in mind that Ubuntu is one of the most popular Linux distros. This may pose a troublesome issue for gnuplot going forward. It seems that the gnuplot build has /de facto/ been broken already - maybe some adaptive maintenance is needed? P.
