Looks like wayland has struck, this is: cat /etc/debian_version (new way of determining version) 10.1 Whats next? locate says theres glib-2.0 installed. /usr/lib/arm-linux-gnueabihf/glib-2.0, and /usr/lib/arm-linux-gnueabihf/libglib-2.0.so.0 Is it useable? Will a fresh git clone help, that one's about 3 weeks old. Have a shot at a fresh copy: And I get to the exact same bailout msg from ./configure --with-realtime=uspace checking for module installation directory... configuring for run-in-place /media/pi/slash/linuxcnc-dev/rtlib checking for glib... configure: error: no -- required until somebody makes glib optional So, what do I do next?
