I've now created a 'sid' virtualbox guest (not just for this thread, I needed to anyway
). I installed the sid CodeLite 10.0, created a new workspace and new wx gui project (wxframe + wxcrafter). After building it runs normally; that's either with or without the 'Use CodeLite's built-in terminal emulator' box checked. FWIW I have the basic xfce4 install, so the default emulator is xfce4-terminal.
What am I doing that's different from you?
Did you build your own CodeLite? If so, which?
Is your project different in some way? If so, what happens if you create one as I did?
