Just a few clues I’ve found about running the same binary without a GUI:
- GTK supports running a program without display: http://library.gnome.org/devel/gtk/2.12/gtk-General.html#gtk-init-check. This doesn’t tell if it’s possible in wxWidgets though.
I see it calls gtk-init-check in wxApp::Initialize.
I can subclass Initialize, call the original one while suppressing the error message and ignore the return value. It seems to be working.
This is working. A few more things and I’ll upload it.
We’ll need to tell people to install the GTK libraries. Do you remember the apt-get command to install GTK, and can you install it without having a GUI installed?
