Running test_ext2 in GitLab Continuous Integration environment fails like this: (test_ext2:6338): Gtk-WARNING **: 09:06:17.576: cannot open display: Running main() from test_ext2.cc Obviously the GitLab CI environment doesn't have an X11 display, but unfortunately this test case code requires one. Utils::execute_command() calls Gtk::Main::run() so requires a Gtk::Main object constructing and therefore an X11 display, even though this program never displays anything graphical. The call chain is: main() test_ext2.cc Gtk::Main::Main() gtkmm/gtk/src/main.ccg Gtk::Main::init() [1] gtk_init() gtk/gtk/gtkmain.c [2] which exits with a non-zero exit status when the DISPLAY environment variable is unset. Looked at deriving from Gtk::Main class and writing a replacement init() method which calls gtk_init_check() instead of gtk_init() but Gtk::Main::instance_ is a private member so not accessible in a derived class. Tried using Glib::MainLoop instead of Gtk::Main, but that doesn't initialise everything that Gtk::Main(), so the program crashes. Therefore use xvfb-run [3][4] to run this test program against a virtual X11 display when a real display isn't available. Coded execution of xvfb-run into this test program so that it can simply be executed on the command line like the other test programs, without having to remember to run "xvfb-run ./test_ext2 ...".
