Hi All,
I'm setting up a VirtualBox on a Win10 workstation. The guest OS is Debian Jessie. The guest gets 4098MB Ram and can use up to 4 cpu-cores. I'm setting this up with the idea to have a decent environment for armhf development (Raspberry Pi and Beaglebone Black).
Eclipse (Mars), armhf build-essential etc are installed, as is gdb-multiarch and Gtkmm-2.4.
I followed the setup as described in Derek Molloy's "Exploring Beaglebone"-book and various online tutorials/manuals.
Atm, my project compiles fine for armhf and is scp-ed to the target. :
#include "HelloWorld.h"
#include <gtkmm/main.h>
int main (int argc, char *argv[])
{
Gtk::Main kit(argc, argv);
HelloWorld helloworld;
//Shows the window and returns when it is closed.
Gtk::Main::run(helloworld);
return 0;
}
I can run this simple program by
paul@debian64:~$ ssh -X pi@192.168.1.100

pi@raspberrypi:~ $ cd temp/
pi@raspberrypi:~/temp $ ./RpiGtkmm
Hello World
Hello World
pi@raspberrypi:~/temp $ ^C
pi@raspberrypi:~/temp $
The graphic output is on the host Debian.
If I launch the program on the PRI the output is on the RPI 7" screen.
BUT : I intend to debug this program with eclipse running on the host. Starting a remote debugging session results in the programming breaking into a braekpoint at main. So far so good.
Once stepping over
Gtk::Main kit(argc, argv);
results in
(RpiGtkmm:2115): Gtk-WARNING **: cannot open display:
I tried different "solutions" I found on the internet, but to no avail...
Any tips/how-to's/tutorials on how to debug a X11 application on a remote machine from within a local eclipse would be highly appreciated!
Thanks in advance,
Paul
