Hi,

I am a researcher at Inria France and am presently exploring Genode as a potential option to perform hands on with Sel4. I am relatively new to Genode and having an issue while installing it.

Here is the issue:

I am trying to install Genode on Ubuntu (16.04 LTS) running within a container. I am able to successfully see through all the installation steps.

However, when I issue the final command: make -C build/x86_32 KERNEL=okl4 run/demo, I get this following error.

make[1]: Leaving directory '/Genode/genode/build/x86_32'
genode build completed

I did install libsdl1.2-dbg. Clearly, I do not have a display connected, as I am trying to run it from within a container. Could you please help me with this issue?

Thank you in advance!

Yours sincerely,

Subhadeep

I'd suggest you to comment
QEMU_OPT += -display sdl
out from the etc/build.conf, and add an option like
QEMU_OPT += -display vnc=<IP address>:<display>

This would activate QEMU built-in VNC server. You would be able to access the Genode display via a VNC client, connecting to a <IP address>:<display> VNC display.

I'm connecting to my development Linux system from my main OS, via SSH. When I need to run binaries, to test them, I start the corresponding run script. I see the logs in my SSH window. When I need to see the Genode screen, I just start the VNC viewer. The only disadvantage is that the mouse cursor in a VNC client is displaced, relative to Genode mouse cursor. I still did not worked this problem around. Also, there exists an option to run QEMU screen, or a SDL window in Genode/Linux, remotely via X11 remote connection (you need your DISPLAY env. variable to point to your local X11 display). But I did not managed to make it working successfully, because when I run it from an SSH session, it tries to use the "fbcon" SDL backend. Trying to set SDL_VIDEODRIVER env. variable to "x11" doesn't help here.
