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

using 'ld-okl4.lib.so' as 'ld.lib.so'
using 'pit_timer_drv' as 'timer'

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,

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.
