Hi,
Thank you for your quick response!
However, even after trying on it for the last couple of last I could
not make it work (clearly shows that I am a newbie in Genode). The
good part is I am able to by pass the problem by installing Genode in
a (ubuntu) virtual machine instead of a container. I successfully
launched the demo for okl4 from there. Launching sel4, however, does
not appear to be as straightforward. ;)
So, what is your problem? Can't connect to the VNC server? What kind of
container did you tried? Does it have a separate IP address assigned?
The IP should be from that container. The display number is usually 0.
So, you should specify
QEMU_OPT += 127.0.0.1:0
if your IP is the same as a host machine (you can try a simple chroot
instead of a container, for simplicity. Then it's IP would be 127.0.0.1.
Also, in this case you will be able to access a local display, and VNC
will be unneeded)
So, the problem may be with accessibility of your VNC display from
outside the container. But you could try chroot for simplicity, as I
suggested. VM is a worst option, because you'll need to run QEMU inside
this VM for testing the binaries, which will be slow.
Anyway, thank you very much for your assistance.
Yours sincerely,
Subhadeep

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'

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!

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.
