Hi Sebastian,
Thanks for the feedback.
Currently Genode outputs some error messages that might be misleading, but are necessary for us developers. "Quota exceeded!" is one of them. This means the configured component or program memory quota in Genode's 'config' file does not suffice, such a program will then ask its parent (in this case 'init') for more memory, which is successful in your case ('upgrading quota donation').
Ok, I didn't notice the "upgrading quota", that does make sense.
One can configure 'fb_sdl' via a ROM file and there are many ways to provide one. Nevertheless, this 'config' is not mandatory and 'fb_sdl' will also function without it. So, I can see no problems in the Log you provided. Therefore, I will attach a working output. Please let me know at what point your output differs. Also, what Linux version are you using in your VirtualBox setup? Information about the distribution, kernel version, and if it is 32 or 64 bit helps us a lot.
Also, I can't seem to find instructions for building an ISO. Is that possible?
Yes, add '--include image/iso' to the 'RUN_OPT' variable in <your-builddir>/etc/build.conf The ISO will in your case be located under <your-builddir>/var/run/demo.iso
I'm using ubuntu 15.10 (I didn't see the suggestion to use an LTS version in time). I'm using the 15-05 genode fundations pdf as a guide, particularly page 27. I probably need to read some more to get a better grasp of some concepts, but meanwhile please bear with me. I did:
./tool/ports/prepare_port nova && ./tool/ports/prepare_port x86emu ./tool/create_builddir nova_x86_64 && cd build/nova_x86_64 sed -r 's/^#(REPOSITORIES.*libports)/\1/g' -i etc/build.conf (cd ../../repos/libports && make prepare) # as suggested on etc/build.conf make run/demo
The iso file is created at this point, and I'm able to boot the VM with it and see the demo in action, but qemu refuses to run (please see the attached full output), because:
spawn qemu-system-x86_64 -no-kvm -cpu core2duo -m 256 -serial mon:stdio -cdrom var/run/demo.iso Could not initialize SDL(No available video device) - exiting
What is the "No available video device" about? I can do `startx` and get lxde running, so I don't think it's a virtualbox "hardware" issue. What step am I missing?
Qemu requires SDL for the display. Please add:
QEMU_OPT += -sdl
to your build.conf file that should fix the issue.
By the way, the `make prepare` for libports is only suggested in etc/build.conf; it might be helpful to include it on the instructions for the "simple system scenario" on the book.
Thanks for the suggestion,
Sebastian
