Hi, I am new to Genode and love it (particularly the release notes!).
I am having a problem linking fb_sdl with while compiling Genode 12.11
on LuninuxOS (based on Ubuntu Quantal) 64 bits:
paul@paul-P5GZ-MX:~/Bureau/Genode/genode-12.11/build.lx$ make
run/demousing run script
/home/paul/Bureau/Geno
Just found the libs on my system, but I don't know what to do next:
paul@paul-P5GZ-MX:/usr/lib/x86_64-linux-gnu$ locate libpulse
/usr/lib/libpulsecore-2.1.so
/usr/lib/vlc/plugins/access/libpulsesrc_plugin.so
/usr/lib/vlc/plugins/audio_output/libpulse_plugin.so
/usr/lib/vlc/plugins/services_discove
Problem solved by:
paul@paul-P5GZ-MX:/usr/lib/x86_64-linux-gnu$ sudo cp
pulseaudio/libpulsecommon-2.1.so .
[sudo] password for paul:
paul@paul-P5GZ-MX:/usr/lib/x86_64-linux-gnu$ ls libpuls*

First, I did not search yet for issues showing this.
It is just a ... "hey, that's seems wrong, anyone knows about this?".
After my "make run/demo" on Linux Ubuntu 64 bits, I got a big black
window, that was empty so I closed it.
The log after compilation shows:

Just in case someone else is asking himself/herself the same question

Yep, manually applying the patch make the launchpad window to work.
Thanks!
That said, I was using the Genode toolchain which is gcc 4.7.2 from:

I was merely following instructions in getting_started.txt that is not

Just giving a small glitch while trying run/demo on Nova (x86_64).
First I am using a 2 day old master.zip file of Genode (because I had

However I have a new git clone of Nova that did work fine.

Ok, so I burn my var/run/demo.iso file from my build directory (8 MB,
impressively small!) to a CD and tried it.

Hi!
This 0-1000 address you are trying to give VESA... this is virtual memory?
I was asking because when I did read that one of the goal about 2013.2

* IOMMU support on NOVA
I remember to have read that IOMMU is often found on motherboard
having PCI express.
This one is AGP I think.
Ah no, I think I can guess (all my understanding is rather fuzzy).
This 0-1000 thing, is my old real mode interrupt table (256 entries,
of 4 bytes each).
Well, I am surprised to see how this x86emu can be coded in user mode.
But I find strange that so much assembler seems to need to be
emulated, I
My current guess is that you don't use virtual 8086 mode but rather,
emulate it in protected mode (as user code) mostly to call (euh run,
much as an assembler interpreter) Vesa BIOS int 0x10 to set video mode

About a GUI for Genode.
That's in the roadmap for the beginning of 2013.
So I began to think about it.
My first idea was an old idea, very simple.
Each visual application (text or graphics) had it's own framebuffer
(could be different size for each).
When pressing Ctrl-PageUp or Ctrl-PageDown, you
Rather than having the notification area to the right, I want it at the bottom.
It should contains 2 or 3 lines of text with the following fields:

area to that application.

Now, I was beginning to think of a general form application.
Many application need forms to be filled, and a general application
for that seems to make sense.
When a button is click, or a text area is changed, the general
application could signal it to the application 'model'.
Anyway, that is not
Well, about the GUI, once again.
I had: +:New -:Delete Up:Next Down:Previous.
I should add a toggle button: 1/List: toggle the 'application' area
between the selected one, and the list of things.
Now, especially for programs, the list of things is not clear because
there is in fact two lists:
1)
Scrap almost all.
Let's have 4 levels:
Tasks -> Categories of applications -> Applications -> Instances of an
application
There is always just one band shown on the left, showing these buttons:
Esc) Go to the higher level
Up/Down) Navigate between items

Ok) Level depe
It looks like Qt is the currently (prefered) GUI library for Genode.
I am trying to push it toward EFL with this message. ;-)
Ok, frankly, I did not begin to develop any application either with Qt or EFL.
I am still kind of searching which GUI libs I should learn.
Anyway, what is Enlightenment?

About the GUI once again.
