Hi, Thanks you very much for that. I now have it running. I have another question about Genode. More specifically, I was wondering whether any of the Iguana services at all. I ask this given that the weaver.xml file refers to memsections and pds (i'm assuming that means protection domains). Peter ----- Forwarded message from Norman Feske <norman.feske@...1...> ----- Date: Tue, 05 Jan 2010 08:43:36 +0100 From: Norman Feske <norman.feske@...1...> Reply-To: Genode OS Framework Mailing List <genode-main(a)lists.sourceforge.net> Subject: Re: Broken assertion To: Genode OS Framework Mailing List <genode-main(a)lists.sourceforge.net> Hi Peter, this is a different error as the one mentioned in the Wiki. It actually tells you what's wrong. ;-) In the 'weaver.xml' file, there is a memsection referring to a file called 'config'. This is the configuration file of Genode's init process. You can use a copy of the template provided at 'os/config/demo'. You can either specify this file as filename for the 'config' module entry in 'weaver.xml' or copy it to your '<builddir>/bin/' directory (and of course rename it to 'config'). This bit was missing in the Wiki. So I added it to the Wiki page. Thank you for pointing it out.

Interaction with L4
by Peter Nguyen 31 Jan '10

31 Jan '10

Hi, I'm trying to port some code that I originally implemented in Iguana. This functionality pertains to profiling functionality. In my current setup (ie. with Iguana), I added an L4 system call (OKL4) to start and stop profiling. I'm wondering whether it's possible at all to use OKL4 functionality directly in writing genode apps. The profiling code that I have implemented is L4 code, where some of the code uses OKL4 IPC primitives and a small amount of Iguana based code with regards to creating threads. Any help on this would be greatly appreciated. Thanks Peter N

additional question from "memcpy, strlen etc."
by Peter Nguyen 29 Jan '10

29 Jan '10

As an addition to the previous post by me, I have some pre-existing C code that I want to use in a Genode server I have created, and I don't really want to change this code. Currently, i'm not able to utilize functions like printf, memcpy etc in the C code i've written. What header files can I include to ensure that functions like memcpy and printf work in my code? From what I can see, the build process does not recognize the standard header files at all. Peter

Hi, In doing some more investigating, for some reason, that message seems to pop up when i instantiate a thread. Before this thread, i instantiate 3 threads, which execute fine, yet when i instantiate this 4th thread, it doesn't work. Furthermore, when i only instantiate this 4th thread (ie. commenting out the 3 previous thread instantiations), this thread works fine. Peter

Hi, I am trying to get qt4 on genode 9.11 to work. I am using pistachio. When I try to run a iso using qemu, it halt and give a pagefault on CPU 0. Does anyone have a grub menu list file and genode config file for a qt4 demo? I have no problem running simple genode application on pistachio such as scout. Thanks, Shuo

Thread IDs
by Peter Nguyen 20 Jan '10

20 Jan '10

Hi, So I've done some more messing around with genode (running on top of OKL4), more specifically creating some threads, and testing the functionality in general. I'm wondering how i can go about obtaining the thread's ID and printing it out. I've noticed that there are functions that are within the Thread class that can get me a Native_thread_id, but currently I can't seem to do much with it. Speaking of the native thread, is that type related to L4? Can I actually get a numerical value for that ID? Peter

Build errors
by Peter Nguyen 18 Jan '10

18 Jan '10

Hi, In running genode with the "hello" app, I keep getting the following message: [init] starting hello_server with quota=262144 [init] using unique child name "hello_server" [init] Warning: Could not open file "hello_server" at ROM service. I also get the same thing with the hello client. Does this mean that the hello app is not loading at all? What do I need to do to fix this? Thanks Peter N

Broken assertion
by Peter Nguyen 05 Jan '10

05 Jan '10

Hi, In the wiki describing how to build Genode on OKL4, does the bug alert refer to following message: An error occurred: [Errno 2] No such file or directory: 'config'? I've followed the build instructions, and i've changed the value as suggested as the quick fix, but I still get this error. As usual, any help would be greatly appreciated. Peter

Hi, I'm trying to boot genode on OKL4 natively. I followed the instructions for building genode via the following link: http://genode.org/community/wiki/revisions/GenodeOnOKL4.6/?searchterm=build I've tried building version 9.05, but when i try to boot it up, i keep getting a grub error (Error 28: Selected item cannot fit into memory). Does anyone have any ideas why this is occurring? Peter N
