doxygen?!
by Flonai＠gmx.de 18 Apr '03

18 Apr '03

when i try to compile the the hello server by typing make hello in the l4 building dir, i got an error because i haven't installed doxygen. the problem is that i want to compile fiasco from an linux from scratch system and then using the l4linux microkernel. but doxygen needs xfree and some other progs and i do not want to compile it at this time course i am in an chroot environment with no other linux kernel. i heard doxygen is only need to build documantation files and i do not need them. so is there a way to change one/some makefiles to exclude doxygen. i used the cvs-reposetory (l4,oskit,and then linux22) modules from April 02. -- +++ GMX - Mail, Messaging & more http://www.gmx.net +++ Bitte lächeln!

on page 57. lipc conditions - use when it's clear that destination thread runs on the same CPU. does this mean scheduler will traverse the per CPU queue and look for idle destination thread?

You have to compile your own version of Hazelnut specifically for the iPaq. The Brutus board is not compatible (the memory layout is different). - Volkmar

L4 on iPAQ
by Dominik Gummel 02 Apr '03

02 Apr '03

Hello, I'm trying to install L4 on the iPAQ (3870). So far, my iPAQ has the "bootldr" bootloader and Linux installed. I tried to load the precompiled hazelnut rc2 evaluation suite for the brutus evaluation board over serial cable to ram (to address 0xC1000000) und jumped to this address (as Volkmar described in nov 2002 on this list). This didn't work. The iPAQ wrote some digits on the serial line and crashed. Has anyone who sucessfully installed L4 on the iPAQ some hints for me? Must I compile my own custom L4 for the iPAQ? Or must I use angelboot (I didn't find docs about it in google)? We need L4 on the iPAQ because we are going to port PERSEUS to it. My part will be the port of Linux 2.4 to L4/ARM (it will be my master thesis).

Hello! Thanks for the reply and sorry that I have to write from a different account but my link to the host in germany seems to be down since two days now. > On Wed Mar 26, 2003 at 07:38:33 +0100, Fabian Sturm wrote: > > > When I then boot into it I see some messages of the RMGR but > > then the system is frozen. > > > > Maybe someone knows what I should try next to track this down? > > Which version of GRUB are you using? Is it "our" version from CVS? Hmm I just took the newest from apha.gnu.org 0.93. I read that you have an own but I thought that is only needed if you have overlapping modules. > How did you configure Fiasco? Could you supply your configuration > (globalconfig.out)!? Sure. I followed the manual and did a make menuconfig in the build directory. I now also tried with the assertions compiled in but none gets triggered so far.
