While I Compile the L4 system libraries and support servers, I receive in output this error message: /usr/lib/gcc/i486-linux-gnu/4.1.2/libsupc++.a(cp-demangle.o): In function `d_demangle': (.text+0x3fb7): undefined reference to `__stack_chk_fail_local' make[5]: *** [ipcmon] Error 1 make[4]: *** [/home/david/tudos/l4/microkerne1/pkg/ipcmon/server/src/OBJ-x86_686-l4v2] Error 2 make[3]: *** [src] Error 2 make[2]: *** [server] Error 2 make[1]: *** [ipcmon.bin] Error 2 make: *** [pkg] Error 2 What's the problem?

Re: roottask boot panic
by huang 12 Sep '07

12 Sep '07

hi,dear Adam: thanks a lot for your time and effort! You are right! But is there any difference if I build the binaries in one run or not? I still have another problem that may have the same reason as this one: If I unpack the fiasco kernel first and build it, I can run the hello(many_thread,many_tasks...) example successfully. But when I unpack the l4env and build again, the hello package can not pass the compilation processs. I can not find the reason. can you give me some advice? best wishes! >From: Adam Lackorzynski <adam(a)os.inf.tu-dresden.de> >To: l4-hackers(a)os.inf.tu-dresden.de >Subject: Re: roottask boot panic >Date: Thu6 Sep 2007 10:01:42 +0200 > > >On Wed Sep 05, 2007 at 09:47:29 +0800, huang wrote: >> I met the problem of roottask boot panic, do you know what's the reason? >> The output is: >> >> Roottask. >> Roottask boot panic: invalid KIP magic 00000001 >> [Esc] reboot, [k] kdebug, [M] memory map, [r] region map >> >> and my menu.lst is: >> title hello world >> kernel (hd0,0)/fiasco/bootstrap >> modaddr 0x02000000 >> module (hd0,0)/fiasco/fiasco -nokdb -nowait >> module (hd0,0)/fiasco/sigma0 >> module (hd0,0)/fiasco/roottask >> module (hd0,0)/fiasco/log >> module (hd0,0)/fiasco/names >> module (hd0,0)/fiasco/dm_phys >> module (hd0,0)/fiasco/names_demo > >I just tried your binaries and I don't get your panic with Qemu.

TIMEOUT question
by huang 12 Sep '07

12 Sep '07

hi,dear all: I have a question about l4_ipc_sleep()! I want to make a stop between two ipc operation, so i used l4_ipc_sleep(), but it did not work! The code is : ... static void sleep(unsigned exp) { l4_ipc_sleep(l4_ipc_timeout(1,exp,1,exp)); } ... int main(int argc, char **argv) { ... for(;;) { ... sleep(4); } return 0; } I think sleep(4) should make a stop about 4 seconds, but the the call returned immediately. What's the problem in my code? thanks for your help! best wishes! 　　　　　　huang 　　　　　　　　learnl4(a)sina.com 　　　　　　　　　　2007-09-12

What is the difference between l4dm_mem_allocate, l4slab_alloc, malloc
by chenggh 12 Sep '07

12 Sep '07

Hi: In the l4vfs source code I am sure that the malloc function could be used in the L4 programming. But I also find two functions named l4dm_mem_allocate and l4slab_alloc. It seems that both of them could also allocate memory as malloc does. What is the difference between the 3 functions? Which one is fastest? Please help me. Thank you. Cheng Guanghui

L4linux is currently working with l4fb (Dope) or not?
by Tiago Lopes 07 Sep '07

07 Sep '07

Hello again, After spending a week trying all configs I could find, I'm (again) asking for help. I'm using an unmodified Opentc June snapshot and trying to get L4linux and dope working. Dope e running fine and L4linux is started, but it seems that L4linux cannot find the l4fb, and so the system boots and writes fine to the terminal, but not to dope screen... Is this config actually supported? Someone could give me a working config? This is my config files and output: Any help is much appreciated!

dear all: I met the problem of roottask boot panic, do you know what's the reason? The output is: Roottask. Roottask boot panic: invalid KIP magic 00000001 [Esc] reboot, [k] kdebug, [M] memory map, [r] region map and my menu.lst is: title hello world kernel (hd0,0)/fiasco/bootstrap modaddr 0x02000000 module (hd0,0)/fiasco/fiasco -nokdb -nowait module (hd0,0)/fiasco/sigma0 module (hd0,0)/fiasco/roottask module (hd0,0)/fiasco/log module (hd0,0)/fiasco/names module (hd0,0)/fiasco/dm_phys module (hd0,0)/fiasco/names_demo Best wishes! 　　　　　　　　huang 　　　　　　　　learnl4(a)sina.com 　　　　　　　　　　2007-09-05

Another solution is to update the find package. the find version more than 4.2.28 is ok. You could download the new find package from this link (http://ftp.gnu.org/pub/gnu/findutils/). Thanks.
