FW: error in writing code for IPC servers & problem with Fiasco-UX
by Lucyantie Mazalan 29 Jan '08

29 Jan '08

Hi, Thanks for the reply. With this email I hope to resolve my previous problems and also seek for solution of new problem. First, to respond you from previous email: | * your package dir is called aes, so all include files need to be | included through something like <l4/aes/...> Yes, previously my package name was that but I rename the archive file name to aes for your reference. But, however I am now sending to you the fixed one which all the include path is exactly same as the package name, aes. Sorry for that. | * the IDL file somehow needs to know about your aes_context type, so | either include it from a header or define it inside the IDL file - I did | so by uncommenting your stuff. Thank you, yes I have fixed it by defining the aes_context type inside the IDL file. I have also recompiled it; generate new server code and writing new same implementation in my server's functions. | And this was probably your problem: | - ---> | * The aes-client.h file should be included using | ~ #include "aes-client.h" | ~ without any directory prefixes. It is a generated header file which | ~ does not end up in the L4 include dir, but resides inside the | ~ package's IDL build dir. This is path is different from the usual | ~ include paths and is added to your compile run automatically by BID. Thank you for the information. Yes I have also fixed in my aes package file which includes the header with just a '#include "aes-client.h"', without the prefixes. However, when I compile again my client code, I still got the same error which makes me more confused of where is actually the problem is. Here I attach the pkg archive and paste the errors that I get: ---------------------------------------------------------------------------- root@lucy-ubuntu:/# cd home/fiasco/l4/pkg/aes/examples/client/ root@lucy-ubuntu:/home/fiasco/l4/pkg/aes/examples/client# make O=/home/fiasco/build/ PWD=/home/fiasco/build/pkg/aes/examples/client/OBJ-x86_586-l4v2 make -C /home/fiasco/build/pkg/aes/examples/client/OBJ-x86_586-l4v2 -f Makefile make[1]: Entering directory `/home/fiasco/build/pkg/aes/examples/client/OBJ-x86_586-l4v2' ...

Question about semaphores and threads
by Marc CHALAND 28 Jan '08

28 Jan '08

Hi, Sometimes, I get the following message : semaphore/lib/src/semaphore.c:167:__enqueue_thread(): Error : l4semahore: failed to get priority of thread 17.08: invalid argument (-3) Into sources, the comment says that thread has not been created by l4thread or is dead. But all threads are created by l4thread and no one is explicitly killed by another thread. Is there a mechanism which kills threads ? Is it possible a lock is requested as thread is not completely created ? Anybody has got an idea on what happens ? Regards Marc

What's wrong with my l4con
by fei li 28 Jan '08

28 Jan '08

These days I have tested l4con on my machine. First I just move the l4con package into my L4Linux directory and modify my menu.lst, but I can't get the result. Then I copy the menu.lst from the wiki, and it's ok. Now I have several questions and hope someone helps me. This is my own menu.lst title L4Linux26/Fiasco+dope #root (hd0,7) kernel /boot/L4Linux/bootstrap modaddr 0x06000000 #module /boot/L4Linux/main -nowait -nokdb module /boot/L4Linux/fiasco -nokdb -serial_esc module /boot/L4Linux/sigma0 module /boot/L4Linux/roottask task modname "bmodfs" attached 7 modules module /boot/L4Linux/events module /boot/L4Linux/names --events module /boot/L4Linux/log --events module /boot/L4Linux/dde26_test module /boot/L4Linux/dm_phys --isa=0x00800000 -v --events module /boot/L4Linux/simple_ts -t 300 --events module /boot/L4Linux/rtc --events module /boot/L4Linux/l4io --noirq --events module #module /boot/L4Linux/omega0 --l4io #module /boot/L4Linux/l4dope #module /boot/L4Linux/proxygon module /boot/L4Linux/con module /boot/L4Linux/run module /boot/L4Linux/loader --fprov=BMODFS run linux26.cfg module /boot/L4Linux/bmodfs module /boot/L4Linux/vmlinuz module /boot/L4Linux/drops.rd module /boot/L4Linux/linux26.cfg module /boot/L4Linux/libloader.s.so module /boot/L4Linux/libld-l4.s.so vbeset 0x117 The next one is what I got from the web. title L4Linux26/Fiasco+dope kernel /boot/L4Linux/bootstrap modaddr 0x06000000 module /boot/L4Linux/fiasco -nokdb -serial_esc module /boot/L4Linux/sigma0 module /boot/L4Linux/roottask task modname "bmodfs" attached 6 modules module /boot/L4Linux/names module /boot/L4Linux/log module /boot/L4Linux/dm_phys --isa=0x00800000 module /boot/L4Linux/simple_ts -t 300 module /boot/L4Linux/rtc module /boot/L4Linux/l4io #module /boot/L4Linux/l4dope module /boot/L4Linux/con module /boot/L4Linux/bmodfs module /boot/L4Linux/linux26.cfg module /boot/L4Linux/libloader.s.so module /boot/L4Linux/libld-l4.s.so #module /boot/L4Linux/proxygon module /boot/L4Linux/run module /boot/L4Linux/vmlinuz module /boot/L4Linux/drops.rd module /boot/L4Linux/loader --fprov=BMODFS run linux26.cfg vbeset 0x117 Compare the two, first I find my own has a events module more and some options about events, then I add these to the one I got from the web, but it runs ok without any problem. Then I changed the last lines' sequence and my own menu.lst works. Maybe that's the problem, but I'm not very sure. Another thing puzzled me was that when I entered in the l4con and in the command line state, I wanted to quit from the l4con and input Q, then the messge is "input 'y' to quit", I input 'y', but it's not responding, when I input 'z', it says OK, what does this mean??
