Help! Unable to build L4Env-0.2
by Wang, Chip 11 Jul '05

11 Jul '05

Hi fellow hackers, I am a newbie here. I am trying to build my first L4Linux-2.6 setup, but failed at building L4Env. I downloaded and unpacked the following S/W from the L4Env download page: - l4env-0.2 tarball - dde-0.2 tarball - libstdc++.0.2 - oskit-06302003 - oskit10-06302003 I also checked out L4Linux-2.6-env from CVS. I then followed the instructions and did 'make config' and 'make' from inside the 'l4' directory. The compilation eventually failed at building l4/pkg/loader. The linker complained that the library -lcon was missing. My Linux is 2.6.11 from Mandrake with KDE. My platform is an Acer TravelMate c300 notebook. I searched the mailing list archive but didn't see similar report of the problem I figure I must be missing some other pieces or having the wrong versions. By the way, I also got errors when building 'multiboot-smp'. I followed the suggestion to skip the example by creating a null executable. Should I do the same for this example? Could someone please show me what I did wrong? Thanks in advance for your help Chip The last portion of the build log is attached below. === Building servers, examples of "loader" === PWD=/home/drops/l4/pkg/loader make -C loader all -o lib -o include -o idl make[2]: Entering directory `/home/drops/l4/pkg/loader' test -f server/broken -o -f server/obsolete || \ if [ -f server/Makefile ] ; then PWD=/home/drops/l4/pkg/loader/server make -C server ; fi make[3]: Entering directory `/home/drops/l4/pkg/loader/server' test -f src/broken -o -f src/obsolete || \ if [ -f src/Makefile ] ; then PWD=/home/drops/l4/pkg/loader/server/src make -C src ; fi make[4]: Entering directory `/home/drops/l4/pkg/loader/server/src' PWD=/home/drops/l4/pkg/loader/server/src/OBJ-x86_586-l4v2 make -C OBJ-x86_586-l4v2 -f Makefile make[5]: Entering directory `/home/drops/l4/pkg/loader/server/src/OBJ-x86_586-l4v2' ==> Linking loader LD_PRELOAD=/home/drops/l4/tool/gendep/libgendep.so GENDEP_TARGET=loader GENDEP_BINARY=ld gcc -o loader ../../../../../lib/x86_586/crt0.o trampoline.s.o main.o cfg-parse.o cfg.o pager.o app.o fprov-if.o dm-if.o exec-if.o idl.o events.o lib.o loader-server.o -Ttext=0x01300000 -L../../../../../lib/x86_586/l4v2 -L/home/drops/lib/x86_586/l4v2 -L../../../../../lib/x86_586 -L/home/drops/lib/x86_586 -L../../../../../lib -L/home/drops/lib -L../../../../../../oskit10/lib -L/home/drops/lib/oskit10 -T../../../../../lib/x86_586/main_stat.ld -ll4exec -lgeneric_ts -lgeneric_fprov -lloaderif -lcon -ldm_phys -levents -lparsecmdline -static -loskit10_support_l4env.o -lgeneric_ts -ll4env -ll4rm -ldm_generic -ldm_mem -lthread -lsemaphore -llogserver -lnames -ll4util -lrmgr -ll4env -ll4env_err -ll4rm -ldm_generic -ldm_mem -lthread -lslab -ll4sys -nostdlib -Wl,--nostdlib -ll4env -ll4rm -ldm_generic -ldm_mem -lthread -loskit_c -loskit_kern -loskit_clientos -loskit_lmm -loskit_kern -loskit_c /usr/lib/gcc/i586-mandrake-linux-gnu/3.4.3/libgcc.a -loskit_c -Ttext=0x01300000 -Wl,-gc-sections /usr/bin/ld: cannot find -lcon collect2: ld returned 1 exit status make[5]: *** [loader] Error 1 make[5]: Leaving directory `/home/drops/l4/pkg/loader/server/src/OBJ-x86_586-l4v2' make[4]: *** [OBJ-x86_586-l4v2] Error 2 make[4]: Leaving directory `/home/drops/l4/pkg/loader/server/src' make[3]: *** [src] Error 2 make[3]: Leaving directory `/home/drops/l4/pkg/loader/server' make[2]: *** [server] Error 2 make[2]: Leaving directory `/home/drops/l4/pkg/loader' make[1]: *** [loader.bin] Error 2 make[1]: Leaving directory `/home/drops/l4/pkg' make: *** [pkg] Error 2 The information contained in this e-mail message is PRIVATE.

Has anyone an idea where to tweak this? As a general remark: Hardcoded paths in the build process should be avoided. Best example #!/bin/bash in scripts which should be replaced by #!/usr/bin/env bash or even better #!/bin/sh for better portability. I think the whole build process needs some kind of autoconf magic, too, to make it less GNU/Linux dependent.

using l4linux structures in l4
by Andrew Davenport 11 Jul '05

Hello, What is the simplest way to use (eg) the task_struct from linux inside the l4 microkernel. I want to use exactly the same declaration in the kernel, but I am having difficulty using it. Thanks, Andrew

exception -> l4_ipc ?
by Andrew Davenport 11 Jul '05

11 Jul '05

hi, i see thread::raise_exception(ts), and i know this is where l4 notices a linux sys call (int 0x80), however, i do *not* see where the ipc is sent to the linux server to tell it that a syscall has occured (and to get the parameters and handle it)... thanks in advance, -andrew

Some questions
by fabs0028＠free.fr 07 Jul '05

07 Jul '05

Hello, I first wanted to signal about a little problem i found : when i launch an application i did for l4 with the loader it works fine but after its end i want to launch a legacy linux application and i get the message KERNEL: Security violation: Not pager of 36. Maybe i forgot something to close my program but i don't know what or maybe it is something else. I also wondered if it was possible to build a standard linux kernel from the l4linux sources ? I think so but i'm not sure. And for a last question i'd like to know if there's a way to share devices such as for example hard drives between l4 and the l4linux server. I saw dde but i don't know if it is still up with the 2.6 portage and i haven't found a lot of doc about it except the manual. Thanx a lot for your help. Fabien Chaillou

using patched gcc toolchain
by Emanuel Thomas 07 Jul '05

07 Jul '05

Hello, I want to use a patched gcc toolchain, but i'm going to have problems. Is there a global configuration file where I can (easily) which gcc (and other tools) should be used? Even "make confg" seems to use the standard gcc. Where can I change that? Emanuel

All, With this setup, what's the best way to reboot the system remotely (e.g. via ssh)? Rebooting the L4Linux server appears to exit all linux related activities and terminate their L4 tasks but the system does not reboot. Thanks! -Julian > Hi, > > I got it working.
