We are currently changing our build environment and unfortunatly the l4 libraries on our ftp server are some older versions. There are some Makefiles missing. We have to fix this. In the meantime you can either fetch a current copy of l4sys and l4util using cvs or install some missing links by yourself. Simply create include/l4/{sys,util} in your l4 directory and link all header files from the pkg/l4{sys,util}/include/l4/ to it. I will ask Michael to provide a new snapshot for the l4 libraries.

Error while Compiling L4Linux
by Christian Ceelen 30 Jun '99

30 Jun '99

Hi, I downloaded the L4Linux (and all other Components) through the CVS, configured it and tried to compile it. I received a lot of error messages and the compiler stoped without building the kernel (tried it with 2.0 and 2.2). What's wrong or where can I find a working version? Thanks, Christian Ceelen eMail: Christian.Ceelen(a)ira.uka.de error log /home/l4/l4/linux22 $make all (...) /home/l4/l4/linux22/include/asm/processor.h:19: l4/sys/types.h: No such file or directory In file included from /home/l4/l4/linux22/include/linux/unistd.h:9, from init/main.c:16: /home/l4/l4/linux22/include/asm/unistd.h:29: l4/sys/kdebug.h: No such file or directory /home/l4/l4/linux22/include/asm/processor.h:223: parse error before 4_threadid_t' +many more in processors.h Here is now the exit: /home/l4/l4/linux22/include/linux/sched.h:303: field ss' has incomplete type make: *** [init/main.o] Error 1 /home/l4/l4/linux22 $

Re: netboot support for GRUB

There is no GNU > GRUB webpage yet, so I attach the draft below. What's the difference between GNU GRUB and Erich Boleyn's original GRUB? (Your draft webpage doesn't say this, but it should.) Does Erich still maintain GRUB? There is a potential licensing problem because parts of the netboot code we've started from are licensed under a BSD license while GRUB is GPL'd, so it may be illegal to aggregate the two. So far, we've chosen to ignore this problem. What's your stance on this? Michael -- hohmuth(a)innocent.com, hohmuth(a)sax.de http://www.sax.de/~hohmuth/

Re: latest cvs & previous snapshot are compatible ?

However, we don't do a lot of integrative testing with what we check into our CVS repository; so what you get from the CVS can be less stable than what you find in the snapshots, although we do aim to having a working state at all times. > I've just compiled new Fiasco (main, rmgr, sigma0), > sample server (hello) and L4-Linux 2.2 on my PC. > I copied them into the grub-ext2-fs-floppy > (thus, grub is same with that of the previous snapshot), > but I could not make them work well, even hello server > does not run.

netboot support for GRUB
by OKUJI Yoshinori 12 Jun '99

12 Jun '99

Hello, I was asked why we hadn't integrated the netboot support in the DROPS version of GRUB into GNU GRUB. That is just because we don't have the time. If the developers can adapt the code to GNU GRUB, I would be glad to merge the change with GNU GRUB. There is no GNU GRUB webpage yet, so I attach the draft below.

latest cvs & previous snapshot are compatible ?
by suzukis＠file.phys.tohoku.ac.jp 11 Jun '99

11 Jun '99

Hello, The latest Fiasco which is available through CVS has the compatiblity with the previous snapshot (at 990428)? I've just compiled new Fiasco (main, rmgr, sigma0), sample server (hello) and L4-Linux 2.2 on my PC. I copied them into the grub-ext2-fs-floppy (thus, grub is same with that of the previous snapshot), but I could not make them work well, even hello server does not run. (Sorry, I can't report displayed message at present.) I will check some couples of the combinations among old/new kernel, old/new pager, old/new server, etc. If compiled correctly, the new programs can cooporate with old programs? suzuki

There are currently two L4Linux architectures, one for x86 and the other one for MIPS (MIPS is still under development). Simply change ARCH to l4-i386 to build L4Linux for x86.

L4Linux 2.2; Remote CVS
by Michael Hohmuth 10 Jun '99

10 Jun '99

Hackers, we've released a port of the Linux kernel version 2.2 (available via remote CVS -- see below). It runs quite stably on L4/x86, but we have to conduct some more tests with Fiasco; that's why, we haven't released a snapshot yet. Also, we have set up read-only access to parts of our CVS repository: you can now access via CVS the latest (unstable) code of L4Linux 2.0, L4Linux 2.2, Fiasco, Rmgr (and other components of the L4 development environment), and our versions of the OSKit and GRUB. For access information, please visit <URL:http://os.inf.tu-dresden.de/drops/download.html>. Michael -- hohmuth(a)innocent.com, hohmuth(a)inf.tu-dresden.de http://home.pages.de/~hohmuth/

But we do want to support it, and we're willing to work with anyone planning to get Fiasco going on it. Cheers, Michael -- hohmuth(a)innocent.com, hohmuth(a)sax.de http://www.sax.de/~hohmuth/

SMP-Fiasco,Compare it with QNX
by Gottfried F. Zojer 09 Jun '99

09 Jun '99

Hello, I m a newbie to this list and also in case of Kernel-programming. So I writing this mail with the hope that any feedback is coming. First I was a OS/2 Programmer also using the Watcom-Compiler.For the reason that the support of IBM was uncalculatable I tried to find something different there I can use my Watcom skills.And I found QNX.But it was simple to expensive for my use but I was thrilled from it s abilities.So I will ask some question to the list in the hope of feedback. 1)Tried somebody to compile FIASCO with a different compiler then GNU GCC 2)Are there any plans to support SMP or other forms to use this kernel in High Performance Computing or Clustering. 3)From QNX I own the Demodisk(IAT-Internet Appliances Toolkit).Exist something similar for FIASCO and DROPS. 4)Tried somebody FIASCO kernel on Embedded products from AMD and Jumptec. Nice greetings from Austria Gottfried F. Zojer
