Hi the linux kernel is 2.6.15-1.2054-FC5, gcc is 4.1.0 20060304. code is the latest update. following is screen copy of gdb Fiasco-UX on Linux 2.6.15-1.2054_FC5 (i686) Mapped 64 MB Memory + 0 KB Framebuffer + 0 MB Input Area on FD 6 Loading Module 0x00090000-0x00099380 [sigma0] Loading Module 0x00120000-0x002b09e4 [roottask] Bootstrapping...

Hi all, I am having problems trying to build the L4Linux kernel, has anyone seen the problem shown? -bash-2.05b# pwd /fiasco_part/src/l4linux-2.6 -bash-2.05b# make CHK include/linux/version.h CHK include/linux/utsrelease.h CHK include/linux/compile.h dnsdomainname: Host name lookup failure GEN .version CHK include/linux/compile.h dnsdomainname: Host name lookup failure UPD include/linux/compile.h CC init/version.o LD init/built-in.o LD .tmp_vmlinux1 ld: cannot find -lrtc make: *** [.tmp_vmlinux1] Error 1 -bash-2.05b# I have tried to search for an error, but to be honest , I'm lost... Please help? Thanks, Dave

Did anybody try this? Something like this is in 2.4. I do not think this is particularly hard. The concepts are the same. One needs to get some memory from somewhere, start tasks somewhere, etc. I don't see big obstacles. > >> e) If Fiasco would be running on PowerPC, would it be possible > >> to run L4Linux without changes? > > If one wants to have binary compatibility then some PPC code needs > > to be there.

Is that still the case? I'd rather they that it's adapted to run in user-level, using L4. Some of the instructions cannot be executes on user-level, they're replaced, or removed, or whatever. > And so far only the IA32 part of Linux is changed that way, isn't it?

Basically yes but all the architecture independant code is already there, and two example architectures. Adam

missing l4exec
by halo.duan 15 Dec '06

15 Dec '06

Hi all I check out latest fiasco and l4linux-2.6-env and built it successful. but I find l4exec bin no where. I read Makefile of the l4/pkg/exec directory find it get no l4exec target(include instead) , so i change the target to l4exec. It's failed to build. so what happened. It need not l4exec any more or something error in my build environment or binutil. my system is linux-2.6.15 and gcc version is 4.0.1 best regards.

Wiki for updates
by Shakthi Kannan 14 Dec '06

14 Dec '06

Hi, I was wondering if it is possible to install any wiki for l4 hackers to update the documentation. Most of the documentation is outdated or it doesn't work with currenct CVS code - hiworld example, for instance: http://os.inf.tu-dresden.de/l4env/doc/html/bid-tut/node3.html Build steps also seem to be different for some of the documentation. Maybe those who are testing CVS code can update the wiki? Any thoughts?

L4Linux on L4Ka::Pistachio
by Christian, Martin, OPEE45 14 Dec '06

14 Dec '06

Hi! 1. Status Report ================ I've got a L4Ka::Pistachio running on an embedded PowerPC and my goal is to get a Linux running on top by end of January. This is part of my "Diplomarbeit" at the University of Leipzig. 2. Questions ============ a) Is the L4Env required for running L4Linux? b) How much time would it take to port L4Env to L4Ka::Pistachio? c) If L4Env was ported to L4Ka::Pistachio, could I run L4Linux without changes? d) What about the Fiasco port to PowerPC from Mathias Lange? He mentioned some problems, so it didn't work. Is it running now? Where could I get the source code? e) If Fiasco would be running on PowerPC, would it be possible to run L4Linux without changes? f) I've read something about L4Linux running on L4Ka::Pistachio with Kernel 2.4? Did I get that right? So I could at least get an old Linux kernel running on my system. g) Anything else? Best regards and thanks for your time, Martin.

Building Fiasco-UX
by Shakthi Kannan 11 Dec '06

Hi, I am trying to build Fiasco-UX as per the documentation: http://os.inf.tu-dresden.de/fiasco/ux/building.shtml on Ubuntu Dapper (Intel, x86). gcc is 4.0.3. g++ is 4.0.3. I have obtained the code from CVS. Did menuconfig: cd l4/kernel/fiasco make menuconfig Have enabled: * Target platform (choose UX) * Generate inline code I don't see the "Assembler IPC shortcut" option. Saved the config. On running: make I get the following errors: make[1]: Circular l4/kernel/fiasco/src/Modules.ux.o <- Modules.ux dependency dropped. make[1]: Circular .Modules.deps <- Modules.ux dependency dropped. make[1]: Circular l4/kernel/fiasco/src/rules.cml.o <- Modules.ux dependency dropped. make[1]: Circular l4/kernel/fiasco/src/rules.cml.o <- .Modules.deps dependency dropped. make[1]: Circular create-sources <- Modules.ux dependency dropped. make[1]: Circular create-sources <- globalconfig.out dependency dropped. make[1]: Circular create-sources <- .Modules.deps dependency dropped. l4/kernel/fiasco/src/Makefile.sub1:17: .Modules.deps: No such file or directory make[2]: *** No rule to make target `.Modules.deps'. Stop. make[1]: *** [create-sources] Error 2 make: *** [build] Error 2 Appreciate any help in building fiasco-ux. Thanks, SK -- Shakthi Kannan http://www.shakthimaan.com ____________________________________________________________________________________ Cheap talk? Check out Yahoo!

Yes, I know it's quite old, whereas I don't know whether there is another more useful one. Thanks for your reply!
