Yes, this is ok. if yes, does it also mean the order of build l4env and fiasco is at our own choise? (build l4env first and then fiasco or build fiasco first then l4env) Yes, the order does not matter.

No, it's a default build. or i should set BUILDDIR to l4_all/kernel/fiasco/build? No. The way you build the kernel is fine. but the default build isn't base on my configuration (i enable 'Handle and preserve segments'). if i don't set BUILDDIR to l4_all/kernel/fiasco/build. how does default build know how i config fiasco? last time, you mentioned that : Yes, a default configuration is built into kernel/fiasco/build upon make in the l4 directory if not configured otherwise (see the L4 configuration menu). but i can't find any option in L4 configuration menu which is about fiasco? thanks for answering. when config l4linux: according to http://os.inf.tu-dresden.de/L4/LinuxOnL4/build-2.6.shtml, there are some options we shouldn't enable ex: like ACPI, SMP, preemption, apic/ioapic, HPET, highmem, MTRR, MCE, power management and similar. 1. does those options are default unable? or we should unable manually? 2. what does similar mean? With this statement I'm trying to express that for L4Linux one should _not_ enable any option that is close to the hardware, such as ACPI, HPET, MTRR etc. Remember, L4Linux is a normal user program and as such has no business doing anything with timer hardware or interrupt controller or similar. On the other side, you can enable e.g. any filesystem you like.

I run into problem compiling l4linux. I've been able to compile it many

I run into problem when building it. I'm pretty sure it will be some
stupid mistake I've made, but since I need to quickly finish some
testing, I would really appreciate any advise...
Here is configuration I use:
Debian {sarge, etch}; gcc version: 3.{3,4}, l4linux-2.6-17
Everything is mainly based on chenggh's kickstart and tarball he provided.
(http://os.inf.tu-dresden.de/pipermail/l4-hackers/2007/002732.html)
Could you also show the gcc call? (make V=1)
l4linux make log start
include/asm-l4/i386-arch/asm/alternative.h:7: error: syntax error before u8
include/asm-l4/i386-arch/asm/alternative.h:7: warning: no semicolon at end of
struct or union
include/asm-l4/i386-arch/asm/alternative.h:8: warning: type defaults to `int'
in declaration of `replacement'
include/asm-l4/i386-arch/asm/alternative.h:8: warning: data definition has no
type or storage class
I guess gcc doesn't like the u8 because it doesn't know what it means.
Does it help if you add '#include linux/types.h' in the beginning of
irq_multi.c? If it doesn't go away now, please also show your .config.
