RE: compilation error for l4linux 2.6

That sounds promising Adam. But I am having this trouble with compiling L4Env. I downloaded all the stuff, and tried to compile the L4Env. But L4Env needs linux22 (I have no clue why?) I have that in ../l4linux22 directory, but inside a makefile in l4linux22/arch/l4/ there is a hard coded requirement for GCC to be 2.95 and my compilation stops at that point. I have GCC 3.3 something. Can someone tell me what should be done in this case? Thanks.

You are probably missing libloader.s.so in your build tree. This library comes from l4/pkg/loader/lib/runtime and should install to l4/lib/*/*/libloader.s.so. You also need to enable the option to build libloader.s.so in the configuration menu.

RE: L4Linux bootprompt question

Thanks a lot. That helped a lot. F Everyone's I, More information on major and minor devices can be found at src/Documentation/devices.txt I had a boot CD for l4linux on fiasco. It was loading a ramdisk which was getting the binaries from CD. Since I was having no luck getting l4linux compiled, I decided to copy these binaries to hard disk and change the grub.conf to make it boot from hard disk. But after doing some intuitive things I found that it won't load l4linux until CD is put in. So I tried to learn how the bootloading takes place. In the process I stumbled upon this root=1:0 problem mentioned up in the thread. My ext3 root file system is installed on /dev/hda6, from the devices.txt file mentioned above I got that 1:0 stands for RAMdisk and for /dev/hda6 I will have to put 3:6. It worked (with the help of RAMdisk provided on l4linux download page).. However now I have come to know that there is no passing around compilation of L4Linux and L4Env, because the ram disk is designed for 2.6.8.1 and it looks for /lib/2.6.8.1... which I will need to build myself. Anyway. Thanks.

L4Linux bootprompt question
by Jayesh Salvi 09 Feb '05

09 Feb '05

Hi, I an confused about the bootprompt arguments mention in the l4linux.cd.k_us.cfg file that is given to the loader to load the L4Linux 2.6 kernel. The line is : task "vmlinuz26" "mem=44M noreplacement root=1:0 load_ramdisk=1 ramdisk_size=4096 l4env_rd=initrd.gz panicblink=0 lang=us" What does root=1:0 mean? After referring to "The Linux Bootprompt - HowTo" http://ldp.rtin.bz/HOWTO/BootPrompt-HOWTO-3.html#ss3.1 I figured out that the argument is of the type root=/dev/* Can anyone help me understand what "root=1:0" mean? This boot loading files are from the Fiasco-L4Linux boot cd available at http://os.inf.tu-dresden.de/L4/LinuxOnL4/demo.shtml Thanks. Jayesh
