fdisk image for pistachio

Aeeeee!

I jumped into the kernel debugger. Yes, my problem was about GRUB
settings, but the getting started with L4Ka::pistachio on ia32 document
has a little deprecated information. It's still quite good, but I think
so.


First, I hope to mention to download source from CVS repository. Of
course, I'm such a fool because I only tried to download tarball source.
Some newbies like me need more detail information.

Secondly, I post the following script to create floppy disk image which
sets GRUB settings correctly.

---------------------------
#!/bin/bash

rm -rf fdsource
mkdir fdsource
mkdir -p fdsource/boot/grub
cp /boot/grub/stage1 fdsource/boot/grub/
cp /boot/grub/stage2 fdsource/boot/grub/
cp ia32-kernel-build/ia32-kernel fdsource/
cp ia32-user-build/libexec/l4/* fdsource/

cat > fdsource/boot/grub/menu.lst << EOT

---------------------------


I tested in Ubuntu Dapper, gcc 4.0.3, GRUB 0.97.

As you know, I had to revise something provided in the Getting started
document. It could be very small, but I'm now happy to solve my problem
with GRUB manual. :)






Lastly, I had to modify the file, "pistachio/user/Mk/l4.lib.mk" as
follows :

-$(INSTALL) lib$(LIBRARY).a $(DESTDIR)$(libdir)/lib$(LIBRARY).a

I put '-' prior to $(INSTALL) to ignore error message. It says when
installing user-code :

/usr/bin/install: `libl4.a' and
`/home/cheeky/pistachio/ia32-user-build/../ia32-user-build/lib/l4/libl4.a' are the same file


Even though I fixed it, when installing user-code it gives a lot of
warning messages that they can't be copied. and Finally, it terminates.
Fortunately, I had no problem building user-applications themselves, and
obtaining the programs "ia32-user-build/libexec/*". Therefore, I could
see the boot-screen.


However, it's bothering to see lots of warning and/or error messages
when installing user-code applications. Thnak you.
