Problems compiling kexec-tools

Problems compiling kexec-tools

All,

I'm attempting to compile kexec-tools so I can compile kboot from source.

 

I've obtained the kexec-tools-2.0.0 source from RPM.

 

I've done:

./configure

make

 

which I receive the following errors:

gcc -lz   -g -O2 -static -fno-strict-aliasing -Wall -Wstrict-prototypes -o build/sbin/kexec kexec/kexec.o kexec/ifdown.o kexec/kexec-elf.o kexec/kexec-elf-exec.o kexec/kexec-elf-core.o kexec/kexec-elf-rel.o kexec/kexec-elf-boot.o kexec/kexec-iomem.o kexec/firmware_memmap.o kexec/crashdump.o kexec/crashdump-xen.o kexec/phys_arch.o kexec/proc_iomem.o kexec/virt_to_phys.o kexec/add_segment.o kexec/add_buffer.o kexec/arch_reuse_initrd.o kexec/arch/i386/kexec-x86.o kexec/arch/i386/kexec-x86-common.o kexec/arch/i386/kexec-elf-x86.o kexec/arch/i386/kexec-elf-rel-x86.o kexec/arch/i386/kexec-bzImage.o kexec/arch/i386/kexec-multiboot-x86.o kexec/arch/i386/kexec-beoboot-x86.o kexec/arch/i386/kexec-nbi.o kexec/arch/i386/x86-linux-setup.o kexec/arch/i386/crashdump-x86.o kexec/purgatory.o libutil.a

I've installed zlib:

zlib-1.2.3-29.4.moblin2.i586.rpm

zlib-devel-1.2.3-29.4.moblin2.i586.rpm

so I'm unsure what I've done wrong.

 

Suggestions?

John

Just a guess, but do you have a static version of libz installed?
That is, did zlib-devel install a libz.a file?

Yes; libz.a is installed... but I may have installed 

zlib-static-1.2.3-29.4.moblin2.i586.rpm

being over zelous with the dependancy install.

 

I tried 

rpm -e zlib-static-1.2.3-29.4.moblin2.i586.rpm

as root but it says "not installed".

Maybe you could try just using the 2.0.1 sources from here:

You could try passing the verbose flags and see what
headers and libs get used during the build.  Maybe
you'll find some problem there.  I think those would
be something like:

  gcc -v -Wl,--verbose ...

Or maybe just use:

  ld --verbose ...

BTW, have you looked at the petitboot bootloader? For
the most part it is a better choice than kboot.
It provides essentially all the functionality that
kboot does, plus more, it is easier to build, and it
is a currently maintained project.

The petitboot package can be built for x86.  That is
how much of its development is done, but OpenWRT does
not yet support an x86 build of petitboot (that
would create a grub second stage image).  My plan is
to add x86 PC support next.  I don't think it is very
difficult to do, I just have not had time to do it.

You can see some screen shots of petitboot built for
the PS3 here:

  http://www.kernel.org/pub/linux/kernel/people/geoff/cell/ps3-petitboot/

My petitboot development repo is here:

  http://git.kernel.org/?p=linux/kernel/git/geoff/petitboot-dev.git

petitboot looks interesting; but I need the tool chain ready to go for x86.

Currently For our project, we are using a patched version of kboot which runs on x86.

 

I do see some benefit for petitboot with the graphical menu. Ideally we'd need a version which reads each partition looking for multiple /boot kernels and present a method to select each one using a alpha char. Kinda like the old System Commander app.

 

In my config; I'll have multiple linux kernels on the disk. I envision having Android, Moblin2.0, and several other flavors of linux in partitions and needing to boot to each at runtime.

Just FYI, petitboot is setup to receive hot plug events
(udev supported, hotplug-2 planned) and dhcp events.  It
looks on any storage devices for boot menu config files
and for any netboot info from dhcp and then adds or removes
boot menu items for those dynamically.

Petitboot does not look for kernel images it can boot,
as you need more than that to boot a kernel (initrd,
boot options, etc. are needed), nor does it test for
the existence of any images specified in boot config
files, as you would potentially need to be looking all
over the Internet for them, and waiting for network
timeouts, etc. just doesn't make sense.  Petitboot just
assumes the user keeps the configs in good order.

As for the 'one key' selection UI you mention, Petitboot is
setup with a client-server architecture.  The server deamon
is the thing that receives events, looks for config files,
parses the files, etc., then it sends the info to the client
UI apps.  Multilpe UI client apps can register with the
server, so you can say have one UI on the display, and
several running in telnet sessions.

Anyway, petitboot was designed for it to be relatively easy
to make a new custom UI app.  Your 'one key' selection
seems to be just a variation of the existing ncurses menu UI.

May I jump in and ask if you know about kexecboot?
http://projects.linuxtogo.org/mediawiki/index.php/Kexecboot

It's just kernel + minimal initramfs : kexec and kexecboot.

We would need more testing on other archs: we mostly build for arm
using OpenEmbedded.

Andrea
