hi,
i tried to build xcp dom0 kernel but no luck.
1. install kernel srpm
(kernel-2.6.27.42-0.1.1.xs0.1.1.737.1065.src.rpm from
http://www.xen.org/files/XenCloud/Software/latest/sources/source-1.iso)
2. run rpmbuild and got the following error.
# rpmbuild -ba --target i686 kernel-xen.spec
any idea? is there build instructions/scripts/etc somewhere?

What are the contents of /usr/src/redhat/{SOURCES,SPECS}?> any idea? is there build instructions/scripts/etc somewhere?I would have expected the steps you took to have worked. What is your build environment, just a regular CentOS 5.4 install or something else? Can you try: # rpmbuild --target i686 --rebuild kernel-2.6.27.42-0.1.1.xs0.1.1.737.1065.src.rpm I don''t really expect it will make any difference but that is precisely what the XCP build system does so it may be informative.

I''ll install up a VM and give it a go see if I can work out what is happening.> my build host is running CentOS 5.3 and its normal toolchain. > does ddk.iso contain some special toolchain which is different > from CentOS''s one?Nope, it''s just the standard one. There is a special 64 bit cross compiled (x86_64-linux-gcc) but that is only used for the hypervisor. Oh, I have an idea -- is you host running 32 or 64 bit CentOS?

XCP domain 0 is 32 bit and the kernel-xen.spec is obviously not quite right for cross compiling. I''d recommend installing a 32 bit CentOS VM and using that. You may be able to make cross compiling work for the kernel but if you get into building anything further down the userspace part you may run into even more troubles. If you want to try and get cross compilation working for the kernel only I think you would need to start by modifying the macro near the top of kernel-xen.spec file include a correct ARCH= in MAKEOPTS, probably by defining a kernelarch variable in the "%ifarch %{ix86}" and "%ifarch x86_64" blocks just above and using that.
