[Xen-devel] [Q]What are the build rules for Xen?
Hi All,
the standard linux kernel Kbuild system is good.
I have used it to add my new subsystem foo and build the modules by
editing/adding Kconfig files and Makefiles.
How do i add such a new directory in xen?
e.g I want to add a new directory say foo under blkfront for domU.
Can use the same rules as kbuild system?
Any caveats?
thanks

BTW there are no Kconfig or Makefiles in linux-2.6.-xen-sparse/net/core/* . If i add my foo/ directory under net, will xen build automatically recognize my Kconfig and makefile?[after i create them under sparse/net/foo/] and thus will it be included automatically during make world?

If this is just for local hacking you could modify the versions in the build tree without touching the sparse tree.

Linux kernel build was fine. I copied the tar.bz2 archive of this modified tree to xen-3.1 src directory and did a make world and now here is the problem. I get - "xen-3.1.0-src/linux-2.6.18-xen is not clean, please run ''make mrproper''." And i don''t want this. I want Xen to use the new tree. What am i supposed to do in Xen now? I am not an expert at xen build system so may be anybody good at it can give me some hints? Thanks in Advance --pradeep -- pradeep singh rautela "question = ( to ) ? be : ! be;" -- Wm.

You could take xenbits.xensource.com/linux-2.6.18-xen.hg and use that full Linux tree instead. We don''t use the Linux sparse tree in ongoing development any more. -- Keir On 11/9/07 06:41, "pradeep singh rautela" <rautelap@gmail.com> wrote:> Ok i added a new directory in standard Linux kernel, with correct > Kconfig and Makefiles altered/changed.

Re: [Xen-devel] [Q]What are the build rules for Xen?
Hi Keir, I have the latest linux-2.6.18-xen repos clone. xen-unstable repo is in the process of being cloned[ will take sometime it seems]. I have a very naive query now. - So a make world in xen-unstable now does not fetches a 2.6.18 bzipped kernel from kernel.org? - I guess now we need to copy the linux-2.6.18-xen src tree to xen-unstable and then do a make world??? or do make kernels? I hope answers to these are there in xen-unstables/README ? Thanks --pradeep On 9/11/07, pradeep singh rautela <rautelap@gmail.com> wrote:> Ok.

That is, you''ll have: /path/to/xen-unstable.hg /path/to/linux-2.6.18-xen.hg Make world in xen-unstable will then pick up the adjacent Linux repository. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
