Patch series available in this git branch: https://xenbits.xen.org/git-http/people/aperard/xen-unstable.git br.build-system-xen-v9 v9: One new patch (patch 3). Otherwise, detailed change logs in patches. Removed the rfc part about doing out-of-tree build without setting VPATH (which would have allowed mixed in-tree / out-of-tree builds). v8: Mostly rework of v7. With many patch already applied. Some detail changes that are spread through many patches: - `make cloc` recipe should now work throughout the series, update of it is done in 3 patches. - new patch "build: fix enforce unique symbols for recent clang version" to fix an issue with clang. - introducing $(srctree) and $(objtree) earlier - introducing $(srcdir) as shortcut for $(srctree)/$(src) - introduce usage of -iquote instead of -I in some cases More detail change log can be found in patches notes. Also this v8 present a work-in-progress of the ability to do out-of-tree build without setting VPATH. This is presented as an alternative to force use of out-of-tree build. As the last patch show, it allows to build the xen-shim without the linkfarm and we don't need to make any other changes to any thing that build xen (osstest, distribution packages, xen.git, ..., and developers finger macros). The patches are only there as WIP / RFC as they were some concern about the usefulness and extra changes needed. We can decide whether those changes are good or if this is too much and we should force out-of-tree build for the hypervisor. v7: Out-of-tree build! This mean many more patches. Everything after patch 27 is new. There's a few new patch before that, but otherwise are rework of v6. Hi, I have work toward building Xen (the hypervisor) with Linux's build system, Kbuild. The main reason for that is to be able to have out-of-tree build. It's annoying when a build fail because of the pvshim. Other benefit is a much faster rebuild, and `make clean` doesn't take ages, and better dependencies to figure out what needs to be rebuild.
