* kbuild: use POSIX BRE in headers install targetMike Frysinger2007-07-171-7/+7
| | | | | | | | | | | | | | | The sed expression used at the moment in scripts/Makefile.headersinst relies on the (handy) GNU extension where you can escape ERE's in an otherwise BRE without using the GNU -r option. The following patch replaces this "\+" usage with a functionally equivalent POSIX BRE compliant "\{1,\}". Tested with `make headers_install` against blackfin/x86_64/i386 targets. Stupid whiny OS X users and their crappy sed ;) Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* x86_64: fix headers_installDavid Woodhouse2007-07-061-1/+1
| | | | | | | | | | | | | | | | | | A bug in headers_install for ARCH=x86_64 yields an asm/ directory full of files all of which are using the same #ifdef guard, "__ASM_STUB_" with no postfix. So the second and later asm files #included in the same C file (often through standard headers like ioctl.h) yields no symbols. Strangeness with the Ubuntu 'tell me if I support something that's not explcitly mentioned in POSIX, and I'll strip it out' shell, I believe. We don't need the 'export' but we do need a semicolon at the end of the FNAME line: Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Rob Landley <rob@landley.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* Make 'headerscheck' stop immediately on an errorDavid Woodhouse2007-05-211-1/+1
| | | | | | | | | | | | | | | | | | This should make it stop immediately after printing the _helpful_ error message, rather than continuing to spit out many pages more of 'CHECK include/linux/foo.h' before eventually coming to a halt with something less obvious. Now I get this...

| * Use dependencies for 'make headers_install'.David Woodhouse2006-09-241-45/+79
| | | | | | | | | | | | | | | | Re-export header files only if either they or their controlling Kbuild file has actually changed. Also allow for similar dependencies with 'headers_check', once we properly create the dependencies for those. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

* [PATCH] Fix 'make headers_check' on biarch architecturesDavid Woodhouse2006-09-161-3/+5
| | | | | | | | | | | | | | | | | We generate an <asm/foo.h> which includes either <asm-$ARCH/foo.h> or <asm-$ALTARCH/foo.h> as appropriate. But we were doing this dependent on whether the file in question existed in the _unexported_ tree, not the exported tree. So if a file was exported to userspace in one asm- directory but not the other, the generated file in asm/ was incorrect. This only changed the failure mode if it _was_ included from a nice #error to a less explicable #include failure -- but it also gave false errors in 'make headers_check' output. Fix it by looking in the right place instead.

* Basic implementation of 'make headers_check'David Woodhouse2006-06-181-0/+11
| | | | | | | | Based on the 'headers_install' target, this performs a basic sanity check on the exported headers -- so far only checking that they do not include any other headers which aren't selected for import, but easily extendable. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
* Basic implementation of 'make headers_install'David Woodhouse2006-06-181-0/+147
This adds a make target which exports a subset of headers which contain definitions which are useful for system libraries and tools. It uses the BSD 'unifdef' tool to remove instances of #ifdef __KERNEL__, and uses sed to remove markers like __user.
