Add cc-name to klibc/scripts/Kbuild.include. Make optimization flags not supported by clang conditional on cc-name. Use "--print-file-name=include" and "--print-libgcc-file-name" when using clang. Use cc-option to enable compiler-specific flags. Mark "bcmp" as not a builtin to prevent clang from using it. Signed-off-by: Bill Wendling <morbo at google.com>

From: Michael Davidson <md at google.com> Add cc-name to klibc/scripts/Kbuild.include. Make optimization flags not supported by clang conditional on cc-name. Don't use -nostdinc when building klibc. While klibc doesn't (shouldn't) use the standard header files supplied by the toolchain, it does still need to be able to find the compiler-specific header file

Generate dependencies almost like done by fixdep in the kernel. This teaches make to rebuild cpio image when content has changed. Also restructured usr/Kbuild a little so we better utilise parallel makes (dash, gzip, utils and kinit are now build in parallel). Signed-off-by: Sam Ravnborg <sam@ravnborg.org> --- patch is on top of hpa's linux tree, so path differ if applied to the klibc

With the following patch kbuild now supports: make usr/dash/arith_yylex.i make usr/klibc/umount.o make usr/klibc/umount.s Patch does also fix indention of CPP command Signed-off-by: Sam Ravnborg <sam@ravnborg.org> --- That was my number 5) item on the kbuild list (added by akpm). Modulus the next bug hpa discover this should clear all kbuild issues with klibc. So I hope to see it in next

Avoiding full path to KLIBCINC will result in havesyscall.h being generated in the $(objtree). We do not want generated files in the source tree with make O=.. -I parmeters to gcc now prefixed with $(srctree) allowing to pick up the generated .h file in $(objtree) Signed-off-by: Sam Ravnborg <sam@ravnborg.org> --- diff --git a/scripts/Kbuild.klibc b/scripts/Kbuild.klibc index

This reverts commit 9d8d648e604026b32cad00a84ed6c29cbd157641, which broke signal handing on some architectures. On m68k and parisc, signal return depends on a trampoline that the kernel writes on the stack. On alpha, s390, and sparc (32-bit), we can avoid this by providing our own function as sa_restorer, but we currently don't. Signed-off-by: Ben Hutchings <ben at decadent.org.uk>

Hi, From the Makefile I figured that to build klibc where the kernel was built with O=/someotherdir, you need to do: make KLIBCKERNELOBJ=/someotherdir KBUILD_SRC=1 Everything seems fine though, but it fails to link dash with: ----- KLIBCCC dash/bltin/printf.o KLIBCCC dash/system.o KLIBCCC dash/bltin/test.o KLIBCCC dash/bltin/times.o KLIBCCC dash/var.o GEN dash/init.c KLIBCCC

Hi Bryan and other klibc people. I have taken a stamp on the Makefiles for klibc, this is what I came up with. 1) No longer recompile on every invocation 2) Correct checking on dependencies 3) Simpler makefile syntax (almost all over the place) I compile-time tested it only. Two open issues: a) Do we realy use .a files for initramfs. I renemed that to the executable. b) I renamed

Hi, I wanted to test the kinit setup on my configuration, and I found out that I'm unable to build using an external object directory (i.e. using O=../dir). I'm using the sources from the GIT tree. The first problem is in usr/dask/Kbuild, in the invocations of mktokens; with O= the build system will try to execute something like:
