charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: linux-kernel-mentees-bounces@lists.linuxfoundation.org Sender: "Linux-kernel-mentees" This patch series aims at removing the dependency on execute bit of the scripts in the kbuild system. If not working with fresh clone of linux-next, clean the srctree: make distclean make tools/clean To test the dependency on execute bits, I tried building the kernel after removing x-bits for all files in the repository. Removing execute bits: for i in $(find -executable -type f); do chmod -x $i; done Any attempts to configure (or build) the kernel fail because of 'Permission denied' on scripts with the following error: $ make allmodconfig sh: ./scripts/gcc-version.sh: Permission denied init/Kconfig:34: syntax error init/Kconfig:33: invalid statement init/Kconfig:34: invalid statement sh: ./scripts/ld-version.sh: Permission denied init/Kconfig:39: syntax error init/Kconfig:38: invalid statement sh: ./scripts/clang-version.sh: Permission denied init/Kconfig:49: syntax error init/Kconfig:48: invalid statement make[1]: *** [scripts/kconfig/Makefile:71: allmodconfig] Error 1 make: *** [Makefile:606: allmodconfig] Error 2 Changes: 1. Adds specific interpreters (in Kconfig) to invoke scripts. After this patch I could successfully do a kernel build without any errors. 2. Again adds specific interpreters to other parts of kbuild system. I could successfully perform the following make targets after applying the second patch: make headerdep make kselftest-merge Following changes in the patch 2/2 are not yet tested: arch/* scripts/* Ujjwal Kumar (2): kconfig: use interpreters to invoke scripts kbuild: use interpreters to invoke scripts Makefile | 4 ++-- arch/arm64/kernel/vdso/Makefile | 2 +- arch/arm64/kernel/vdso32/Makefile | 2 +- arch/ia64/Makefile | 4 ++-- arch/nds32/kernel/vdso/Makefile | 2 +- init/Kconfig | 16 ++++++++-------- scripts/Makefile.build | 2 +- scripts/Makefile.package | 4 ++-- 8 files changed, 18 insertions(+), 18 deletions(-) -- 2.26.2 _______________________________________________ Linux-kernel-mentees mailing list Linux-kernel-mentees@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/linux-kernel-mentees
