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:
- Adds specific interpreters (in Kconfig) to invoke
scripts.
After this patch I could successfully do a kernel build
without any errors.
- Again, adds specific interpreters to other parts of
kbuild system.
I could successfully perform the following make targets after
applying the PATCH 2/2:
make headerdep
make kselftest-merge
make rpm-pkg
make perf-tar-src-pkg
make ARCH=ia64 defconfig
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make prepare
Following changes in PATCH 2/2 are not yet tested:
arch/arm64/kernel/vdso32/Makefile
arch/nds32/kernel/vdso/Makefile
scripts/Makefile.build
