Masahiro Yamada 02aff85922 kbuild: check the minimum linker version in Kconfig ... Unify the two scripts/ld-version.sh and scripts/lld-version.sh, and check the minimum linker version like scripts/cc-version.sh did. I tested this script for some corner cases reported in the past: - GNU ld version 2.25-15.fc23 as reported by commit 8083013fc3 ("ld-version: Fix it on Fedora") - GNU ld (GNU Binutils) 2.20.1.20100303 as reported by commit 0d61ed17dd ("ld-version: Drop the 4th and 5th version components") This script show an error message if the linker is too old: $ make LD=ld.lld-9 SYNC include/config/auto.conf *** *** Linker is too old. *** Your LLD version: 9.0.1 *** Minimum LLD version: 10.0.1 *** scripts/Kconfig.include:50: Sorry, this linker is not supported. make[2]: *** [scripts/kconfig/Makefile:71: syncconfig] Error 1 make[1]: *** [Makefile:600: syncconfig] Error 2 make: *** [Makefile:708: include/config/auto.conf] Error 2 I also moved the check for gold to this script, so gold is still rejected: $ make LD=gold SYNC include/config/auto.conf gold linker is not supported as it is not capable of linking the kernel proper. scripts/Kconfig.include:50: Sorry, this linker is not supported. make[2]: *** [scripts/kconfig/Makefile:71: syncconfig] Error 1 make[1]: *** [Makefile:600: syncconfig] Error 2 make: *** [Makefile:708: include/config/auto.conf] Error 2 Thanks to David Laight for suggesting shell script improvements.
