From: Johannes Berg <[email protected]> Since kernel 5.8, specifically commit 4d0831e8a029 ("kconfig: unify cc-option and as-option"), 'make kernelversion' will call into the Kconfig system, evaluating cc-option from scripts/Kconfig.include, which requires a writable current working directory due to the use of ".tmp_<pid>" for temporary files. This was fixed upstream in commit 805b2e1d427a ("kbuild: include Makefile.compiler only when compiler is needed"). To work around it, pass M= as suggested here: https://lore.kernel.org/r/CAK7LNAROdVMPQq4Qn_M=OWzJrfqNOc4fyMicNKdnCqu7G9rFgw@mail.gmail.com Signed-off-by: Johannes Berg <[email protected]> --- backport/Makefile | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/backport/Makefile b/backport/Makefile index ee7df4ba29ce..77c2670d637e 100644 --- a/backport/Makefile +++ b/backport/Makefile @@ -84,8 +84,8 @@ mrproper: echo "" ;\ done \ ) > Kconfig.kernel ;\ - kver=$$($(MAKE) --no-print-directory -C $(KLIB_BUILD) kernelversion | \ - sed 's/^\(\([3-5]\|2\.6\)\.[0-9]\+\).*/\1/;t;d') ;\ + kver=$$($(MAKE) --no-print-directory -C $(KLIB_BUILD) M=$(BACKPORT_DIR) \ + kernelversion | sed 's/^\(\([3-5]\|2\.6\)\.[0-9]\+\).*/\1/;t;d');\ test "$$kver" != "" || echo "Kernel version parse failed!" ;\ test "$$kver" != "" ;\ kvers="$$(seq 14 39 | sed 's/^/2.6./')" ;\ -- 2.30.2 -- To unsubscribe from this list: send the line "unsubscribe backports" in
