Hi,
linux 6.13~rc7-1~exp1 fails to cross build from source with build=amd64 and
host=arm64 like this:
cc -g -O2 -Werror=implicit-function-declaration
-ffile-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong
-fstack-clash-protection -Wformat -Werror=format-security
-mbranch-protection=standard -Wall -Wdate-time -D_FORTIFY_SOURCE=2

lib/cpufreq.c
make[4]: *** [Makefile:193:
/<<PKGBUILDDIR>>/debian/build/build-tools/tools/power/cpupower/lib/cpufreq.o]
Error 1
cc: error: unrecognized command-line option ‘-mbranch-protection=standard’
This is a regression introduced by this upstream commit:
f79473ed922023942407da25cb00843ac28b981c
Reverting it fixes the problem. The commit essentially replaces LD=$(CROSS)gcc
with LD?=$(CROSS)gcc so that the flags can be overridden. From the commit
message:
pm: cpupower: Makefile: Allow overriding cross-compiling env params
Allow overriding the cross-comple env parameters to make it
easier for Yocto users. Then cross-compiler toolchains to build
cpupower with only two steps:
- source (toolchain path)/environment-setup-armv8a-poky-linux
- make
I suspect that the Debian packaging can fix this by not overriding these
settings with the wrong values?
Thanks!
cheers, josch
