I'd like to have all packages built use a custom
-mcpu=cortex-a72 thus providing optimized binaries for my RPi4. Is there a way in the
nconfig to set this globally? If not, can someone recommend a method?
I did find the following which seems to only ass the CFLAGS to the kernel package, not to any package:
[*] Advanced configuration options (for developers) --->
(-mcpu=cortex-a72) Kernel extra CFLAGS
Thanks for suggestions!
I did find this link on the wiki but I don't know how to modify the file to use my
EDIT: I tried modifying
rules.mk appending my flag and that seems to be working:
TARGET_CFLAGS:=$(TARGET_OPTIMIZATION)$(if $(CONFIG_DEBUG), -g3) $(call qstrip,$(CONFIG_EXTRA_OPTIMIZATION))
TARGET_CXXFLAGS = $(TARGET_CFLAGS)
Go little lower, there's "Target Options" and inside of it "Target Optimizations".
Nice, thank you for pointing that out. I do not want to modify
rules.mk and using that variable is much more modular.
