Make menuconfig

For Developers
1

Hi All,
I have noticed that after setting "kernel profiling" via make menuconfig, I can see that the options is set in .config

$ grep PROFIL .config
CONFIG_KERNEL_PROFILING=y

however, when I start an openwrt build I see a message early on saying

#
# configuration written to .config
#

and when I check .config I see

$ grep PROFIL .config
# CONFIG_KERNEL_PROFILING is not set

So, my changes made via make menuconfig are lost when the .config is rebuilt.

Is there someplace else where I can set options so that they are retained for the build?

Thanks for your help,
John Alfredo

You can try in make kernel_menuconfig, but this sounds like a bug anyway, probably want to report it.

I tried the make kernel_menuconfig, and saw that the .config that was written was in

./build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2_alex/linux-ramips_mt7688/linux-3.18.27/.config

However, just as before, after I started a build CONFIG_PROFILING was unset in this location.

What is the procedure for reporting this?

AFAIK, reporting is limited to source which is being actively developed.
