Kernel v4.14 and newer contain the following in their Makefile:

This breaks our menuconfig, because it can no longer find ncurses if its
not on the host machine. This can be seen in linux-yocto-dev, for
example:
[clsulliv@clsulliv build]$ bitbake virtual/kernel -c menuconfig
GEN ./Makefile
HOSTLD scripts/kconfig/mconf
/home/clsulliv/yocto/poky/build/tmp/hosttools/ld: cannot find -lncurses

Does this fix still require a kernel patch ? I was trying to test
it out here, and may have messed up the steps.
If I remove ncurses-dev from my builder, I'm not able to get a
working menuconfig no matter what combination of this patch
applied (or not) or my menuconfig patch applied (or not).
I can say that having this applied didn't break my menuconfig,
but I wasn't able to fully test.
Should I expect a builder without ncurses-dev + just this patch
to be able to run menuconfig ?
We still need the patch "menuconfig,check-lxdiaglog.sh: Allow
specification of ncurses location", as seen here:
https://git.yoctoproject.org/cgit/cgit.cgi/linux-yocto-dev/commit/?h=standard/base&id=26911f4ada6374ff3f0b7f98364b7a93756a180b
Two separate fixes in the same area unfortunately.
Locally I am doing 'bitbake linux-yocto-dev -c menuconfig' and I am
getting a working menuconfig with my patch, and no ncurses-dev(el)
installed on my host machine. If you're not, I worry that there might be
more host contamination that we haven't discovered.
Could you share the errors you're hitting?
I retested this morning, since I was doing a lot of different things
yesterday .. and I wanted to be sure that I had things right.
During my new tests, I can get menuconfig to launch with ncurses-dev
removed on my builder, if I have your patch + the one I carry in
linux-yocto.
It was my revert of the kernel patch that was getting me into the
"never able to build menuconfig" loop.
So no issues with this change, it doesn't break anything and definitely
lets me launch menuconfig when ncurses-dev isn't present on the builder.
I'll resend that kernel patch upstream.

Thanks,

Fix this by setting HOSTLDFLAGS to ${BUILD_LDFLAGS} in our
'make menuconfig' command.
