Interesting. I haven't seen this myself, so just a couple of quick
questions:
- without the .config, did you still get a working set of hostprogs, and
only had to suffer the warnings ?
- If the answer is yes, then the .config really doesn't matter for this
and the approach of grabbing a .config should work fine or even
having a dummy defconfig available with enough to keep the build
happy.
Definitely sounds like something we can address and it's worth putting into
bugzilla so it doesn't get lost.
Below, please find a transcript of the commands I executed.
You'll see that I installed the SDK, tried to "make scripts," and then got
attacked with a storm of config questions. I cut off the transcript at the second
question, but there are dozens that follow.
There *is* a .config file in the SDK directory, and it is identical to the one
in our kernel build directory:
/home/pturley/yocto-mpu-build/tmp/work/dm8148_mpu-poky-linux-gnueabi/linux-ti81xx-psp-2.6.37-r0+spawnlabs+r0/git
Unfortunately, I'm still something of a n00b when it comes to building the
kernel. I suspect *most* of these questions are irrelevant to hostprogs, but I
can't say that *all* of them are.
If I just hold down the "Enter" key, I believe all the defaults are taken, and
I eventually *do* get hostprogs that execute, but I don't know if they're appropriate to
my kernel. (Again, I'm a n00b, so perhaps there's no effect at all.)
This will be fine, the defaults will work. The kernel build infrastructure
is picking up what it thinks is a change source -> to config and trying
to reconcile the differences.
If you throw in a 'make oldconfig' before you do the 'make scripts', does
that quiet things down a bit ?
Cheers,
Bruce
