[Buildroot] Buildroot error

[Michael Brainerd]

I have a build error that I am unable to find documentation to debug the issue.
See attached build error text, and .config file.

My host is:

 Either the linux tree in uClinux-dist is so old that it doesn't have the
"headers_install" target yet (I think that's from 2.6.10-ish), or the tree
you're pointing to is not actually a linux tree. In the first case, you also
misconfigured your kernel headers, because you claim it's 4.7. But you probably
just took the first thing you saw :-)

 Arnout

uClinux-dist is the name of the "distribution" around uClinux, and
uClinux-dist is pretty much a build system, like Buildroot. So it seems
like Michael has used the source code of a build system, and offered it
to Buildroot as the source of the Linux kernel. Obviously, this isn't
going to work very well.

all,
Then there is no way to specify uClinux as the image to build?

What are you trying to do exactly? For which architecture/platform are
you trying to build a kernel?

uClinux is pretty much useless these days, both common noMMU
architectures are supported by the regular Linux kernel.

Best regards,
