I am encountering compile errors building off master. My build system

anyone else that had the same problem.
One of the errors is below:

I ran into this issue when building 4.8-pre for F23 and F24
(https://fedoraproject.org/wiki/Kernel_Vanilla_Repositories ). If you
want to just circumvent this problem install the kernel-headers package
from at least 4.7 (from my repos or the kernel-stabilization repo) in
your build environment. Those headers contain everything that is needed
to compile the iio tools from 4.8-pre. I haven't reported the problem
upstream yet (-ELACKOFTIME) :-/
CU, thl
Yes, installing the new headers is the correct solution. Several of
the #defines for the IIO tools came in for 4.7. Since this is a
It would be better for the userspace tools to use the headers from the
kernel source tree instead of those from the "previous" kernel-headers
package.
This will lead to a bootstraping issue if that's not the case. Or is
there any reason why it's must use system installed headers ?
Thx
The tools aren't necessary for building the kernel itself so I don't
think there is a bootstrapping issue in the upstream project. I see
your point though and other userspace tools do use the kernel headers.
You're welcome to bring this up with the upstream maintainers and/or
submit a patch. If the patch gets acked we can bring it in.
Thanks,
Laura
