This check should have been there from the beginning and for
every
header
file. It's big PITA to sync this list up, especially when dealing
with
different glibc or kernel than OE-Core, e.g. external toolchains,
etc.
Any objections to making this check more generic for every entry
in
the list?
Yes, a strong objection. We don't want to support or encourage
every
kernel version out there.
I also don't understand why people need to change the libc-headers
anyway :(
I already explained my use-case with external toolchains - those
usually come
with specific set of libc-headers. And when those don't match the
list from
OE-Core, it causes problems, trying to support some resemblance of
multilib.
I believe that got disabled completely now for external-toolchains
anyway...
Right, external toolchains I can understand having specific version
requirements. What I don't really understand is external toolchains
would come with their own headers in most cases I can think of?
this is not a freestanding toolchain, but hosted one, so they need to
provide OS (linux) headers. think of case where apps are build just by
using this toolchain outside OE, app devs are not expected to provide
these headers.
Cheers,
Richard
