When I perform posixtestsuite, some cases failed and I got error log like this:

There is no 'linux' directory under /usr/include/ directory.

And this also causes LTP compile faild.
Comment 1 liping Ke 2011-02-15 01:23:17 UTC 
PPC should have the same problem, any file include <errno.h> will meet the problem. linux headers under target rootfs /usr/include/linux are missing for the latest changeset.
Comment 2 liping Ke 2011-02-15 01:25:20 UTC 
Also, it's missing in meta-toolchain-sdk tarball, besides target rootfs. We meet the problem in ppc build.

Thanks,
criping

This bug is there, not sure whether I have done a wrong ops to mark it as "fixed". So reopen it.

Lianhao has got the root cause and will send out the patch:

Comment 5 Lianhao Lu 2011-02-16 17:16:22 UTC 
Fixed in commits http://git.pokylinux.org/cgit/cgit.cgi/poky/commit/?id=afd4169bd24d4a14f59df5622efdcf5c6eb08eb2. 

Added RPROVIDES_${PN}-dev and RPROVIDES_${PN}-dbg for
linux-libc-headers-yocto to provides "linux-libc-headers-dev" and
"linux-libc-headers-dbg" respectively.

This resolved the dependency issue of libc6-dev depending upon
linux-libc-headers-dev. Package linux-libc-headers-yocto-dev will be
installed as linux-libc-headers-dev.
