Cross compiled kernel headers are installed into /usr/*-linux-gnu/include/ instead of /usr/*-linux-gnu/sys-root/usr/include/ where they can be found by default by the Fedora cross compiler toolchain.
Because the kernel-cross-headers package can be installed without the cross glibc-* binutils-* gcc-* counterparts, it has to own the sysroot directory.

Is that a new change in how the cross compilers work? The original patch was added a long time ago based on the cross compiler behavior in Fedora at the time. If that's changed, where can we see that documented?

Hi Josh,
Thx for rising this point. I've tried to sum-up my current understanding in rhbz#1642037.
Basically this is the first time I'm using the fedora cross toolchain to build userland applications. I've reproduced this error in f28, f29. I haven't tested in in f27 yet. I confirm it's possible to build some applications with the arm-linux-gnu fedora toolchain once the glibc-arm-linux-gnu is installed. But as an example, the bug occurs as soon as the <errno.h> header is included from a hello.c.
As a side note I will be AFAIK later today until one week. So unless a solution is found I won't be able to work on this issue until back.
Thx

The Fedora cross toolchains are only built to cross-compile kernels. It even says so right in the description:
Description : Cross-build GNU C compiler. : : Only building kernels is currently supported. Support for : cross-building user space programs is not currently provided as : that would massively multiply the number of packages.
I think you've hit an error in a usecase the toolchains don't even support.
