From 704c0722fd621bb7c95f9ec63413f1c6ec4fce3e Mon Sep 17 00:00:00 2001 From: Paul Eggleton Date: Thu, 22 Jan 2015 10:35:37 +0000 Subject: gcc: ensure target gcc headers can be included There are a few headers installed as part of gcc-runtime (omp.h, ssp/*.h). Being installed from a recipe built for the target architecture, these are within the target sysroot and not cross/nativesdk; thus they weren't able to be found by gcc with the existing search paths. Add support for picking up these headers under the sysroot supplied on the gcc command line in order to resolve this. Thanks to Richard Purdie for giving me a number of pointers during fixing this issue. Fixes [YOCTO #7141].
