From 182057b80891edc0e8d46835e2d8bfd28330a55a Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Fri, 20 Feb 2015 10:25:11 +0000 Subject: [PATCH 19/39] Ensure target gcc headers can be included There are a few headers installed as part of the OpenEmbedded gcc-runtime target (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.
