1From 9427c6cedf88e15f747c48cb4fcf9eda6f5c4555 Mon Sep 17 00:00:00 2001 2From: Khem Raj <raj.khem@gmail.com> 3Date: Fri, 20 Feb 2015 10:25:11 +0000 4Subject: [PATCH] Ensure target gcc headers can be included 5 6There are a few headers installed as part of the OpenEmbedded 7gcc-runtime target (omp.h, ssp/*.h). Being installed from a recipe 8built for the target architecture, these are within the target 9sysroot and not cross/nativesdk; thus they weren't able to be 10found by gcc with the existing search paths. Add support for 11picking up these headers under the sysroot supplied on the gcc 12command line in order to resolve this. 13 14Extend target gcc headers search to musl too 15 16Upstream-Status: Pending 17 18Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com> 19Signed-off-by: Khem Raj <raj.khem@gmail.com> 20--- 21 gcc/Makefile.in | 2 ++ 22 gcc/config/linux.h | 8 ++++++++ 23 gcc/config/rs6000/sysv4.h | 8 ++++++++ 24 gcc/cppdefault.c | 4 ++++ 25 4 files changed, 22 insertions(+) 26 27diff --git a/gcc/Makefile.in b/gcc/Makefile.in 28index d1d4512bba3..06eb0d27a28 100644 29--- a/gcc/Makefile.in 30+++ b/gcc/Makefile.in 31@@ -630,6 +630,7 @@ libexecdir = @libexecdir@ 32 33 # Directory in which the compiler finds libraries etc. 34 libsubdir = $(libdir)/gcc/$(real_target_noncanonical)/$(version)$(accel_dir_suffix) 35+libsubdir_target = $(target_noncanonical)/$(version) 36 # Directory in which the compiler finds executables 37 libexecsubdir = $(libexecdir)/gcc/$(real_target_noncanonical)/$(version)$(accel_dir_suffix) 38 # Directory in which all plugin resources are installed 39@@ -3009,6 +3010,7 @@ CFLAGS-intl.o += -DLOCALEDIR=\"$(localedir)\" 40 41 PREPROCESSOR_DEFINES = \ 42 -DGCC_INCLUDE_DIR=\"$(libsubdir)/include\" \ 43+ -DGCC_INCLUDE_SUBDIR_TARGET=\"$(libsubdir_target)/include\" \ 44 -DFIXED_INCLUDE_DIR=\"$(libsubdir)/include-fixed\" \ 45 -DGPLUSPLUS_INCLUDE_DIR=\"$(gcc_gxx_include_dir)\" \ 46 -DGPLUSPLUS_INCLUDE_DIR_ADD_SYSROOT=$(gcc_gxx_include_dir_add_sysroot) \ 47diff --git a/gcc/config/linux.h b/gcc/config/linux.h 48index 87efc5f69fe..b525bcd56b3 100644 49--- a/gcc/config/linux.h 50+++ b/gcc/config/linux.h 51@@ -165,6 +165,13 @@ see the files COPYING3 and COPYING.RUNTIME respectively.
