From 6ad8db533c7d53a85e6280da1ad88ed4077258fb Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Fri, 20 Feb 2015 10:25:11 +0000 Subject: [PATCH] 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. Extend target gcc headers search to musl too Upstream-Status: Inappropriate [embedded specific] Signed-off-by: Paul Eggleton Signed-off-by: Khem Raj --- gcc/Makefile.in | 2 ++ gcc/config/linux.h | 8 ++++++++ gcc/config/rs6000/sysv4.h | 8 ++++++++ gcc/cppdefault.cc | 4 ++++ 4 files changed, 22 insertions(+) diff --git a/gcc/Makefile.in b/gcc/Makefile.in index 956437df95b..6a009c696e9 100644 --- a/gcc/Makefile.in +++ b/gcc/Makefile.in @@ -671,6 +671,7 @@ libexecdir = @libexecdir@ # Directory in which the compiler finds libraries etc. libsubdir = $(libdir)/gcc/$(real_target_noncanonical)/$(version)$(accel_dir_suffix) +libsubdir_target = $(target_noncanonical)/$(version) # Directory in which the compiler finds executables libexecsubdir = $(libexecdir)/gcc/$(real_target_noncanonical)/$(version)$(accel_dir_suffix) # Directory in which all plugin resources are installed @@ -3199,6 +3200,7 @@ CFLAGS-intl.o += -DLOCALEDIR=\"$(localedir)\" PREPROCESSOR_DEFINES = \ -DGCC_INCLUDE_DIR=\"$(libsubdir)/include\" \ + -DGCC_INCLUDE_SUBDIR_TARGET=\"$(libsubdir_target)/include\" \ -DFIXED_INCLUDE_DIR=\"$(libsubdir)/include-fixed\" \ -DGPLUSPLUS_INCLUDE_DIR=\"$(gcc_gxx_include_dir)\" \ -DGPLUSPLUS_INCLUDE_DIR_ADD_SYSROOT=$(gcc_gxx_include_dir_add_sysroot) \ diff --git a/gcc/config/linux.h b/gcc/config/linux.h index e36f32bf59e..c6aada42eb7 100644 --- a/gcc/config/linux.h +++ b/gcc/config/linux.h @@ -157,6 +157,13 @@ see the files COPYING3 and COPYING.RUNTIME respectively.
