From 7807af13118eff3ac291bbaaf2159c7a441c0902 Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Thu, 16 Mar 2017 11:21:58 -0700 Subject: [PATCH] Pass empty CFLAGS on invocation of libfdt/setup.py When building u-boot tools in cross-build environment CFLAGS environment variable set up for target is taken into an account when building code for host. Make it empty on invocation of python. This fixes the following build errors when cross-compiling for xtensa: cc1: error: unrecognized command line option "-mlongcalls" cc1: error: unrecognized command line option "-mauto-litpools" Signed-off-by: Max Filippov Reviewed-by: Simon Glass --- tools/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/Makefile b/tools/Makefile index 1c840d7..f3de657 100644 --- a/tools/Makefile +++ b/tools/Makefile @@ -120,7 +120,7 @@ _libfdt.so-sharedobjs += $(LIBFDT_OBJS) libfdt: tools/_libfdt.so: $(patsubst %.o,%.c,$(LIBFDT_OBJS)) tools/libfdt_wrap.c - LDFLAGS="$(HOSTLDFLAGS)" python $(srctree)/lib/libfdt/setup.py \ + LDFLAGS="$(HOSTLDFLAGS)" CFLAGS= python $(srctree)/lib/libfdt/setup.py \ "$(_hostc_flags)" $^ mv _libfdt.so $@ -- 2.1.4
