From e5caec9a8626da42ad71e10893c6cf5b671c3487 Mon Sep 17 00:00:00 2001 From: Max Filippov <jcmvbkbc@gmail.com> Date: Thu, 16 Mar 2017 15:23:55 -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 <jcmvbkbc@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com> --- tools/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/Makefile b/tools/Makefile index a894b5c9d2..e9cde02c90 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 $@ -- 2.39.5
