This may help to find issues about using nolibc.h to build programs. it derives from this change: commit 3a8039e289a3 ("tools/nolibc: Fix build of stdio.h due to header = ordering") Usage: // test with sysroot by default $ make run-user // test without sysroot, using nolibc.h directly $ make run-user NOLIBC_SYSROOT=3D0 Signed-off-by: Zhangjin Wu --- tools/testing/selftests/nolibc/Makefile | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/tools/testing/selftests/nolibc/Makefile b/tools/testing/selfte= sts/nolibc/Makefile index b42e67b1a7e2..f42adef87e12 100644 --- a/tools/testing/selftests/nolibc/Makefile +++ b/tools/testing/selftests/nolibc/Makefile @@ -126,9 +126,15 @@ sysroot/$(ARCH)/include: $(Q)$(MAKE) -C ../../../include/nolibc ARCH=3D$(ARCH) OUTPUT=3D$(CURDIR)/= sysroot/ headers_standalone $(Q)mv sysroot/sysroot sysroot/$(ARCH) =20 +ifneq ($(NOLIBC_SYSROOT),0) nolibc-test: nolibc-test.c sysroot/$(ARCH)/include $(QUIET_CC)$(CC) $(CFLAGS) $(LDFLAGS) -o $@ \ -nostdlib -static -Isysroot/$(ARCH)/include $< -lgcc +else +nolibc-test: nolibc-test.c + $(QUIET_CC)$(CC) $(CFLAGS) $(LDFLAGS) -o $@ \ + -nostdlib -static -include ../../../include/nolibc/nolibc.h $< -lgcc +endif =20 libc-test: nolibc-test.c $(QUIET_CC)$(CC) -o $@ $< --=20 2.25.1
