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 $ make run-user SYSROOT=1 // test without sysroot, using nolibc.h directly $ make run-user SYSROOT=0 Signed-off-by: Zhangjin Wu --- tools/testing/selftests/nolibc/Makefile | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/tools/testing/selftests/nolibc/Makefile b/tools/testing/selftests/nolibc/Makefile index 848884204a84..0b66b7a79cea 100644 --- a/tools/testing/selftests/nolibc/Makefile +++ b/tools/testing/selftests/nolibc/Makefile @@ -102,6 +102,9 @@ REPORT ?= awk '/\[OK\][\r]*$$/{p++} /\[FAIL\][\r]*$$/{f++;print} /\[SKIPPED\][\ END{ printf("%d test(s) passed, %d skipped, %d failed.\n", p, s, f); \ printf("See all results in %s\n", ARGV[1]); }' +# allow switch nolibc headers include method: 1 for sysroot, 0 for nolibc.h +SYSROOT ?= 1 + help: @echo "Supported targets under selftests/nolibc:" @echo " all call the \"run\" target below" @@ -139,9 +142,15 @@ sysroot/$(ARCH)/include: $(Q)$(MAKE) -C ../../../include/nolibc ARCH=$(ARCH) OUTPUT=$(CURDIR)/sysroot/ headers_standalone $(Q)mv sysroot/sysroot sysroot/$(ARCH) +ifeq ($(SYSROOT), 1) nolibc-test: nolibc-test.c sysroot/$(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 libc-test: nolibc-test.c $(QUIET_CC)$(CC) -o $@ $<
