Include kvm_test_harness.h first which will include kselftest_harness.h for _GNU_SOURCE to get defined first before inclusion of stdio.h. It is required for declaration of asprintf(). It removes the following build error caught by clang-17: In file included from x86_64/fix_hypercall_test.c:12: In file included from include/kvm_test_harness.h:11: ../kselftest_harness.h:1169:2: error: call to undeclared function 'asprintf'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] 1169 | asprintf(&test_name, "%s%s%s.%s", f->name, | ^ Signed-off-by: Muhammad Usama Anjum <usama.anjum@xxxxxxxxxxxxx> --- tools/testing/selftests/kvm/x86_64/fix_hypercall_test.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/kvm/x86_64/fix_hypercall_test.c b/tools/testing/selftests/kvm/x86_64/fix_hypercall_test.c index f3c2239228b10..75306dcfaad6c 100644 --- a/tools/testing/selftests/kvm/x86_64/fix_hypercall_test.c +++ b/tools/testing/selftests/kvm/x86_64/fix_hypercall_test.c @@ -4,12 +4,12 @@ * * Tests for KVM paravirtual feature disablement */ +#include "kvm_test_harness.h" #include <asm/kvm_para.h> #include <linux/kvm_para.h> #include <linux/stringify.h> #include <stdint.h> -#include "kvm_test_harness.h" #include "apic.h" #include "test_util.h" #include "kvm_util.h" -- 2.39.2
