FreeBSD에서 AddressSanitizer 지원 활성화

문제는 본질적으로 FreeBSD에서 AddressSanitizer를 사용하는 프로그램을 컴파일하는 방법입니다.

저는 FreeBSD 10.0(64비트)을 사용하고 있습니다. 플래그를 사용하여 다음 코드를 컴파일하려고 합니다 -fsanitize=address.

int main() {
  return 0;
}

clangas 를 사용하여 컴파일 하면 clang -fsanitize=address file.c다음과 같은 오류 메시지가 나타납니다.

/tmp/t-tEh7oh.o: In function `main`:
file.c:(.text+0xc4): undefined reference to `__asan_report_store4`
/tmp/t-tEh7oh.o: In function `asan.module_ctor`:
file.c:(.text+0x119): undefined reference to `__asan_init_v3`
clang: error: linker command failed with exit code 1 (use -v to see invocation)

gcc48as 를 사용하여 컴파일 하면 gcc48 -fsanitize=address file.c다음과 같은 오류 메시지가 나타납니다.

/usr/local/bin/ld: cannot find -lasan
collect2: error: ld returned 1 exit status

libasan.*내 GNU/Linux 시스템의 파일 시스템 어딘가에 파일이 있습니다. 하지만 FreeBSD에서는 찾을 수 없습니다 . /usr/ports.pkg

어떻게 하면 더 잘 작동하게 해야 할까요?

고쳐 쓰다.gcc48 -v의견에 대한 응답으로 출력 (보다 정확하게는 출력 gcc48 -fsanitize=address file.c -v) 을 추가했습니다 .

Using built-in specs.
