我在 ubuntu 18.04 中使用了 clang-10。

我试图用内存清理器构建共享库。

#include <stdio.h>

int foo(int argc, char** argv) {
    int* a = new int[10];
    a[5] = 0;
    if (a[argc])
    printf("xx\n");
  return 0;
}

构建的对象：

clang++ -c foo.cpp -o foo.o -fsanitize=memory -fPIC

然后我尝试将它链接到共享库：

clang++  -Wl,--no-undefined -shared -Wl,-soname,libFoo.so -o libFoo.so foo.o

在此命令之后，我得到了错误输出：

foo.o: In function `foo(int, char**)':
foo.cpp:(.text+0xf): undefined reference to `__msan_param_tls'
foo.cpp:(.text+0x68): undefined reference to `__msan_retval_tls'

foo.o: In function `msan.module_ctor':
foo.cpp:(.text+0x1d2): undefined reference to `__msan_init'
clang: error: linker command failed with exit code 1 (use -v to see invocation)

.so使用内存清理器构建文件的正确命令是什么？
