使用musl编译时给出：'；重新定位时出错-找不到secure#u getenv:符号'；

我试图在x86_64 Debian上使用v1.2.1编译一个简单的C程序

程序

secgetenv.c

如下所示：

#define _GNU_SOURCE
#include <stdlib.h> 
#include <stdio.h>

int main()
{
    char *res;

    res = secure_getenv("TEST_ENV_VAR");

    fprintf(stdout, "%s\n", res);

    return 0;
}

musl在早期补丁中添加了对

secure\u getenv

的支持，我确实在

/usr/local/x86\u 64-linux-musl/include/stdlib.h

中看到了声明：

#ifdef _GNU_SOURCE
...
char *secure_getenv(const char *);
...
#endif

在

src/env/secure\u getenv.c

中有相应的定义：

#define _GNU_SOURCE
#include <stdlib.h>
#include "libc.h"

char *secure_getenv(const char *name)
{
    return libc.secure ? NULL : getenv(name);
}

我尝试将

LD_LIBRARY_PATH

设置为指向

/usr/local/x86_64-linux-musl/lib

（musl的libc所在的位置），但这似乎没有解决任何问题。我尝试了一些其他的编译器选项，但似乎没有什么可以解决它。我做错什么了吗？我如何解决这个问题

---

我想如果我添加了编译方式，可能会很有用，下面是详细的输出：
