这是一个使用 openssl 库的简单 hello world sha1-hasher。

#include <openssl/sha.h>
#include <stdio.h>
#include <stdlib.h>

int main()
{
    system("printf '%s' 'hello world' | sha1sum");

    unsigned char digest[SHA_DIGEST_LENGTH];
    char digest_pr[(SHA_DIGEST_LENGTH)*2+1];
    SHA_CTX ctx;
    if(!SHA1_Init(&ctx)) return 1;
#define STR_STRLEN(A) A, (sizeof(A)/sizeof(*(A))-1)
    if(!SHA1_Update(&ctx,STR_STRLEN("hello"))) return EXIT_FAILURE;
    if(!SHA1_Update(&ctx,STR_STRLEN(" world"))) return EXIT_FAILURE;
    if(!SHA1_Final(digest,&ctx)) return EXIT_FAILURE;
    #define DIGITS "0123456789abcdef"
    for(size_t i=0;i<sizeof(digest);i++){
        digest_pr[i*2+0]=DIGITS[digest[i]/16];
        digest_pr[i*2+1]=DIGITS[digest[i]%16];
    }
    digest_pr[(SHA_DIGEST_LENGTH)*2]='\0';
    puts(digest_pr);
}

在安装了 libssl-dev 的 Mint/Ubuntu 上，我可以编译并链接它$CC sha.c（其中 CC 是 gcc、tcc 或 clang 之一）然后成功运行它，但这不适用于 musl 所以我抓住了 openssl源（git clone https://github.com/openssl/openssl），配置它./config --prefix=/usr/local/musl，构建它并安装它，现在musl-gcc sha.c -lcrypto works但运行LD_LIBRARY_PATH=/usr/local/musl/lib a.out让我：

是什么原因造成的，我该如何解决？
