与OpenSSL的链接错误 [英] Link error with OpenSSL

问题描述

我已经安装了OpenSSL。我只是想使用OpenSSL运行一个程序。

I have installed OpenSSL . I just want to run a program using OpenSSL.

下面是我的程序，从这里 拍摄。

Here is my program, taken from here .

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "openssl/aes.h"

int main(int argc, char* argv[])
{
  AES_KEY aesKey_;
  unsigned char userKey_[16];
  unsigned char in_[16];
  unsigned char out_[16];
  strcpy(userKey_,"0123456789123456");
  strcpy(in_,"0123456789123456");

  fprintf(stdout,"Original message: %s", in_);
  AES_set_encrypt_key(userKey_, 128, &aesKey_);
  AES_encrypt(in_, out_, &aesKey_);

  AES_set_decrypt_key(userKey_, 128, &aesKey_);
  AES_decrypt(out_, in_,&aesKey_);
  fprintf(stdout,"Recovered Original message: %s", in_);      
  return 0;
}

在编译时我因为有相同的错误消息的程序，但解决的办法只要不为我工作。

While compiling the program I got the same error messages as there, but the solution provided there is not working for me.

我仍然得到编译错误。

I am still getting compile error.

$ gcc -I/home/bholanath/Sources/openssl-1.0.1e/include/ op.c -lcrypt 

/tmp/ccvHr9Jr.o: In function `main':
op.c:(.text+0x9c): undefined reference to `AES_set_encrypt_key'
op.c:(.text+0xbc): undefined reference to `AES_encrypt'
op.c:(.text+0xd7): undefined reference to `AES_set_decrypt_key'
op.c:(.text+0xf7): undefined reference to `AES_decrypt'
collect2: error: ld returned 1 exit status

$ gcc op.c -lcrypt 

/tmp/ccDEZMog.o: In function `main':
op.c:(.text+0x9c): undefined reference to `AES_set_encrypt_key'
op.c:(.text+0xbc): undefined reference to `AES_encrypt'
op.c:(.text+0xd7): undefined reference to `AES_set_decrypt_key'
op.c:(.text+0xf7): undefined reference to `AES_decrypt'
collect2: error: ld returned 1 exit status

任何帮助去除编译错误和运行我的程序将是巨大的。
我使用在Fedora Linux系统GCC。

Any help to remove compilation error and run my program will be great. I am using GCC under Fedora linux.

推荐答案

OpenSSL库名称是 libcrypto 和的libssl 。尝试联系起来。 libcrypt 是的glibc的一部分。

The OpenSSL library names are libcrypto and libssl. Try linking them. libcrypt is part of glibc.

此外，您code是无效。
