Debian上未指定EVP_idea_ecb的引用

问题描述

我有以下代码：

  #include< stdio.h> 
 #include< stdlib.h> 
 #include< openssl / evp.h> 
 int main（int argc，char * argv []）{
 EVP_CIPHER * cipher; 
 EVP_idea_ecb（）; 
} 
  

我知道这不是很多，但应该没有投诉，但是我得到

  gcc Testfile.c -lssl -lcrypto 
 Testfile.c :( .text + 0xec）：未定义参考`EVP_idea_ecb'
 
 gcc Testfile.c -lss 
 / usr / bin / ld：/tmp/ccgbkhFA.o：对'EVP_CIPHER_iv_length @@ OPENSSL_1.0.0'的未定义引用
 //usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0：添加符号错误：命令中缺少DSO 
  

libssl-dev 已安装。任何想法这里出现什么问题？

我的发行版：Debian Jessie on x64。

解决方案

一行一行：

  gcc Testfile.c -lssl -lcrypto 
 Testfile.c :( .text + 0xec）：未定义的引用EVP_idea_ecb
  

Debian的OpenSSL库Jessie x64不包含EVP_idea_ecb。

  gcc Testfile.c -lss 
 / usr / bin / ld：/ tmp / ccgbkhFA.o：未定义的引用符号'EVP_CIPHER_iv_length @@ OPENSSL_1.0.0'
 //usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0：错误添加符号：DSO从命令中丢失linel 
  

libss2so从libss2命令行界面库包中也没有帮助。 p>

I have the following code:

#include <stdio.h>
#include <stdlib.h>
#include <openssl/evp.h>
int main (int argc, char *argv[]) {
    EVP_CIPHER *cipher;
    EVP_idea_ecb();
}

I know, this is not much, but it should compile without complaints, but I get

gcc Testfile.c -lssl -lcrypto
Testfile.c:(.text+0xec): undefined reference to `EVP_idea_ecb'

gcc Testfile.c -lss
/usr/bin/ld: /tmp/ccgbkhFA.o: undefined reference to symbol 'EVP_CIPHER_iv_length@@OPENSSL_1.0.0'
//usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0: error adding symbols: DSO missing from command linel

libssl-dev are installed. Any ideas what is going wrong here?

My distro: Debian Jessie on x64.

解决方案

What is going on line by line:

gcc Testfile.c -lssl -lcrypto
Testfile.c:(.text+0xec): undefined reference to `EVP_idea_ecb'

OpenSSL library of Debian Jessie x64 doesn't contain EVP_idea_ecb.

gcc Testfile.c -lss
/usr/bin/ld: /tmp/ccgbkhFA.o: undefined reference to symbol 'EVP_CIPHER_iv_length@@OPENSSL_1.0.0'
//usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0: error adding symbols: DSO missing from command linel

libss.so.2.0 from libss2 command line interface library package doesn't help either.
