如何在Ubuntu上安装OpenSSL C ++库？ [英] How do I install the OpenSSL C++ library on Ubuntu?

问题描述

我试图在Ubuntu 10.04 LTS上使用OpenSSL 1.0.0构建一些代码。当我运行make，它调用g ++与-lssl选项。来源包括：

  #include< openssl / bio.h> 
 #include< openssl / buffer.h> 
 #include< openssl / des.h> 
 #include< openssl / evp.h> 
 #include< openssl / pem.h> 
 #include< openssl / rsa.h> 
  

我跑了：

  $ sudo apt-get install openssl 
读取软件包列表...完成
构建依赖关系树
读取状态信息...完成
 openssl已经是最新版本。 
 0升级，0新安装，0删除和3未升级。 
  

但我想openssl包不包括库。我得到这些错误make：

  foo.cpp：21：25：错误：openssl / bio.h：没有这样的文件或目录
 foo.cpp：22：28：错误：openssl / buffer.h：没有这样的文件或目录
 foo.cpp：23：25：错误：openssl / des.h：没有这样的文件或目录
 foo.cpp：24：25：错误：openssl / evp.h：没有这样的文件或目录
 foo.cpp：25：25：错误：openssl / pem.h：没有这样的文件或目录
 foo.cpp：26：25：错误：openssl / rsa.h：没有这样的文件或目录
  

如何在Ubuntu 10.04 LTS上安装OpenSSL C ++库？

我做了一个 man g ++ 和（在选项链接）为-l选项它声明：链接器搜索标准目录列表的库...和搜索的目录包括几个标准系统目录...是那些标准系统目录？

更新：答案是 sudo apt-get install libssl-dev 。我怎么能想出自己（除了在这里提出这个问题）？我可以以某种方式告诉apt-get列出所有的包，和grep的ssl？或者我需要知道lib * -dev命名约定吗？

解决方案

要安装开发包是libssl-dev：

  sudo apt-get install libssl-dev

I'm trying to build some code on Ubuntu 10.04 LTS that uses OpenSSL 1.0.0.  When I run make, it invokes g++ with the "-lssl" option.  The source includes:
#include <openssl/bio.h>
#include <openssl/buffer.h>
#include <openssl/des.h>
#include <openssl/evp.h>
#include <openssl/pem.h>
#include <openssl/rsa.h>
I ran:
$ sudo apt-get install openssl
Reading package lists... Done
Building dependency tree       
Reading state information... Done
openssl is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.
But I guess the openssl package doesn't include the library.  I get these errors on make:
foo.cpp:21:25: error: openssl/bio.h: No such file or directory
foo.cpp:22:28: error: openssl/buffer.h: No such file or directory
foo.cpp:23:25: error: openssl/des.h: No such file or directory
foo.cpp:24:25: error: openssl/evp.h: No such file or directory
foo.cpp:25:25: error: openssl/pem.h: No such file or directory
foo.cpp:26:25: error: openssl/rsa.h: No such file or directory
How do I install the OpenSSL C++ library on Ubuntu 10.04 LTS?

I did a man g++ and (under "Options for Linking") for the -l option it states: " The linker searches a standard list of directories for the library..." and "The directories searched include several standard system directories..."  What are those standard system directories?

Update: The answer is sudo apt-get install libssl-dev.  How could I have figured that out for myself (other than asking this question here)?  Can I somehow tell apt-get to list all packages, and grep for ssl?  Or do I need to know the "lib*-dev" naming convention?
解决方案
You want to install the development package, which is libssl-dev:
sudo apt-get install libssl-dev
