我试图在使用OpenSSL 1.0.0的Ubuntu 10.04 LTS上构建一些代码。当我运行make时，它使用“-lssl”选项调用g++。资料来源包括:
#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:
$ 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.
但是我猜openssl包不包括这个库。我在make时得到这些错误:
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
如何在Ubuntu 10.04 LTS上安装OpenSSL c++库?
我为-l选项做了一个man g++和(在“链接选项”下)，它声明:“链接器为库搜索一个标准目录列表…”和“搜索的目录包括几个标准系统目录…”这些标准系统目录是什么?
我在这里找到了详细的解决方案:在Linux上手动安装OpenSSL
从博客文章中…
Steps to download, compile, and install are as follows (I'm installing version 1.0.1g below; please replace "1.0.1g" with your version number):
Step – 1 : Downloading OpenSSL:
Run the command as below :
$ wget http://www.openssl.org/source/openssl-1.0.1g.tar.gz
Also, download the MD5 hash to verify the integrity of the downloaded file for just varifacation purpose. In the same folder where you have downloaded the OpenSSL file from the website :
$ wget http://www.openssl.org/source/openssl-1.0.1g.tar.gz.md5
$ md5sum openssl-1.0.1g.tar.gz
$ cat openssl-1.0.1g.tar.gz.md5
Step – 2 : Extract files from the downloaded package:
$ tar -xvzf openssl-1.0.1g.tar.gz
Now, enter the directory where the package is extracted like here is openssl-1.0.1g
$ cd openssl-1.0.1g
Step – 3 : Configuration OpenSSL
Run below command with optional condition to set prefix and directory where you want to copy files and folder.
$ ./config --prefix=/usr/local/openssl --openssldir=/usr/local/openssl
You can replace “/usr/local/openssl” with the directory path where you want to copy the files and folders. But make sure while doing this steps check for any error message on terminal.
Step – 4 : Compiling OpenSSL
To compile openssl you will need to run 2 command : make, make install as below :
$ make
Note: check for any error message for verification purpose.
Step -5 : Installing OpenSSL:
$ sudo make install
Or without sudo,
$ make install
That’s it. OpenSSL has been successfully installed. You can run the version command to see if it worked or not as below :
$ /usr/local/openssl/bin/openssl version
OpenSSL 1.0.1g 7 Apr 2014
所有这些答案都是非常过时的，来自于软件包仍在开发的时候。你现在可以使用下面列出的"normal"命令:
sudo apt install openssl
编辑:OP的问题措辞很糟糕…毕竟，OpenSSL本身就是一个库，所以我在回答他的问题之前看得太快了。上面的命令安装“普通”OpenSSL。
在他的问题的末尾，他提到了make失败，这表明他正在手动编译包。是的，即使您下载了TAR球，它也将包括所有的openssl和libssl文件，然后您可以从中进行制作。
OP真正需要的是OpenSSL开发库，在这种情况下，你可以先使用上面的命令安装OpenSSL，然后再运行这个:
sudo apt install libssl-dev
