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?


当前回答

您需要安装开发包,即libssl-dev:

sudo apt-get install libssl-dev

其他回答

Run:

apt-get install libssl-dev

安装libcurl4-openssl-dev

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

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
