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?
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

一般来说,当你在Debian或Ubuntu上丢失了一个开发文件(或任何其他文件)时,使用apt-file来找出哪个包提供了该文件:
~ apt-file search openssl/bio.h
android-libboringssl-dev: /usr/include/android/openssl/bio.h
libssl-dev: /usr/include/openssl/bio.h
libwolfssl-dev: /usr/include/cyassl/openssl/bio.h
libwolfssl-dev: /usr/include/wolfssl/openssl/bio.h
快速浏览命令返回的每个包,使用apt show将告诉您在这些包中寻找哪个包:
~ apt show libssl-dev
