Question

所以我正在尝试使用SSL ergo Apache Openssl和SSLeay安装Apache。我已经完成了Apache2和Openssl，知道我在安装SSLeay时遇到了困难。在所有命令都失败后，我得到perl Makefile.PL。

perl Makefile.PL    
Found multiple possibilities for OpenSSL
      /opt/ssl (OpenSSL 0.9.8r)
      /usr (OpenSSL 0.9.8p)
    Which SSL install path do you want to use? [/opt/ssl]

build information

================================================

ssl library: OpenSSL 0.9.8r in /opt/ssl
ssl header:  openssl/ssl.h
libraries:   -L/opt/ssl/lib -lssl -lcrypto -lgcc
include dir: -I/opt/ssl/include

================================================

Note (probably harmless): No library found for -lgcc
Writing Makefile for Crypt::SSLeay
The test suite can attempt to connect to public servers
to ensure that the code is working properly. If you are
behind a strict firewall or have no network connectivity,
these tests may fail (through no fault of the code).
Do you want to run the live tests (y/N)? [N]

我选择了/ usr安装，因为那是我安装openssl-devel的安装，因为我查看this question, that is simmilar并发现需要openssl-devel。所以我安装了openssl-devel

但是当我运行make

时，我知道仍然会出现以下错误

我认为原因是perl找不到openssl-devel库，如果是这样，我如何链接它以便找到它。

提前感谢Almightybob

Answer 1

为什么不使用预先为您的发行版构建的版本？

$ sudo yum install perl-Crypt-SSLeay

（或一些近似的等价物）

Answer 2

如果找不到库，通常会出现undefined symbol错误。这看起来更像它找到了库但不喜欢它。您是否有可能尝试使用64位perl的32位openssl或反之亦然？

Answer 3

你对这些软件感到困惑。

在openSUSE和相关的发行版上，只需sudo zypper install apache2。 Apache httpd v2已经包含一个名为mod_ssl的OpenSSL绑定;此命令将自动安装所有必要的依赖关系到SSL上的服务内容，包括OpenSSL库。编译任何东西都不需要。

SSLeay是Perl HTTP 客户端堆栈的一部分。通过SSL访问远程服务器上的其他人的内容是很好的。这与您想要的相反，但如果您仍然需要，请先add the repository devel:language:perl，然后安装包perl-LWP-Protocol-https。同样，这将自动引入所需的依赖关系，包括perl-Net-SSLeay。

要添加通常与Apache Web服务器一起使用的Perl内容，请添加存储库Apache:Modules，然后还安装包apache2-mod_apreq2，apache2-mod_perl，libapreq2 ，perl-Apache2-Request。

在Linux上安装Crypt :: SSLeay时出错
