笔记。我已经看到并阅读了 Boost::asio::ssl OpenSSL not compile
我在 linux fedora 64 上构建 boost 示例 ssl 服务器时遇到了一些问题，我认为它的版本是 15 或 16。它是一台大学机器，所以我们没有 root 访问权限，因为周末我通过 SSH 访问机器。我们没有root，也没有安装openssl。我没有构建boost库，示例服务器构建良好。然后我尝试openssl从源代码构建最新的库。我提取到~/Dev/opensslSource
Cd ~/Dev/opensslSource
./config --prefix=~/Dev/openssl --openssldir=~/Dev/openssl
Make
Make install
现在问题存在于那里或我如何包含和链接。所以然后在我的 boostexamples 文件夹中，我确实保存了示例sslserver.cpp 并使用以下内容进行构建。
g++ -I ~/Dev/boost_1_52_0/ -I ~/Dev/openssl/include -L ~/Dev/boost_1_52_0/stage/lib -L ~/Dev/openssl server.cpp -o server -lboost_system -lssl –lpthread
错误几乎是无穷无尽的。我什至都看不到他们。但我相信它们都只是不明确的参考。

因此，在前几条评论之后，我将构建更改为。
g++ -I ~/Dev/boost_1_52_0/ -I ~/Dev/openssl/include -L ~/Dev/boost_1_52_0/stage/lib –L ~/Dev/openssl/lib server.cpp -o server -lboost_system -lssl -lcrypto -lpthread
现在出错。
