链接nghttp2静态库
Linking nghttp2 static library
我想在 C++ 中使用 nghtt2_asio 编译一个简单的服务器应用程序。
它在共享库下完美编译：
g++ server.cpp -O2 -std=c++20 -Wall -Wextra -lnghttp2_asio -lboost_system -lssl -lcrypto -o server
但是当我静态编译它时：
g++ server.cpp -static -O2 -std=c++20 -Wall -Wextra -o server -lssl -ldl -pthread -lcrypto -ldl -pthread -lnghttp2_asio -lboost_system
链接器给我这些错误：

有人可以向我解释发生了什么吗？
Can someone explain me what happens?
这里有几个问题。
您有未解析的符号。如n.m。在评论中说，你需要添加 -libnghttp2.
您在 link 行的库顺序错误。较低级别的库应该 在 link 行上跟随 较高级别的库。正确的顺序是这样的：
-lnghttp2_asio -libnghttp2 -lboost_system -lssl -lcrypto -ldl
请参阅 this blog post 了解说明。
- 您正在 link 创建一个完全静态的二进制文件。
与流行的看法相反，此类二进制文件（至少在 Linux 上）显着 不如动态 linked 的可移植性。
警告告诉你的是 IF 你试图 运行 在安装了不同版本 GLIBC 的系统上运行这个二进制文件（可能是不同的系统来自于您构建的系统，甚至 相同 系统但在升级到不同版本的 GLIBC 之后），那么您的二进制文件可能会崩溃（并且很可能会崩溃）。
不做完全静态 link。
你会 很多
注意：您不必动态地 link 反对 libnghttp2_asio 等，只需反对 libc 和 libdl 和 libcrypto。

有人可以向我解释发生了什么吗？
Can someone explain me what happens?
这里有几个问题。
您有未解析的符号。如n.m。在评论中说，你需要添加
-libnghttp2.您在 link 行的库顺序错误。较低级别的库应该 在 link 行上跟随 较高级别的库。正确的顺序是这样的：
-lnghttp2_asio -libnghttp2 -lboost_system -lssl -lcrypto -ldl
请参阅 this blog post 了解说明。
- 您正在 link 创建一个完全静态的二进制文件。
与流行的看法相反，此类二进制文件（至少在 Linux 上）显着 不如动态 linked 的可移植性。
警告告诉你的是 IF 你试图 运行 在安装了不同版本 GLIBC 的系统上运行这个二进制文件（可能是不同的系统来自于您构建的系统，甚至 相同 系统但在升级到不同版本的 GLIBC 之后），那么您的二进制文件可能会崩溃（并且很可能会崩溃）。
不做完全静态 link。
你会 很多注意：您不必动态地 link 反对 libnghttp2_asio 等，只需反对 libc 和 libdl 和 libcrypto。
