我正在尝试用 C++ 构建一个节俭服务器，但我似乎在链接阶段遇到了问题。任何人都可以解释一下吗？

这就是我正在运行的。（请原谅我是 C++ n00b）：

g++ -Wall -L/usr/local/lib  user_constants.o user_types.o UserService_server.o -lthrift

这是输出

您的构建线看起来有点“细”。您确定您正在获取库 using-L和库本身 using的所有位置-l吗？

综上所述，我想说 Boost 和 Apache 是罪魁祸首。你必须单独链接它们吗？此外，请记住，与某些架构相比，库路径变量（通常LD_LIBRARY_PATH）需要在链接时和运行时设置为构建命令行上的路径。

Usual thrift generates three .cpp file for each interface (*.thrift) you should add all of them ( UserService.cpp and UserService_constants.cpp, UserService_types.cpp ) to g++ arguments.
