我想将Library cpp-netlib用于C++项目.因此我在自制软件的帮助下安装了boost库(操作系统是Mac OS X 10.8).然后我从项目主页下载了cpp-netlib,使用cmake为g ++创建了Makefile并成功应用了make."make test"通过了所有测试.然后我将cpp-netlib的include文件夹复制到boost目录中.
所以这就是麻烦开始的时候:我试图编译文档的第一个示例http-client,但无法使其工作.我用的时候
g++ test.cpp -o out -I/usr/local/Cellar/boost/1.53.0/include
-L/usr/local/Cellar/boost/1.53.0/lib
-lboost_system-mt -lboost_filesystem-mt -lboost_thread-mt
我收到了这些链接器错误:
