无法编译 boost::fiber 个官方示例
cannot compile boost::fiber official examples
我正在试用 boost::fiber 库，但我无法使用 boost fiber 编译代码。因此我转而编译和 运行 boost 官方示例。我安装了最新版本的boost library 1.65.1，安装似乎没问题。我执行了以下命令来编译 simple.cpp
g++ -I /usr/local/include/boost/ -L /usr/local/lib/ -lboost_fiber -std=c++11 libs/fiber/examples/simple.cpp
