当我尝试编译使用boost :: filesystem库的代码时,我一直运行错误。我不明白我得到的任何编译器输出。下面是从http://www.highscore.de/cpp/boost/dateisystem.html#dateisystem_pfadangaben复制我的代码:C++ boost :: filesystem未定义对`boost :: filesystem3 :: path :: root_name()const'的引用
#include <boost/filesystem.hpp>
#include <iostream>
int main(){
boost::filesystem::path p("C:\\Windows\\System");
std::cout << p.root_name() << std::endl;
std::cout << p.root_directory() << std::endl;
std::cout << p.root_path() << std::endl;
std::cout << p.relative_path() << std::endl;
std::cout << p.parent_path() << std::endl;
std::cout << p.filename() << std::endl;
}
我的Ubuntu 11.10和我已经安装了libbost-dev的和g ++。这就是终端的样子:
