c ++ <vector>没有命名类型

Question

所以我在我的c ++程序中遇到了一些类型问题.这是代码:

#include "NHSFileparser.h"
#include "NHSFileController.h"
#include <string>
#include <vector>       

std::string databasepath = "/media/sf_Documents/Skola/MVK/testdb/";
std::string dblang = "english";
std::vector<std::string> directories;
std::string directory1 = "/media/sf_Documents/Skola/MVK/testdata/";
std::string directory2 = "/media/sf_Documents/Skola/MVK/testdata2/";
directories.push_back(directory1);
directories.push_back(directory2);
std::vector<std::string> queryterms;
std::vector<std::string> return_files;

int main() {
NHSFileController fc(directory1, databasepath);
bool b = fc.addDirectory(directory1);
NHSDatabase database(databasepath, dblang);
split( queryterms, "test", boost::is_any_of("_")); //Split on lots of chars
std::cout << "Queryterms set." << std::endl;
database.query(queryterms, return_files);
std::cout << return_files.size() << std::endl;
if (return_files.size() > 0){
    std::cout << "File found: " << return_files[0] << std::endl;
}
return 0;
}

当我在Ubuntu 12.04上使用g++ 4.6和编译时,-std=c++0x我收到以下错误:

    error: ‘directories’ does not name a type

在两行尝试push_back到目录矢量.

到目前为止我发现的一切都是没有正确地声明std :: vector的问题,我(据我所知)已经完成了.

您不能将语句放在函数之外,只能声明声明和定义.把你的代码放在里面main.
