C++ - Conversion std::basic_string<char>

Question

Brace yourselves! C++ newbie question incoming:

Can someone explain to me why this error occurs and how should I fix it?

std::vector<std::string> options = vectorOGROptions_.get()

I want to get options var as std::vector<std::string> but it seems my vectorOGROptions property returns a different type..

error: conversion from ‘const std::basic_string<char>’ to non-scalar type ‘std::vector<std::basic_string<char> >’ requested

Assuming you're using C++03 and not C++11, do std::vector<std::string> options(1, vectorOGROptions_.get());. — legends2k

Your get() function returns string, but you are trying to initialize vector with this string, that's not allowed.

You can use something like this

std::vector<std::string> options; options.push_back(vectorOGROptions.get());

You are trying to assign to a vector a string. You cannot do this. Use an initialiser list.

std::vector<std::string> options{vectorOGROptions_.get()};

The error says that this get() function returns const std::basic_string<char>, which is nothing but std::string. Use vector's push_back() method:

std::vector<std::string> options; options.push_back(vectorOGROptions_.get());
