This library brings the Google Maps API Web Services to your C++11 application.

The C++11 Client for Google Maps Services is a C++11 Client library for the following Google Maps APIs:

• Directions API
• Distance Matrix API
• Elevation API
• Geocoding API
• Time Zone API
• Roads API
• Places API

The latest stable version of the library can be found at:

• https://github.com/amrfaissal/gmaps11/releases/latest

• CMake v2.8 or better
• A C++11 compiler (GCC 4.8+, clang)
• CURL library
• CURLcpp C++ wrapper for CURL
• Boost library version 1.54.0+

After downloading and extracting the source from a tarball to a directory, the commands to build gmaps11 on most systems are:

mkdir build && cd build
cmake ..
cmake --build .

Installing the library and optionally specifying a prefix can be done with:

cmake -DCMAKE_INSTALL_PREFIX=/usr/local ..
cmake --build . --target install

More information on CMake can be found on its FAQ.

Before we dive into examples, please make sure you have a gmaps11.config configuration file in the root of your project.

gmaps11.config is JSON configuration file used by the C++11 client.

The Google Directions API is a service that calculates directions between locations using an HTTP request.

gmaps11 comes with a DirectionsService class to help you query The [Google Directions API]:

    #include <gmaps11/directions.hpp>
    #include <boost/scoped_ptr.hpp>
    #include <iostream>

    using namespace googlemaps;

    auto main() -> int {
        boost::scoped_ptr<DirectionsService> directions_service(new DirectionsService());
        // Query the Google Maps Directions API
        // *NOTE* 'waypoint_t' is a typdef for boost::variant which can be a
        // string holding a name (city, place...) or a boost tuple holding lat and long
        // of a position
        std::string response = directions_service->query("Paris", boost::make_tuple(44.051682, 4.643433), "driving");
        // Print the JSON response
        std::cout << response << std::endl;
    }

You can parse the JSON response using the JSON parser in gmaps11/json/json11.hpp header:

    std::string err;
    json11::Json json_body = json11::Json::parse(response, err);
    if (err.empty()) { // JSON response is valid
        std::string __status__ = json_body["status"].string_value();
    }
