Hi Lakshmi -

You will need to use the MongoDB C++ driver within your Qt application. You can find instructions on how to download, build, and use the MongoDB C++Driver here: http://docs.mongodb.org/ecosystem/drivers/cpp/

Detailed instructions on how to build the driver are here: http://docs.mongodb.org/ecosystem/tutorial/download-and-compile-cpp-driver/

Please let me know if there is anything else I can do to help.

Thanks,

Andrew

It seems to me that the bulk of the work is mapping between various lower level types in bsoncxx::stdx and Qt. I wonder if you would consider providing a Qt-friendly API wrapper that uses things like QString/QStringRef instead of bsoncxx::stdx::string_view? I wouldn't think that it would be more than just a very thin layer on top of the existing code, and it could go a long way toward opening up MongoDB C++ to the Qt community.

Hi Scott -

We would need to think carefully about how to enable such a feature. One of the goals of the C++11 driver was to have no third party library dependencies, other than libbson and libmongoc. But I certainly support the goal of making the new driver easy to use with Qt.

I think the best thing to do would be to file an enhancement request in the CXX JIRA project. It wouldn't be a priority for us right now (shipping the 1.0.0 release is), but that way this idea would still be on our radar. Of course, you are welcome to send PRs as well.
