Solved Implement MongoDB with Qt: mongocxx

[SGaist]

Hi and welcome to devnet,

What error are you getting exactly ?

[Arush Gupta]

Hi,
I get file not found errors on these lines:

#include <bsoncxx/json.hpp>
#include <mongocxx/client.hpp>
#include <mongocxx/stdx.hpp>
#include <mongocxx/uri.hpp>
#include <mongocxx/instance.hpp>

Thanks

@Arush-Gupta
This is not my area, so may not be correct, but while you wait for an expert to comment....

    -I/usr/local/include/mongocxx/v_noabi \
    -I/usr/local/include/bsoncxx/v_noabi

This tells compiler to look in those two directories for files. But your includes read #include <mongocxx/instance.hpp> etc. So to find those paths it needs (presumably) to look down from /usr/local/include to find /usr/local/include/mongocxx/instance.hpp (assuming that is correct). In which case, if compiler does not already look automatically in /usr/local/include (I don't know if it does) you would need -I/usr/local/include?

Hi,
Thanks for the response
But that does not fix it :(
.pro:

INCLUDEPATH += \
    -I/usr/local/include/

LIBS += \
    -L/usr/local/lib \
    -lmongocxx \
    -lbsoncxx

Thanks

Where are the files you include located on your hard drive exactly ?

[Arush Gupta]

Hi,
/usr/local/include/mongocxx/v_noabi/ contains folder mongocxx and /usr/local/include/bsoncxx/v_noabi/ contains folder bsoncxx.
Thanks

I see your issue now. Go back to the original paths you were using but remove the -I before the path, they are unneeded with the INCLUDEPATH variable.

Hi,
Thanks it worked, I was able to import it, but another issue poped up:

error: 'bsoncxx::v_noabi::builder::stream' has not been declared
   20 | using bsoncxx::builder::stream::close_array;
      |                         ^~~~~~

But I can see folder stream inside builder inside bsoncxx.
In the error I see that it want's to import bsoncxx::v_noabi::builder::stream but I want it to use bsoncxx::v_noabi::bsoncxx::builder::stream
Thanks

That I do not know.

Can you provide a minimal example that triggers this error ?

[Arush Gupta]

Sorry for the late response,
I solved the issue by reinstalling the packages
Thanks for the help.
