my qt creator version is Qt 5.11.2

QtCreator version does not matter. QtCreator is just an IDE.
What matters is Qt version.
Did you use exact same compiler to build Mongodb driver as you use to build your app?
How do you use the Mongodb driver? Please show your pro file.

Change \ to / and do a complete rebuild.
Also, please post the error message you get, it is not clear which lib exactly is not found.

mongocxx/events/command_failed_event.cpp

Isn't this part of Mongo cxx driver?

Vivek_A

@jsulm sorry for that , i removed some includes .now the error is

g++: error: â€œ\c\mongo-cxx-driver\lib\mongoc-1.0.libâ€: No such file or directory
g++: error: â€œ\c\mongo-cxx-driver\lib\bson-1.0.libâ€: No such file or directory.

i know its not there, in my case in mongodb lib folder there is no .lib file , in above screenshot showing that there is .A file , so how to fix that.

Hi,

@Vivek_A said in issues in Mongodb driver with Qt creator:

mongoc-1.0.libâ€: No such file or directory

You have some strange maybe invisible char(s) in your file.
Remove them

@SGaist & @jsulm ok, i tried linking lib by this link https://doc.qt.io/qtcreator/creator-project-qmake-libraries.html.

after clicking and setting as external library
linking code came in pro file like this

win32:CONFIG(release, debug|release): LIBS += -LC:/mongo-cxx-driver/lib/ -llibmongocxx.dll
else:win32:CONFIG(debug, debug|release): LIBS += -LC:/mongo-cxx-driver/lib/ -llibmongocxx.dlld

INCLUDEPATH += C:/mongo-cxx-driver/include
DEPENDPATH += C:/mongo-cxx-driver/include

after that i added ```
#include <mongocxx/client.hpp>

in main.cpp but error coming no such file or directory...please check...!!!

SGaist

Where is client.hpp located exactly on your disc ?

Vivek_A

@SGaist @jsulm
my compiler is mingw32bit and mongocxx driver build in 64 bit . so thats make problem , i solved it by installing 64bit Qt.
Then i started coding i have added all heders and
the created application of pushbutton ,. when push button clicked mongodb will insrt data . but when i building and run the app , its closing down.

12:49:58: Starting C:\Users\LD-RD2\Documents\build-mongo2-Desktop_Qt_6_1_2_MinGW_64_bit-Debug\debug\mongo2.exe ...

:-1: warning: An exception was triggered: 
Exception at 0x7ffa8d37d1a0, code: 0xc0000135: DLL not found, flags=0x0.

i tested with removing all other mongodb codes and teated with only one statement mongocxx::instance inst; but still same problem.... Any idea???

SGaist

Can the MongoDB dlls be found at run time ?
