I have trying to connect my Matlab with MongoDB using the mongoc function in Matlab R 2021b version.
But I am having this error -
Files\MATLAB\R2021b\bin\win64\builtins\database_builtins\mwlibmongo_builtinimpl.dll failed with error: not connected: not connected
The specified module could not be found.
Below is my code;
addpath( [ '..' filesep 'MALARIA' filesep 'C Driver' filesep 'mongo-c-driver-1.17.6.tar.gz'] );
server = '127.0.0.1';
port = 27017;
dbname = "TestDB";
% Connect to server
conn = mongoc(server,port,dbname) ;

Hi,
I fixed the error installing visualcode c++ prior installing the database toolbox.
the connector using the mongodb c++ driver, it's required I guess during the installation.

Hi,
The issue is probably because a module used inside this library is missing. It is advised to check if all the necessary modules and packages are installed in your machine. You may look into "mongoc" function documentation for further information. In order to identify what modules are missing, you may leverage Dependency Walker for the same. Please look into this link for further clarity.

Hi,
I am experiencing the same issue on win10 and R2021b. I used Dependency Walker, but at first glance it gives me the same uninformative messages as matlab.
I tried manually loading the dll
>>> loadlibrary('C:\Program Files\MATLAB\R2021b\bin\win64\builtins\database_builtins\mwlibmongo_builtinimpl.dll')
Error using loadlibrary
Could not find file mwlibmongo_builtinimpl.h.
Indeed I cannot locate this header file under
C:\Program Files\MATLAB\R2021b\extern\include
or any other path in the R2021b folder.
I am hitting 0 results on google for which library provides such file. Any ideas on how to proceed further?

You cannot add a file with addpath() . MATLAB will not automatically expand the file and look inside it.
Also, if what you posted is the complete message, then you are having a problem with spaces in the directory name of the DLL -- but it is not obvious at the moment why that particular DLL was being looked for.
