Mongo-c-driver in Windows LNK2019 unresolved external symbol __imp___getpid referenced in function _mongoc_log

[Jay]

I've been following this documentation https://mongodb.github.io/mongo-cxx-driver/mongocxx-v3/installation to setup a C++ application with mongDB.

The pre-existing application is a Win32 DLL project to be used with SierraChart https://www.sierrachart.com/index.php?page=doc/UsingVisualCPlusPlus.php#CreateProject. I've previously integrated UnQlite into the application but it's time to convert to something a little more cloud friendly.  

I've installed libbson, mongo-c-driver and mongo-cxx-driver via the following:

Installing Libbson:

cd libbson-1.8.0

Here is the database.cpp I have added to be included in the existing project:

#include "database.h"


#include <cstdlib>
#include <iostream>
#include <string>


#include <bsoncxx/builder/stream/document.hpp>
#include <bsoncxx/json.hpp>
#include <bsoncxx/stdx/make_unique.hpp>


#include <mongocxx/client.hpp>
#include <mongocxx/instance.hpp>
#include <mongocxx/logger.hpp>

/**

Database::Database()
{
}


/**

 */
Database::~Database()
{
}


/**
 * Connects to the Database instance.
 */
void Database::Connect()
{
 using bsoncxx::builder::stream::document;


 mongocxx::instance inst{};
}

The following are the errors I get when I attempt to build the solution:

Severity Code Description Project File Line Suppression State
Error LNK2019 unresolved external symbol __imp___getpid referenced in function _mongoc_log StorageConnect E:\Trading\SierraChartStudies\SwingStudy\StorageConnect\mongoc-static-1.0.lib(mongoc-log.obj) 1

Initially it appears as though it's similar to https://jira.mongodb.org/browse/CDRIVER-2054 which was solved with an update to libmongoc where __declspec(dll*) was being added to all API function declarations unconditionally.

Any help on this would be greatly appreciated. Hopefully it's something small I've missed with the initial setup.

Hi - 

I have a theory about this, after thinking about it for some time now.

You said that you are setting "all ... projects to MTd and MT". That implies two different builds. But the target library names don't vary with those settings. Are you installing the resulting binaries to the same place? Do you think you may have overwritten the MTd builds of one driver (c or c++) with MT builds, thus resulting in a binary directory that has mixed runtime linkage?

I'd propose that you build and install the MT and MTd versions of mongo-c-driver and mongo-cxx-driver to different locations.

Eventually, I would like to see both the C driver and C++ driver use boost like ABI tagging in the filename to avoid exactly this issue (and, while we are at it, use #pragma comment to auto-inject the library name).

Could you retry your build, using only one mode (e.g. MT or MTd) consistently for all builds (c driver, c++ driver, application) and see if the issues go away?

Thanks,

Andrew

Thanks for the help on this one Andrew!

You were right, there was incorrect linkage occurring with the build path. Even though I had updated the runtime libraries to be used, I was still building to the same target directory and it was preventing the updated binaries to be built and installed. All projects are building as expected now. Greatly appreciate the help.

[Andrew Morrow]

Great! I'm happy to hear that my guess proved helpful. Hopefully we will do ABI tagging and auto-linking sometime soon and this will all get simpler.

Hello,

I am currently facing the same problem, but I  can't figure out how to fix it.

What are the practical steps you did to solve it?

Thaaaank you

I am currently facing the same problem, but I can’t figure out how to fix it.

Hi Reda,

Could you please open a new discussion thread along with the following details:

• libbson version, installation command and output.
• mongo-c-driver version, installation command and output.
• mongo-cxx-driver version, installation command and output.
• Any error message that you’re getting.
• Any additional details, i.e. PATHs, etc.

This would make it easier for someone to help debug the problem.

What are the practical steps you did to solve it?

Based on the discussion above , a retry of the build using only one mode (e.g. MT or MTd) consistently for all builds (c driver, c++ driver, application) solved the problem.

Kind regards,
Wan.
