How to use the mongodb.natvis with the mongocxx c++ lib?

Caio_Cesar1 · 2025-03-31T15:36:01.666Z

Using vcpkg I have compiled the mongo c++ lib “mongo-cxx-driver” GitHub - mongodb/mongo-cxx-driver: C++ Driver for MongoDB

while debugging i can see that it have added a "v_noabi" namespace everywhere in the files, folders and also on the variables types (see image attached)

I’m trying to use the mongodb.natvis to preview these variables values on the debugger

github.com/mongodb/mongo

buildscripts/win/mongodb.natvis

master

  To load in Visual Studio, the natvis file must be in the Visual Studio project.
   Note: with buildscripts/setup_spawnhost_coredump, this file should be automatically placed in the user-specific Natvis directory.

  <Type Name="mongo::Status">
    <DisplayString Condition="_error == 0x0">OK</DisplayString>
    <DisplayString>{{Error={_error,d}}}</DisplayString>
  </Type>

This file has been truncated. show original

but the natvis doesnt include the v_noabi namespace.

What i’m missing? i need to compile the lib with this thing of v_noabi disabled or what?
