Using the MongoDB C++ Driver with MNMLSTC instead of Boost ---------------------------------------------------------- The MongoDB C++ driver Debian package is built with the Boost C++17 polyfill. In the event that you would rather use the MNMLSTC/core C++17 polyfill, you can simply obtain the mongo-cxx-driver source package and rebuild it. To enable the MNMLSTC/core C++17 polyfill use the pkg.mongo-cxx-driver.mnmlstc build profile and ensure that your build environment has network access enabled. The first can be accomplished by setting the environment variable DEB_BUILD_PROFILES="pkg.mongo-cxx-driver.mnmlstc" and the second when building by passing the option --git-pbuilder-options="--use-network yes" (for building with git-buildpackage) or possibly just "--use-network yes" (for building with pbuilder). Enabling network access is required so that the upstream part of the build can clone the MNMLSTC/core GitHub project.
