Hello, I hope someone can help me with this. I can build normally in a Development Editor config without issues. However, if I try to build in Shipping/Development/DebugGame config, I get the below error. I’m using the header-only Boost::geometry library. The library’s headers are added in a separate module’s Build.cs with PublicIncludePaths. Then, I add that module to my game’s Build.cs PrivateDependencyModuleNames. I did try including the headers along with my game c++ classes, but got the same errors.

ProceduralTile.cpp is my C++ class, and it includes boost.
I’d appreciate any insight into this you can provide. Thanks.
Edit: I have discovered a workaround. changing references from std::bad_cast to std::exception in the boost numeric_conversion avoids the link error in shipping configs.
