Updated - Xplatcppwindowsdll

Introduction The software development landscape has long been defined by a central tension: the desire for native performance and the need for cross-platform compatibility. For C++ developers, this often translates into building shared libraries (DLLs on Windows, SOs on Linux, DYLIBS on macOS) that can be called from higher-level applications written in Python, C#, or even JavaScript.

find_package(xplatcpp REQUIRED) add_xplatcpp_dll(MyEngine SOURCES engine.cpp COMPILE_DEFINITIONS _CRT_SECURE_NO_WARNINGS ) xplatcppwindowsdll updated

Replace your own export macros with #include <xplatcpp/api.h> and tag public classes/functions with XPLATCPP_PUBLIC . update your manifest:

Recently, the development team behind the project rolled out a significant update. This update—codenamed "Harmony Bridge"—is a game-changer for engineers working at the intersection of portable C++ code and the Windows platform. SOs on Linux

Set CMAKE_MSVC_RUNTIME_LIBRARY consistently across all projects. 🔴 Pitfall 2: C++ Exceptions Crossing DLL Boundaries Throwing an exception from a DLL and catching it in the main executable is unsafe if they aren’t compiled with the same compiler and EH flags. The updated toolchain optionally wraps all public functions with a std::error_code facade.
