CROSS-PLATFORM PITFALLS AND HOW TO AVOID THEM Erika Sweet (she/her) Microsoft C++ TeamWelcome to CppCon 2020! Visit our table at the Expo Hall https://aka.ms/cppcon/expo • Meet the Microsoft C++ (e.g. NuGet) Language specific package managers (e.g. vcpkg, Conan) Our recommendation for C++ cross-platform developmentC++ package managers: Conan, vcpkg Bring down and build libraries from source The solution spaceDebugging: the solution space Cross-platform IDEs, editors, and tools CLion, VS Code, Qt CreatorDebugging: the solution space Cross-platform IDEs, editors, and tools CLion, VS Code
