Carbon’s interop lets you call existing C++ code directly with zero overhead. Use carbon::cpp and extern \"C++\" to import C++ symbols, and export to expose Carbon to C++. This blog shows a concrete example, explains ABI guarantees, and lists trade‑offs.
Global CMake commands like include_directories leak settings into unrelated targets. Switching to target properties with PRIVATE/INTERFACE/PUBLIC visibility fixes dependency management for good.
Replace classic polymorphism with C++17’s std::variant and std::visit. Learn why variants are faster, how to use them, and when they’re not the best fit.
Global include paths pollute builds; target-based CMake replaces them with target properties and PUBLIC PRIVATE INTERFACE visibility keywords.
Learn how to transition from the LLVM Legacy Pass Manager to the New Pass Manager (NPM) to improve IR pipeline efficiency and modularity.
Learn how to spot and fix crashes caused by std::vector reallocation that invalidates pointers, references, or iterators, using reserve, indices, and sanitizers.
Learn how CLion automatically updates its CMake model when you add a library target, what enables instant code completion, and when you may need to reload manually.
Learn how to create a Gazebo model plugin that applies a constant force, with build instructions, loading steps, and a discussion of version‑locking and stability trade‑offs.
Learn how to call a C++ function from Carbon by creating an extern "C" wrapper, compiling it to an object file, and linking with carbonc --link-with.
