Tooling & Build

Lessons in this group, roughly in build order:

• preprocessor-macros — The preprocessor is a textual pass that runs before the compiler, rewriting the source via include,…
• header-source-separation — C++ splits code into headers (.h/.hpp, declarations the compiler shares) and source files (.cpp,…
• build-systems-cmake-make — A build system turns source files into binaries by tracking dependencies and invoking the compiler/linker…
• package-managers-vcpkg-conan — vcpkg and Conan fetch, build, and expose third-party C++ libraries with their transitive dependencies,…
• debuggers-gdb-lldb — gdb (GNU) and lldb (LLVM) are interactive symbolic debuggers that stop a running program at chosen points…
• sanitizers-asan-ubsan-tsan — Sanitizers are compiler-inserted runtime checks (in GCC and Clang) that detect memory errors, undefined…
• static-analysis-clang-tidy-cppcheck — Static analyzers inspect source code without running it, flagging bugs, undefined behavior, and style…
• profilers-perf-valgrind — Profilers measure where a program spends time or memory at runtime; perf samples real hardware counters…
• unit-testing-googletest-catch2 — GoogleTest and Catch2 are C++ frameworks for writing and running automated unit tests, providing assertion…
• modules-c-20 — C++20 modules replace textual include with a compiled, importable interface unit, giving real…
