[Verse 1] Your desktop runs x86, but the target's ARM Different architectures, keeping code from harm Cross-compilation bridges this divide Building executables for the other side GCC with triple flags, host to target leap Architecture, vendor, system secrets deep [Chorus] Cross compile, different chip Toolchain magic, bridge the gap Linker scripts map memory space Build systems orchestrate the race From source to binary, architecture shift Cross-compilation is the developer's gift [Verse 2] Target triple tells the story straight Arm-linux-gnueabihf, don't hesitate Sysroot holds the libraries you need Headers and runtime for target's breed Environment variables point the way CC and CXX for compilation's play [Chorus] Cross compile, different chip Toolchain magic, bridge the gap Linker scripts map memory space Build systems orchestrate the race From source to binary, architecture shift Cross-compilation is the developer's gift [Bridge] Linker script defines where sections go Text in ROM, data starts below Stack pointer set, interrupt vectors placed Memory layout perfectly embraced FLASH and RAM regions carved precise Firmware boot sequence, location's dice [Verse 3] CMake toolchain files automate the task Set the compiler, no need to ask Buildroot crafts the entire chain From kernel config to application's gain Yocto recipes layer by layer Embedded systems' royal player [Chorus] Cross compile, different chip Toolchain magic, bridge the gap Linker scripts map memory space Build systems orchestrate the race From source to binary, architecture shift Cross-compilation is the developer's gift [Outro] Desktop builds for distant cores Cross-compilation opens doors Different targets, single source Toolchain mastery stays the course
