Build EmberLite

EmberLite uses CMake (≥ 3.16 recommended) and optionally the same Kconfig → build/.config → build/config.cmake pipeline as OpenEmber.

Requirements

• Linux (POSIX)
• CMake ≥ 3.16
• GCC or Clang with C11

Recommended: ember one-shot

From the EmberLite repository root:

chmod +x ./scripts/ember   # once
./scripts/ember build

Behavior:

• Creates a default non-interactive .config if build/.config is missing.
• Generates build/config.cmake, then runs cmake -S . -B build and cmake --build.
• First menuconfig may download kconfig-frontends-nox to .kconfig-frontends/ (needs curl, dpkg-deb, etc.; directory is gitignored).

Common commands:

Command	Purpose
./scripts/ember menuconfig [build_dir]	Interactive Kconfig → .config + config.cmake
./scripts/ember genconfig [build_dir]	Regenerate config.cmake only
./scripts/ember update [build_dir]	cmake -S . -B <dir>
./scripts/ember clean [build_dir]	Remove build directory

Plain CMake (no Kconfig)

mkdir -p build
cmake -S . -B build
cmake --build build -j

Artifacts: binaries in build/bin/, libraries in build/lib/.

Example: UART terminal

./build/bin/hal_uart_term -d /dev/ttyUSB0 -b 115200

If serial access fails, add your user to the dialout group and re-login.
