CMake and linking

Canonical Grok16 Field CMake + g16-ld mandate for speed_demo and all field targets.

CMake configure build link pipeline — Configure → g16 compile → g16-ld link with field mandate flags

speed_demo CMake project

examples/speed-demo/CMakeLists.txt builds grok16_speed_demo from speed_demo.cpp.

Host plane

cmake -S examples/speed-demo -B build/host \
  -DCMAKE_CXX_COMPILER=$(which g++) \
  -DGROK16_HOST_PLANE=ON
cmake --build build/host -j$(nproc)

G16 belt plane

cmake -S examples/speed-demo -B build/g16 \
  -DCMAKE_TOOLCHAIN_FILE=$G16_PREFIX/cmake/grok16-toolchain.cmake \
  -DGROK16_PROFILE=belt_2_0
cmake --build build/g16 -j$(nproc)

Toolchain file

cmake/grok16-toolchain.cmake sets:

CMAKE_C_COMPILER / CMAKE_CXX_COMPILER → g16
Profile flags from data/grok16-profiles.json
Linker wrapper → g16-ld

Linking mandate

File	Role
`cmake/g16-linker-mandate.cmake`	Field link flags, `-pie`, shared rules
`cmake/g16-field-mandate.cmake`	`G16_FIELD_SAFETY_MANDATE_v1` on field targets
`forge/g16-linker.py`	`g16-ld` backend — 16 target families
