# build_observer.sh — build the observer daemon under WSL/Linux.
# The daemon uses Linux flags and relies on libzmq + NVML on WSL's system include path.
# Do NOT build with Windows nvcc + cl.exe — it can't find zmq.h/nvml.h.
#
# Prereqs (one-time, inside WSL):
#   sudo apt install -y libzmq3-dev
#   (NVML header nvml.h ships with the CUDA toolkit at /usr/local/cuda)
#
# Run from inside WSL:  bash /mnt/d/resonance-engine-active/build_observer.sh
