# Build-only: compiles the C++ cryptonote native addon (lethean-util)
# Requires the Lethean blockchain source tree mounted/copied alongside.
#
# Build context must be the parent directory (zano-upstream/), e.g.:
#   docker build -f zano-node-util/Dockerfile -t lethean-util .
#
# The blockchain repo is expected at ./blockchain (symlinked as Lethean inside the package).
