bantam-cpp/Makefile

# Bantam (C++20 port) — POSIX-compatible Makefile.
# Targets: Linux, FreeBSD, macOS, Haiku (any POSIX make: bmake, gmake, smake).
# Dependencies: libcurl and GNU readline (found via standard include/lib
# paths) for HTTP and interactive line editing. JSON is handled by the vendored
# single-header nlohmann/json.hpp (no extra dependency).
# If your headers/libs live in a non-standard prefix, override, e.g.:
#   make CPPFLAGS="-I/opt/include" LDLIBS="-L/opt/lib -lcurl -lreadline"

# Location of the AddressSanitizer/UBSan runtime libraries plus a replacement
# libasan_preinit.o (so the runtime initializes before main()). On a normal
# system these ship with the compiler; override with
#   make debug ASANDIR=  (empty)  — the gcc driver finds them automatically.

# Rebuilds ./bantam — run `make clean && make` afterwards to restore the
# optimized build. ASANDIR points the gcc driver (-B) at the runtime libs and
# the replacement libasan_preinit.o, and sets an rpath so they load at run time.
