# LUA_VERSION currently installed version of Lua

# LUA_MODULES list of Lua modules to build/installi
|
|
# LUA_DPLIBS shared library dependencies as per LIBDPLIBS

# HAVE_LUAC if defined, .lua source files will be compiled with ${LUAC}
|
|
# and installed as precompiled chunks for faster loading. Note
|
|
# that the luac file format is not yet standardised and may be
|
|
# subject to change.
|
|
#
|
|
# LUAC the luac compiler (by default: /usr/bin/luac)
|
|
#
|
|
#
|
|
# Notes:
|
|
#
|
|
# currently make(depend) and make(tags) do not support .lua sources; We
|
|
# add Lua sources to DPSRCS when HAVE_LUAC is defined and other language
|
|
# sources to SRCS for <bsd.dep.mk>.
|
|
#
|
|
# other language support for other than C is incomplete
|
|
#
|
|
# C language sources are passed though lint, when MKLINT != "no"
|
|
#
|
|
# The Lua binary searches /usr/share/lua/5.1/ at this time and we could
|
|
# install .lua modules there which would mean slightly less duplication
|
|
# in compat builds. However, MKSHARE=no would prevent such modules from
|
|
# being installed so we just install everything under /usr/lib/lua/5.1/
