AX_WITH_LUA
AX_PROG_LUA [(MIN-VERSION, [TOO-BIG-VERSION])]
AX_LUA_VERSION (MIN-VERSION, [TOO-BIG-VERSION])
AX_LUA_HEADERS
AX_LUA_HEADERS_VERSION (MIN-VERSION, [TOO-BIG-VERSION])
AX_LUA_LIBS
AX_LUA_READLINE
@end smallexample
@majorheading Description
Detect Lua interpreter, headers and libraries, optionally enforcing a
particular range of versions. If only one version is given, then exactly
this version is required.
AX_WITH_LUA searches for a Lua interpreter and defines LUA if found.
AX_PROG_LUA searches for a Lua interpreter in the given version range,
if any, and defines LUA if found, or stops with an error if not.
AX_LUA_VERSION checks that the version of Lua is at least MIN-VERSION
and less than TOO-BIG-VERSION, if given.
AX_LUA_HEADERS searches for Lua headers and defines HAVE_LUA_H and
HAVE_LUALIB_H if found, and defines LUA_INCLUDE to the preprocessor
flags needed, if any.
AX_LUA_HEADERS_VERSION checks that the Lua headers' version is at least
MIN-VERSION, and less than TOO-BIG-VERSION, if given.
AX_LUA_LIBS searches for Lua libraries and defines LUA_LIB if found.
AX_LUA_READLINE configures Lua to be built with readline support, if
available. This macro requires AX_LIB_READLINE.
Versions are specified as three-digit integers whose first digit is the
major version and last two are the minor version (the same format as
LUA_VERSION_NUM in lua.h); e.g. 501 for Lua 5.1. The revision (e.g. the
"3" in "5.1.3") is ignored.
The following options are added by these macros:
@smallexample
--with-lua-suffix=ARG Lua binaries and library files are
suffixed with ARG.
