AX_WITH_LUA
AX_LUA_VERSION (MIN-VERSION, [TOO-BIG-VERSION])
AX_LUA_HEADERS
AX_LUA_LIBS
AX_LUA_LIB_VERSION (MIN-VERSION, [TOO-BIG-VERSION])
Detect Lua interpreter, headers and libraries, optionally enforcing a particular range of versions.
AX_WITH_LUA searches for Lua interpreter and defines LUA if found.
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_LIBS searches for Lua libraries and defines LUA_LIB if found.
AX_LUA_LIB_VERSION checks that the Lua libraries' version is at least MIN-VERSION, and less than TOO-BIG-VERSION, if given.
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:
--with-lua-prefix=DIR Lua files are in DIR. --with-lua-suffix=ARG Lua binaries and library files are suffixed with ARG. --with-lua-includes=DIR Lua include files are in DIR. --with-lua-libraries=DIR Lua library files are in DIR.
