$ ./configure --with-lua=''lua_dir''
You'll get the follwing automake macros @LUA_INCLUDES@ and @LUA_LIBS@
and the following #defines in config.h
/* Define to 1 if you have the <lualib.h> header file. */ #define HAVE_LUALIB_H 1 /* Define to use Lua 5.1 */ #define HAVE_LUA_5_1 1 /* Define to 1 if you have the <lua.h> header file. */ #define HAVE_LUA_H 1
These are the two parts to add
This one for acinclude.m4
If --with-lua is not specified, the script should attempt to get the C flags and link flags from pkg-config. --JohnBelmonte
