First do "make" and - see if your platform is listed. If so, just do "make xxx", where xxx - is your platform name. The platforms currently supported are: - aix ansi bsd freebsd generic linux macosx mingw posix solaris - - If your platform is not listed, try the closest one or posix, generic, - ansi, in this order. - - See below for customization instructions and for instructions on how - to build with other Windows compilers. - - If you want to check that Lua has been built correctly, do "make test" - after building Lua. Also, have a look at the example programs in test. - -* Installing Lua - -------------- - Once you have built Lua, you may want to install it in an official - place in your system. In this case, do "make install". The official - place and the way to install files are defined in Makefile. You must - have the right permissions to install files. - - If you want to build and install Lua in one step, do "make xxx install", - where xxx is your platform name. - - If you want to install Lua locally, then do "make local". This will - create directories bin, include, lib, man, and install Lua there as - follows: - - bin: lua luac - include: lua.h luaconf.h lualib.h lauxlib.h lua.hpp - lib: liblua.a - man/man1: lua.1 luac.1 - - These are the only directories you need for development. - - There are man pages for lua and luac, in both nroff and html, and a - reference manual in html in doc, some sample code in test, and some - useful stuff in etc. You don't need these directories for development. - - If you want to install Lua locally, but in some other directory, do - "make install INSTALL_TOP=xxx", where xxx is your chosen directory. - - See below for instructions for Windows and other systems. - -* Customization - ------------- - Three things can be customized by editing a file: - - Where and how to install Lua -- edit Makefile. - - How to build Lua -- edit src/Makefile. - - Lua features -- edit src/luaconf.h. - - You don't actually need to edit the Makefiles because you may set the - relevant variables when invoking make. - - On the other hand, if you need to select some Lua features, you'll need - to edit src/luaconf.h. The edited file will be the one installed, and - it will be used by any Lua clients that you build, to ensure consistency. - - We strongly recommend that you enable dynamic loading. This is done - automatically for all platforms listed above that have this feature - (and also Windows). See src/luaconf.h and also src/Makefile. - -* Building Lua on Windows and other systems - ----------------------------------------- - If you're not using the usual Unix tools, then the instructions for - building Lua depend on the compiler you use. You'll need to create - projects (or whatever your compiler uses) for building the library, - the interpreter, and the compiler, as follows: - - library: lapi.c lcode.c ldebug.c ldo.c ldump.c lfunc.c lgc.c llex.c - lmem.c lobject.c lopcodes.c lparser.c lstate.c lstring.c - ltable.c ltm.c lundump.c lvm.c lzio.c - lauxlib.c lbaselib.c ldblib.c liolib.c lmathlib.c loslib.c - ltablib.c lstrlib.c loadlib.c linit.c - - interpreter: library, lua.c - - compiler: library, luac.c print.c - - If you use Visual Studio .NET, you can use etc/luavs.bat in its - "Command Prompt". - - If all you want is to build the Lua interpreter, you may put all .c files - in a single project, except for luac.c and print.c. Or just use etc/all.c. - - To use Lua as a library in your own programs, you'll need to know how to - create and use libraries with your compiler. - - As mentioned above, you may edit luaconf.h to select some features before - building Lua. - -(end of INSTALL) diff --git a/lib/lua/README b/lib/lua/README deleted file mode 100644 index 11b4dff70..000000000 --- a/lib/lua/README +++ /dev/null @@ -1,37 +0,0 @@ -README for Lua 5.1 - -See INSTALL for installation instructions. -See HISTORY for a summary of changes since the last released version. - -* What is Lua? - ------------ - Lua is a powerful, light-weight programming language designed for extending - applications.
