INSTALL for Lua 5.1
* Building Lua ------------ Lua is built in the src directory, but the build process can be controlled from the top-level Makefile.
Building Lua on Unix systems should be very easy. 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.
