| [28] | 1 | INSTALL for Lua 5.1 |
|---|
| 2 | |
|---|
| 3 | * Building Lua |
|---|
| 4 | ------------ |
|---|
| 5 | Lua is built in the src directory, but the build process can be |
|---|
| 6 | controlled from the top-level Makefile. |
|---|
| 7 | |
|---|
| 8 | Building Lua on Unix systems should be very easy. First do "make" and |
|---|
| 9 | see if your platform is listed. If so, just do "make xxx", where xxx |
|---|
| 10 | is your platform name. The platforms currently supported are: |
|---|
| 11 | aix ansi bsd freebsd generic linux macosx mingw posix solaris |
|---|
| 12 | |
|---|
| 13 | If your platform is not listed, try the closest one or posix, generic, |
|---|
| 14 | ansi, in this order. |
|---|
| 15 | |
|---|
| 16 | See below for customization instructions and for instructions on how |
|---|
| 17 | to build with other Windows compilers. |
|---|
| 18 | |
|---|
| 19 | If you want to check that Lua has been built correctly, do "make test" |
|---|
| 20 | after building Lua. Also, have a look at the example programs in test. |
|---|
| 21 | |
|---|
| 22 | * Installing Lua |
|---|
| 23 | -------------- |
|---|
| 24 | Once you have built Lua, you may want to install it in an official |
|---|
| 25 | place in your system. In this case, do "make install". The official |
|---|
| 26 | place and the way to install files are defined in Makefile. You must |
|---|
| 27 | have the right permissions to install files. |
|---|
| 28 | |
|---|
| 29 | If you want to build and install Lua in one step, do "make xxx install", |
|---|
| 30 | where xxx is your platform name. |
|---|
| 31 | |
|---|
| 32 | If you want to install Lua locally, then do "make local". This will |
|---|
| 33 | create directories bin, include, lib, man, and install Lua there as |
|---|
| 34 | follows: |
|---|
| 35 | |
|---|
| 36 | bin: lua5.1 luac5.1 |
|---|
| 37 | include: lua.h luaconf.h lualib.h lauxlib.h lua.hpp |
|---|
| 38 | lib: liblua5.1.a |
|---|
| 39 | man/man1: lua5.1.1 luac5.1.1 |
|---|
| 40 | |
|---|
| 41 | These are the only directories you need for development. |
|---|
| 42 | |
|---|
| 43 | There are man pages for lua and luac, in both nroff and html, and a |
|---|
| 44 | reference manual in html in doc, some sample code in test, and some |
|---|
| 45 | useful stuff in etc. You don't need these directories for development. |
|---|
| 46 | |
|---|
| 47 | If you want to install Lua locally, but in some other directory, do |
|---|
| 48 | "make install INSTALL_TOP=xxx", where xxx is your chosen directory. |
|---|
| 49 | |
|---|
| 50 | See below for instructions for Windows and other systems. |
|---|
| 51 | |
|---|
| 52 | * Customization |
|---|
| 53 | ------------- |
|---|
| 54 | Three things can be customized by editing a file: |
|---|
| 55 | - Where and how to install Lua -- edit Makefile. |
|---|
| 56 | - How to build Lua -- edit src/Makefile. |
|---|
| 57 | - Lua features -- edit src/luaconf.h. |
|---|
| 58 | |
|---|
| 59 | You don't actually need to edit the Makefiles because you may set the |
|---|
| 60 | relevant variables when invoking make. |
|---|
| 61 | |
|---|
| 62 | On the other hand, if you need to select some Lua features, you'll need |
|---|
| 63 | to edit src/luaconf.h. The edited file will be the one installed, and |
|---|
| 64 | it will be used by any Lua clients that you build, to ensure consistency. |
|---|
| 65 | |
|---|
| 66 | We strongly recommend that you enable dynamic loading. This is done |
|---|
| 67 | automatically for all platforms listed above that have this feature |
|---|
| 68 | (and also Windows). See src/luaconf.h and also src/Makefile. |
|---|
| 69 | |
|---|
| 70 | * Building Lua on Windows and other systems |
|---|
| 71 | ----------------------------------------- |
|---|
| 72 | If you're not using the usual Unix tools, then the instructions for |
|---|
| 73 | building Lua depend on the compiler you use. You'll need to create |
|---|
| 74 | projects (or whatever your compiler uses) for building the library, |
|---|
| 75 | the interpreter, and the compiler, as follows: |
|---|
| 76 | |
|---|
| 77 | library: lapi.c lcode.c ldebug.c ldo.c ldump.c lfunc.c lgc.c llex.c |
|---|
| 78 | lmem.c lobject.c lopcodes.c lparser.c lstate.c lstring.c |
|---|
| 79 | ltable.c ltm.c lundump.c lvm.c lzio.c |
|---|
| 80 | lauxlib.c lbaselib.c ldblib.c liolib.c lmathlib.c loslib.c |
|---|
| 81 | ltablib.c lstrlib.c loadlib.c linit.c |
|---|
| 82 | |
|---|
| 83 | interpreter: library, lua.c |
|---|
| 84 | |
|---|
| 85 | compiler: library, luac.c print.c |
|---|
| 86 | |
|---|
| 87 | If you use Visual Studio .NET, you can use etc/luavs.bat in its |
|---|
| 88 | "Command Prompt". |
|---|
| 89 | |
|---|
| 90 | If all you want is to build the Lua interpreter, you may put all .c files |
|---|
| 91 | in a single project, except for luac.c and print.c. Or just use etc/all.c. |
|---|
| 92 | |
|---|
| 93 | To use Lua as a library in your own programs, you'll need to know how to |
|---|
| 94 | create and use libraries with your compiler. |
|---|
| 95 | |
|---|
| 96 | As mentioned above, you may edit luaconf.h to select some features before |
|---|
| 97 | building Lua. |
|---|
| 98 | |
|---|
| 99 | (end of INSTALL) |
