Fixed some diagnostics warnings
Moved examples to tofix because fixing them is besides the point right now.

|
||||
<P>
|
||||
Lua is a powerful, efficient, lightweight, embeddable scripting language
|
||||
developed by a
|
||||
<A HREF="http://www.lua.org/authors.html">team</A>
|
||||
at
|
||||
<A HREF="http://www.puc-rio.br/">PUC-Rio</A>,
|
||||
the Pontifical Catholic University of Rio de Janeiro in Brazil.
|
||||
Lua is
|
||||
<A HREF="#license">free software</A>
|
||||
used in
|
||||
<A HREF="http://www.lua.org/uses.html">many products and projects</A>
|
||||
around the world.
|
||||
|
||||
<P>
|
||||
Lua's
|
||||
<A HREF="http://www.lua.org/">official web site</A>
|
||||
provides complete information
|
||||
about Lua,
|
||||
including
|
||||
an
|
||||
<A HREF="http://www.lua.org/about.html">executive summary</A>
|
||||
and
|

updated

|
||||
especially the
|
||||
<A HREF="http://www.lua.org/manual/5.4/">reference manual</A>,
|
||||
which may differ slightly from the
|
||||
<A HREF="contents.html">local copy</A>
|
||||
distributed in this package.
|
||||
|
||||
<H2><A NAME="install">Installing Lua</A></H2>
|
||||
<P>
|
||||
Lua is distributed in
|
||||
<A HREF="http://www.lua.org/ftp/">source</A>
|
||||
form.
|
||||
You need to build it before using it.
|
||||
Building Lua should be straightforward
|
||||
because
|
||||
Lua is implemented in pure ANSI C and compiles unmodified in all known
|
||||
platforms that have an ANSI C compiler.
|
||||
Lua also compiles unmodified as C++.
|
||||
The instructions given below for building Lua are for Unix-like platforms,
|
||||
such as Linux and Mac OS X.
|
||||
See also
|
||||
<A HREF="#other">instructions for other systems</A>
|
||||
and
|
||||
<A HREF="#customization">customization options</A>.
|
||||
|
||||
<P>
|
||||
If you don't have the time or the inclination to compile Lua yourself,
|
||||
get a binary from
|
||||
<A HREF="http://lua-users.org/wiki/LuaBinaries">LuaBinaries</A>.
|
||||
|
||||
<H3>Building Lua</H3>
|
||||
<P>
|
||||
In most common Unix-like platforms, simply do "<KBD>make</KBD>".
|
||||
Here are the details.
|
||||
|
||||
<OL>
|
||||
<LI>
|
||||
Open a terminal window and move to
|
||||
the top-level directory, which is named <TT>lua-5.4.6</TT>.
|
||||
The <TT>Makefile</TT> there controls both the build process and the installation process.
|
||||
<P>
|
||||
<LI>
|
||||
Do "<KBD>make</KBD>". The <TT>Makefile</TT> will guess your platform and build Lua for it.
|
||||
<P>
|
||||
<LI>
|
||||
If the guess failed, do "<KBD>make help</KBD>" and see if your platform is listed.
|
||||
The platforms currently supported are:
|
||||
<P>
|
||||
<P CLASS="display">
|
||||
guess aix bsd c89 freebsd generic ios linux linux-readline macosx mingw posix solaris
|
||||
</P>
|
||||
<P>
|
||||
If your platform is listed, just do "<KBD>make xxx</KBD>", where xxx
|
||||
is your platform name.
|
||||
<P>
|
||||
If your platform is not listed, try the closest one or posix, generic,
|
||||
c89, in this order.
|
||||
<P>
|
||||
<LI>
|
||||
The compilation takes only a few moments
|
||||
and produces three files in the <TT>src</TT> directory:
|
||||
lua (the interpreter),
|
||||
luac (the compiler),
|
||||
and liblua.a (the library).
|
||||
<P>
|
||||
<LI>
|
||||
To check that Lua has been built correctly, do "<KBD>make test</KBD>"
|
||||
after building Lua. This will run the interpreter and print its version.
|
||||
</OL>
|
||||
<P>
|
||||
If you're running Linux, try "<KBD>make linux-readline</KBD>" to build the interactive Lua interpreter with handy line-editing and history capabilities.
|
||||
If you get compilation errors,
|
||||
make sure you have installed the <TT>readline</TT> development package
|
||||
(which is probably named <TT>libreadline-dev</TT> or <TT>readline-devel</TT>).
|
||||
If you get link errors after that,
|
||||
then try "<KBD>make linux-readline MYLIBS=-ltermcap</KBD>".
|
||||
|
||||
<H3>Installing Lua</H3>
|
||||
<P>
|
||||
Once you have built Lua, you may want to install it in an official
|
||||
place in your system. In this case, do "<KBD>make install</KBD>". The official
|
||||
place and the way to install files are defined in the <TT>Makefile</TT>. You'll
|
||||
probably need the right permissions to install files, and so may need to do "<KBD>sudo make install</KBD>".
|
||||
|
||||
<P>
|
||||
To build and install Lua in one step, do "<KBD>make all install</KBD>",
|
||||
or "<KBD>make xxx install</KBD>",
|
||||
where xxx is your platform name.
|
||||
|
||||
<P>
|
||||
To install Lua locally after building it, do "<KBD>make local</KBD>".
|
||||
This will create a directory <TT>install</TT> with subdirectories
|
||||
<TT>bin</TT>, <TT>include</TT>, <TT>lib</TT>, <TT>man</TT>, <TT>share</TT>,
|
||||
and install Lua as listed below.
|
||||
|
||||
To install Lua locally, but in some other directory, do
|
||||
"<KBD>make install INSTALL_TOP=xxx</KBD>", where xxx is your chosen directory.
|
||||
The installation starts in the <TT>src</TT> and <TT>doc</TT> directories,
|
||||
so take care if <TT>INSTALL_TOP</TT> is not an absolute path.
|
||||
|
||||
<DL CLASS="display">

</DL>
|
||||
|
||||
<P>
|
||||
These are the only directories you need for development.
|
||||
If you only want to run Lua programs,
|
||||
you only need the files in <TT>bin</TT> and <TT>man</TT>.
|
||||
The files in <TT>include</TT> and <TT>lib</TT> are needed for
|
||||
embedding Lua in C or C++ programs.
|
||||
|
||||
<H3><A NAME="customization">Customization</A></H3>
|
||||
<P>
|
||||
Three kinds of things can be customized by editing a file:
|
||||
<UL>
|
||||
<LI> Where and how to install Lua — edit <TT>Makefile</TT>.
|
||||
<LI> How to build Lua — edit <TT>src/Makefile</TT>.
|
||||
<LI> Lua features — edit <TT>src/luaconf.h</TT>.
|
||||
</UL>
|
||||
|
||||
<P>
|
||||
You don't actually need to edit the Makefiles because you may set the
|
||||
relevant variables in the command line when invoking make.
|
||||
Nevertheless, it's probably best to edit and save the Makefiles to
|
||||
record the changes you've made.
|
||||
|
||||
<P>
|
||||
On the other hand, if you need to customize some Lua features, you'll need
|
||||
to edit <TT>src/luaconf.h</TT> before building and installing Lua.
|
||||
The edited file will be the one installed, and
|
||||
it will be used by any Lua clients that you build, to ensure consistency.
|
||||
Further customization is available to experts by editing the Lua sources.
|
||||
|
||||
<H3><A NAME="other">Building Lua on other systems</A></H3>
|
||||
<P>
|
||||
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:
|
||||
|
||||
<DL CLASS="display">
|
||||
<DT>
|
||||
library:
|
||||
<DD>
|
||||
lapi.c lcode.c lctype.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 lcorolib.c ldblib.c liolib.c lmathlib.c loadlib.c loslib.c lstrlib.c ltablib.c lutf8lib.c linit.c
|
||||
<DT>
|
||||
interpreter:
|
||||
<DD>
|
||||
library, lua.c
|
||||
<DT>
|
||||
compiler:
|
||||
<DD>
|
||||
library, luac.c
|
||||
</DL>
|
||||
|
||||
<P>
|
||||
To use Lua as a library in your own programs, you'll need to know how to
|
||||
create and use libraries with your compiler. Moreover, to dynamically load
|
||||
C libraries for Lua, you'll need to know how to create dynamic libraries
|
||||
and you'll need to make sure that the Lua API functions are accessible to
|
||||
those dynamic libraries — but <EM>don't</EM> link the Lua library
|
||||
into each dynamic library. For Unix, we recommend that the Lua library
|
||||
be linked statically into the host program and its symbols exported for
|
||||
dynamic linking; <TT>src/Makefile</TT> does this for the Lua interpreter.
|
||||
For Windows, we recommend that the Lua library be a DLL.
|
||||
In all cases, the compiler luac should be linked statically.
|
||||
|
||||
<P>
|
||||
As mentioned above, you may edit <TT>src/luaconf.h</TT> to customize
|
||||
some features before building Lua.

||||
