LuaJIT is only distributed as a source package. This page explains
|
||
|
|
how to build and install LuaJIT with different operating systems
|
||
|
|
and C compilers.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
For the impatient (on POSIX systems):
|
||
|
|
</p>
|
||
|
|
<pre class="code">
|
||
|
|
make && sudo make install
|
||
|
|
</pre>
|
||
|
|
<p>
|
||
|
|
LuaJIT currently builds out-of-the box on all popular x86 systems
|
||
|
|
(Linux, Windows, OSX etc.). It builds and runs fine as a 32 bit
|
||
|
|
application under x64-based systems, too.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h2>Configuring LuaJIT</h2>
|
||
|
|
<p>
|
||
|
|
The standard configuration should work fine for most installations.
|
||
|
|
Usually there is no need to tweak the settings, except when you want to
|
||
|
|
install to a non-standard path. The following three files hold all
|
||
|
|
user-configurable settings:
|
||
|
|
</p>
|
||
|
|
<ul>
|
||
|
|
<li><tt>src/luaconf.h</tt> sets some configuration variables, in
|
||
|
|
particular the default paths for loading modules.</li>
|
||
|
|
<li><tt>Makefile</tt> has settings for installing LuaJIT (POSIX
|
||
|
|
only).</li>
|
||
|
|
<li><tt>src/Makefile</tt> has settings for compiling LuaJIT under POSIX,
|
||
|
|
MinGW and Cygwin.</li>
|
||
|
|
<li><tt>src/msvcbuild.bat</tt> has settings for compiling LuaJIT with
|
||
|
|
MSVC.</li>
|
||
|
|
</ul>
|
||
|
|
<p>
|
||
|
|
Please read the instructions given in these files, before changing
|
||
|
|
any settings.
|
||
|

|
<h3>Prerequisites</h3>
|
||
|
|
<p>
|
||
|
|
Depending on your distribution, you may need to install a package for
|
||
|
|
GCC (GCC 3.4 or later required), the development headers and/or a
|
||
|
|
complete SDK.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
E.g. on a current Debian/Ubuntu, install <tt>libc6-dev</tt>
|
||
|
|
with the package manager. Currently LuaJIT only builds as a 32 bit
|
||
|
|
application, so you actually need to install <tt>libc6-dev-i386</tt>
|
||
|
|
when building on an x64 OS.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
Download the current source package (pick the .tar.gz), if you haven't
|
||
|
|
already done so. Move it to a directory of your choice, open a
|
||
|
|
terminal window and change to this directory. Now unpack the archive
|
||
|
|
and change to the newly created directory:
|
||
|
|
</p>
|
||
|
|
<pre class="code">
|
||
|
|
tar zxf LuaJIT-2.0.0-beta1.tar.gz
|
||
|
|
cd LuaJIT-2.0.0-beta1
|
||
|
|
</pre>
|
||
|
|
<h3>Building LuaJIT</h3>
|
||
|
|
<p>
|
||
|
|
The supplied Makefiles try to auto-detect the settings needed for your
|
||
|
|
operating system and your compiler. They need to be run with GNU Make,
|
||
|
|
which is probably the default on your system, anyway. Simply run:
|
||
|
|
</p>
|
||
|
|
<pre class="code">
|
||
|
|
make
|
||
|
|
</pre>
|
||
|
|
<h3>Installing LuaJIT</h3>
|
||
|
|
<p>
|
||
|
|
The top-level Makefile installs LuaJIT by default under
|
||
|
|
<tt>/usr/local</tt>, i.e. the executable ends up in
|
||
|
|
<tt>/usr/local/bin</tt> and so on. You need to have root privileges
|
||
|
|
to write to this path. So, assuming sudo is installed on your system,
|
||
|
|
run the following command and enter your sudo password:
|
||
|
|
</p>
|
||
|
|
<pre class="code">
|
||
|
|
sudo make install
|
||
|
|
</pre>
|
||
|
|
<p>
|
||
|
|
Otherwise specify the directory prefix as an absolute path, e.g.:
|
||
|
|
</p>
|
||
|
|
<pre class="code">
|
||
|
|
sudo make install PREFIX=/opt/lj2
|
||
|
|
</pre>
|
||
|
|
<p>
|
||
|
|
But note that the installation prefix and the prefix for the module paths
|
||
|
|
(configured in <tt>src/luaconf.h</tt>) must match.
|
||
|
|
</p>
|
||
|
|
<p style="color: #c00000;">
|
||
|
|
Note: to avoid overwriting a previous version, the beta test releases
|
||
|
|
only install the LuaJIT executable under the versioned name (i.e.
|
||
|
|
<tt>luajit-2.0.0-beta1</tt>). You probably want to create a symlink
|
||
|
|
for convenience, with a command like this:
|
||
|
|
</p>
|
||
|
|
<pre class="code" style="color: #c00000;">
|
||
|
|
sudo ln -sf luajit-2.0.0-beta1 /usr/local/bin/luajit
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<h2 id="windows">Windows Systems</h2>
|
||
|
|
<h3>Prerequisites</h3>
|
||
|
|
<p>
|
||
|
|
Either install one of the open source SDKs
|
||
|
|
(<a href="http://mingw.org/"><span class="ext">»</span> MinGW</a> or
|
||
|
|
<a href="http://www.cygwin.com/"><span class="ext">»</span> Cygwin</a>) which come with modified
|
||
|
|
versions of GCC plus the required development headers.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
Or install Microsoft's Visual C++ (MSVC) — the freely downloadable
|
||
|
|
<a href="http://www.microsoft.com/Express/VC/"><span class="ext">»</span> Express Edition</a>
|
||
|
|
works just fine.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
Next, download the source package and unpack it using an archive manager
|
||
|
|
(e.g. the Windows Explorer) to a directory of your choice.
|
||
|
|
</p>
|
||
|
|
<h3>Building with MSVC</h3>
|
||
|
|
<p>
|
||
|
|
Open a "Visual Studio .NET Command Prompt" and <tt>cd</tt> to the
|
||
|
|
directory where you've unpacked the sources. Then run this command:
|
||
|
|
</p>
|
||
|
|
<pre class="code">
|
||
|
|
cd src
|
||
|
|
msvcbuild
|
||
|
|
</pre>
|
||
|
|
<p>
|
||
|
|
Then follow the installation instructions below.
|
||
|
|
</p>
|
||
|
|
<h3>Building with MinGW or Cygwin</h3>
|
||
|
|
<p>
|
||
|
|
Open a command prompt window and make sure the MinGW or Cygwin programs
|
||
|
|
are in your path. Then <tt>cd</tt> to the directory where
|
||
|
|
you've unpacked the sources and run this command for MinGW:
|
||
|
|
</p>
|
||
|
|
<pre class="code">
|
||
|
|
cd src
|
||
|
|
mingw32-make
|
||
|
|
</pre>
|
||
|
|
<p>
|
||
|
|
Or this command for Cygwin:
|
||
|
|
</p>
|
||
|
|
<pre class="code">
|
||
|
|
cd src
|
||
|
|
make
|
||
|
|
</pre>
|
||
|
|
<p>
|
||
|
|
Then follow the installation instructions below.
|
||
|
|
</p>
|
||
|
|
<h3>Installing LuaJIT</h3>
|
||
|
|
<p>
|
||
|
|
Copy <tt>luajit.exe</tt> and <tt>lua51.dll</tt>
|
||
|
|
to a newly created directory (any location is ok). Add <tt>lua</tt>
|
||
|
|
and <tt>lua\jit</tt> directories below it and copy all Lua files
|
||
|
|
from the <tt>lib</tt> directory of the distribution to the latter directory.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
There are no hardcoded
|
||
|
|
absolute path names — all modules are loaded relative to the
|
||
|
|
directory where <tt>luajit.exe</tt> is installed
|
||
|
|
(see <tt>src/luaconf.h</tt>).
|
||
