4 LuaGRAPH is a binding to the graphviz library.
6 LuaGRAPH requires the graphviz library version 2.26 or later, which
7 can be downloaded from:
9 [http://www.graphviz.org/](http://www.graphviz.org/)
12 You must have Lua version 5.1, 5.2 or 5.3. Lua can be downloaded
15 [http://www.tecgraf.puc-rio.br/lua/](http://www.tecgraf.puc-rio.br/lua/)
20 Documentation of LuaGRAPH comes with the LuaGRAPH distribution. I recommend also to read the graphviz documentation, which can be found here:
22 [http://www.graphviz.org/Documentation.php](http://www.graphviz.org/Documentation.php)
28 See the license agreement in the file LICENSE.
32 LuaGRAPH can be downloaded from github at
34 [https://github.com/hleuwer/luagraph](https://github.com/hleuwer/luagraph)
36 or install with luarocks. See below under "Installation".
41 Before building LuaGRAPH you have to adopt the config file by
42 adjusting various constants to the installed Lua and Graphviz version.
46 Newest version is LuaGRAPH 2.0 now supports the `cgraph´ library and all
47 Lua versions from Lua 5.1 to Lua 5.3. Lua 5.0 is no longer supported.
48 It has been tested on MacOS Sierra version 10.12.13, Linux Debian and
49 Windows 10 running as guest in a Virtual Box virtual machine under MacOS.
51 Under Windows luarocks has only been tested with Lua 5.1 using the
52 LuaForWindows installation.
57 **Install via Luarocks (MacOS and Linux only)**
59 Simply type the following:
61 $ sudo luarocks GRAPHVIZ_DIR=/opt/local install luagraph
63 You may have to change the value for the GRAPHVIZ_DIR variable to ensure
64 that luarocks finds your GRAPHVIZ installation. On MacOS it is typically
65 installed in /opt/local.
67 **Manual Installation under MacOS or Linux**
69 In order to build LuaGRAPH on a Linux, MacOS or Cygwin/Mingw based
72 1. Make sure you have Lua 5.1 to 5.3.
73 The file test.lua in the test subdirectory uses lualogging which
74 can be installed via Luarocks at http://www.luarocks.org.
76 2. With graphviz version 2.12 you might have to use the `ltdl' library
77 that comes with graphviz in order to have the rendering plugins to
78 work properly. Version 2.40 is currently the last graphviz version
81 3. LuaGRAPH comes with a makefile and a simple config file to adopt
82 the make process to your target system.
84 4. Adopt build configuration to your platform by editing the file
85 config according to you needs.
87 5. Compile the package
92 If make succeeds you get:
94 * a Lua extension library "graph.so.x.0" in the src sub-directory.
95 * a copy "core.so" of the same Lua extension library in ./graph
97 6. Type "make install" as user root in order to install all relevant
98 files in standard places. The directory /usr/local is the default
101 **Manual Build and Installation under Windows**
103 In order to build LuaGRAPH on Windows, use the Visual Studio 2008
104 project file that comes with source code. Load the project and build
105 a Release version inside the Visual Sudio IDE. To make the luagraph
106 module available copy the file Release/luagraph-2.0.0-2.dll into
107 graph/core.dll. Sorry for this inconvenience, which I may remove
108 once I have a really large amount of time.
