21 * Compiling the Factor VM
23 The Factor runtime is written in GNU C99, and is built with GNU make and
26 Factor supports various platforms. For an up-to-date list, see
27 <http://factorcode.org/getfactor.fhtml>.
29 Factor requires gcc 3.4 or later.
31 On x86, Factor /will not/ build using gcc 3.3 or earlier.
33 If you are using gcc 4.3, you might get an unusable Factor binary unless
34 you add 'SITE_CFLAGS=-fno-forward-propagate' to the command-line
37 Run 'make' ('gmake' on *BSD) with no parameters to build the Factor VM.
39 Compilation will yield an executable named 'factor' on Unix,
40 'factor.exe' on Windows XP/Vista, and 'factor-ce.exe' on Windows CE.
42 * Libraries needed for compilation
44 For X11 support, you need recent development libraries for libc,
45 Freetype, X11, OpenGL and GLUT. On a Debian-derived Linux distribution
46 (like Ubuntu), you can use the following line to grab everything:
48 sudo apt-get install libc6-dev libfreetype6-dev libx11-dev glutg3-dev
50 * Bootstrapping the Factor image
52 Once you have compiled the Factor runtime, you must bootstrap the Factor
53 system using the image that corresponds to your CPU architecture.
55 Boot images can be obtained from <http://factorcode.org/images/latest/>.
57 Once you download the right image, bootstrap Factor with the
58 following command line:
60 ./factor -i=boot.<cpu>.image
62 Bootstrap can take a while, depending on your system. When the process
63 completes, a 'factor.image' file will be generated. Note that this image
64 is both CPU and OS-specific, so in general cannot be shared between
67 * Running Factor on Unix with X11
69 On Unix, Factor can either run a graphical user interface using X11, or
72 If your DISPLAY environment variable is set, the UI will start
77 To run an interactive terminal listener:
79 ./factor -run=listener
81 If you're inside a terminal session, you can start the UI with one of
82 the following two commands:
87 The latter keeps the terminal listener running.
89 * Running Factor on Mac OS X - Cocoa UI
91 On Mac OS X, a Cocoa UI is available in addition to the terminal
94 The 'factor' executable runs the terminal listener:
98 The 'Factor.app' bundle runs the Cocoa UI. Note that this is not a
99 self-contained bundle, it must be run from the same directory which
100 contains factor.image and the library sources.
102 * Running Factor on Mac OS X - X11 UI
104 The X11 UI is also available on Mac OS X, however its use is not
105 recommended since it does not integrate with the host OS.
107 When compiling Factor, pass the X11=1 parameter:
111 Then bootstrap with the following switches:
113 ./factor -i=boot.<cpu>.image -ui-backend=x11
115 Now if $DISPLAY is set, running ./factor will start the UI.
117 * Running Factor on Windows XP/Vista
119 If you did not download the binary package, you can bootstrap Factor in
122 factor.exe -i=boot.<cpu>.image
124 Once bootstrapped, double-clicking factor.exe starts the Factor UI.
126 To run the listener in the command prompt:
128 factor.exe -run=listener
132 The Factor FAQ is available at <http://factorcode.org/faq.fhtml>.
136 Factor supports a number of command line switches. To read command line
137 usage documentation, enter the following in the UI listener:
141 * Source organization
143 The Factor source tree is organized as follows:
145 build-support/ - scripts used for compiling Factor
146 vm/ - sources for the Factor VM, written in C
147 core/ - Factor core library
148 basis/ - Factor basis library, compiler, tools
149 extra/ - more libraries and applications
150 fonts/ - TrueType fonts used by UI
151 misc/ - editor modes, icons, etc
152 unmaintained/ - unmaintained contributions, please help!
156 The Factor homepage is located at <http://factorcode.org/>.
158 Factor developers meet in the #concatenative channel on the
159 irc.freenode.net server. Drop by if you want to discuss anything related
160 to Factor or language design in general.
