Compiling Factor on the Intel Mac

To compile Factor for Mac you will need:

• Installation DVDs that came with your Mac (for X11)
  
• darwin-ports

1. Run the installation disk that came with your Mac in order to install X11. Since Apple does not offer X11 as a download for OS X 10.4 for Intel computers, you have to install from the DVD.
2. Download the darcs binary and place it in /usr/local/bin
   
3. Open terminal (Finder->Applications->Utilities->Terminal) and go to your home directory. To get the Factor source code, run:
   

   darcs get http://factorcode.org/repos

4. To compile, move into the directory darcs created with cd repos/Factor and run the command make macosx-x86
5. Download the boot image at http://factorcode.org/images/latest/boot.image.pentium4
   
6. ./f boot.image.pentium4
7. make macosx.app
8. (Optional) Create a shell script to start Factor in your terminal window. I called mine go.

   #!/bin/sh
   DIR=~/repos/Factor/Factor.app/Contents
   $DIR/MacOS/Factor $@
   
   Save the file and run chmod a+x go

9. (Optional) You can instead run open Factor.app and use Console.app to view runtime output.
   

To start the UI, run ./go or open Factor.app; run ./f to start Factor in the shell. If you run Factor in the terminal, I suggest using rlwrap, which adds a history buffer

Now you can code anything!
