  If the makefiles that come with Fossil do not work for
  you, or for some other reason you want to know how to build
  Fossil manually, then refer to the
  [./makefile.wiki | Fossil Build Process] document which describes
  in detail what the makefiles do behind the scenes.

<li><p>
  The fossil executable is self-contained and stand-alone and usually 
  requires no special libraries or other software to be installed.  However, 
  the "--tk" option to the [/help/diff|diff command] requires that Tcl/Tk
  be installed on the local machine.  You can get Tcl/Tk from 
  [http://www.activestate.com/activetcl|ActiveState].

  To build on older Macs (circa 2002, MacOS 10.2) edit the Makefile
  generated by configure to add the following lines:
  <blockquote><pre>
  TCC += -DSQLITE_WITHOUT_ZONEMALLOC
  TCC += -DWITHOUT_ICONV
  TCC += -Dsocketlen_t=int
