Parallel C4.5: Installation

1. Uncompress the source code.
   Place pc4.5.tar.gz in your home directory and issue the following commands:
   

   gunzip pc4.5.tar.gz

   and then
   

   tar xvf pc4.5.tar

2. Compile PLinda.
   Compiling PLinda requires GNU C++ (g++) version 2.6.3 or higher and GNU make. They can be ftp'ed from http://www.ai.mit.edu/!info/dir/!!first.
   First,
   

   cd plinda/plinda-2.6b

   If you are compiling on a SunOS machine, issue this command:

   make -f SunOS

   For Solaris or Linux, substitute SunOS with Solaris or Linux. I will use SunOS as an example in the following steps.
3. Install PLinda.
   If step 2 goes well, issue this command:

   make install -f SunOS

   Now you have compiled and installed PLinda.
4. Set up PLinda environment.
   Edit ~/plinda/bin/sunos/plc (a Perl script) and change the path of perl (unless it is /usr/bin/perl). You can find out where perl is by "whereis perl" or "which perl".
5. Merge C4.5 into PC4.5.
   Suppose your C4.5 directory is ~/C4.5. Link C4.5 source code with PC4.5 by issuing this command:

   ln -s ~/C4.5/Src/* ~/plinda/code/pc4.5

   Ignore any warning.
6. Compile PC4.5.
   First,

   cd ~/plinda/code/pc4.5

   Then compile PC4.5 by issuing this command:

   make pc4.5 -f SunOS
