Building gdchart.so in Unix systems

To build the Unix-flavored gdchart.so shared library needed for the Zope's ZGDChart product, please follow these instructions. (If you are lucky, this maybe the only README file that you'll need to read.)

1. Unzip, untar the enclosed gdchart-py-0.42b.tgz file. This will generate the gdchart0.94b folder inside the ZGDChart's product folder.
   
   
2. Go into the gd-1.8.1 subfolder, enter
   

         make

   If there are problems, you may need to modify the Makefile yourself.
   
   
3. Come back to the original folder (gdchart0.94b), edit the makepy.linux (or makepy.solaris) file. Make sure that the lines

         CPPFLAGS = -I. -I/usr/local/include/python1.5
         ...
         LDFLAGS = -Lgd-1.8.1 -L/usr/lib

   correspond to your system's configuration for the Python include directory and the jpeg-lib, libpng and zlib libraries. In some systems, the Python include directory might be located in /usr/include/python1.5.
   
   After making sure, enter:

         make -f makepy.linux

   or, for Solaris systems:

         make -f makepy.solaris

   This will generate the gdchart.so shared library, which you can then copy to your lib/python/Products/ZGDChart folder inside your Zope installation folder.
