3. Installation
Putting it all together.
Follow the instructions for installing the unzip utility of your choosing.
Execute the Cygwin full.exe and follow the installation instructions. If you choose another path than C:\\Program Files\\Cygnus, let the build process know by setting the Cygwin environment variable. On Windows 95/98 setting an environment variable can be done by placing a line in your autoexec.bat. On Windows NT, go to My Computer => Control Panel => System and select the environment tab.
Important: make a temporary directory for Cygwin to use otherwise many commands (most notably bison) will fail. On Windows 95/98, mkdir C:\\TMP. For WindowsNT, mkdir %SystemDrive%\\tmp.
Make a directory and unzip the win32build.zip file into it.
Launch Microsoft Visual C++, and from the menu select Tools => Options. In the dialog, select the directories tab. Sequentially change the dropdown to Executables, Includes, and Library files, and ensure that the Cygwin\\bin, win32build\\include, and win32build\\lib files are in the list below respectively. (To add an entry, select a blank line at the end of the list and begin typing). Typical entries will look like this:
C:\\Program Files\\Cygnus\\cygwin-b20\\H-i586-cygwin32\\bin
C:\\php-win32build\\include
C:\\php-win32build\\lib
