If you want to install the setupsup module or if you want to build it from the scratch, you should read these notes. Installation: Unzip the setupsup.1.0.1.0.zip file to a folder. Make this folder your current directory. In contrast to the installation procedure for the module version 1.08, you don't need to distinguish between perl 5.6 and perl 5.005. The Win32-setupsup.ppd file does this job for you (thanks for the hint to Jenda Krynicky). Type in ppm install win32-setupsup --location=. if you use perl 5.6 or perl 5.005 (type in perl -v to verify your perl version). To verify the installation, type in ppm query. The setupsup module should appear in the list. There is still a version for perl 5.003. You cannot use ppm because perl 5.003 doesn't have a ppm. Use the install.pl instead. Btw, you can install the module with the install.pl for the other perl versions too. But that's not recommended because the module won't be registered in the ppm database. The html help file will be installed only if you use the ppm. You can find the setupsup.html file in the \html\lib\site\setupsup directory. Build the module: You need an installed MSVC++ compiler. I work with MSVC++ version 6 but version 5 should work too. Next, you need the platform sdk. It contains some header files and libraries necessary to build the module. Furthermore, you need the perl source files (in particular, only the header files are necessary). These include header files should be accessible in the \lib\core directory. Set up the compiler environment with vcvars32.bat. Unzip the setupsup.1.0.1.0.zip file to an empty folder. Make this folder to your current directory and load the Makefile in your editor. Change the following settings to your directory names: perldir6xx=c:\programme\perl.615 - directory where perl 5.6 resides perldir5xx=c:\programme\perl.522 - directory where perl 5.005_3 resides perldir3xx=c:\programme\perl.316 - directory where perl 5.003 resides If you only want to build for perl 5.6, you can leave perldir5xx and perldir3xx as they are. platformsdk=c:\programme\microsoft platform sdk must reflect you platform sdk directory. Now you can start the build process. Type in nmake clean nmake or nmake clean cfg=perl.6xx nmake cfg=perl.6xx to build the module for perl 5.6. If you use perl 5.005_03 type in nmake clean cfg=perl.5xx nmake cfg=perl.5xx or nmake clean cfg=perl.3xx nmake cfg=perl.3xx for perl 5.003. If the build was successfully, you'll find the files in the .\inst_dir\perl.xxx directory. To install the module, use nmake install or nmake install cfg=perl.6xx respectively nmake install cfg=perl.5xx or nmake install cfg=perl.3xx
