Chapter 1

Build

Now that you've unpacked the module, you need to build it. Enter the directory 

created by unpacking the compressed module file. It's usually named the same as 

the compressed file but with the .tar.gz or .zip ending removed. 

If the module has no installation instructions, look for a file called Makefile.PL.

If it exists, enter the following commands:

$ perl Makefile.PL

$ make

These commands will fail if you're missing a prerequisite module. A prerequisite 

module is a module that is needed by the module you're installing. If the module 

has unsatisfied prerequisites, you'll need to find the required module or modules 

and install them before returning to installing this module.

These commands may also fail if you're using a Microsoft Windows system, 

because few Windows systems have the make utility installed. You may need to 

install the CygWin toolkit I mentioned in the  Decompression  section, which 

offers the GNU make utility as an optional component. Alternately, you may have a 

program called nmake

 or dmake, which can function as make.

Regrettably, there are some modules on CPAN that don't use the standard 

module packaging system. Sometimes these modules will include an INSTALL file 

containing installation instructions, or installation instructions will be contained 

in the README file.

Test

Many CPAN modules come with tests to verify that the module is working properly 

on your system. The standard way to run module tests is with this command:

$ make test
