(转)Net-Google with ActiveState Perl

Net-Google with ActiveState Perl

Installation |

If you want to use the Google APIs via Perl, a search at CPAN wile lead you to Net-Google. However, this distribution seems not to be available for the Active State version of Perl last time I checked (March, 30th, 2004).

You want your ad served 320,000 times a month? and I make it happen.

Luckily, downloading the gzipped tar file and installing it is quite straightforward. But first you need to get a license key from Google.

Getting a Google APIs license key

A license key is required from Google in order to use the Net-Google modules. Visit the site and download the developer's kit. This kit contains useful documentation. Next, create a Google Account to obtain your license key. This key makes it possible to do 1,000 automated queries per day.

After creating the account and confirming it by activating a link you get by email you can request your license key. This key is also send by email. You need this key in the modules build step below and, of course, for using Net-Google in your own Perl programs.

Downloading Net-Google

Select Net-Google from the search result. Click on the link and select the download link from the resulting Net-Google page. This should download a gzipped tar file. When finished downloading, extract the gzipped tar file with, for example, 7-Zip.

Building the Perl modules

In order to build and install the Net-Google modules you need NMake. See for more information on how to obtain NMake.

The following lines are a copy of an installation on a Windows XP system. You need to enter the license key in the NMake test step below.

Note: the latest version of Net-Google available at CPAN has a bug, see: for a quick and easy fix.
