Thanks for the suggestions. I wasn't thinking pkg-config was my problem. The first time I tried to install Cairo I got this message when ExtUtils-PkgConfig was being installed. 'pkg-config' is not recognized as an internal or external command, operable program or batch file. *** *** ExtUtils::PkgConfig requires the pkg-config utility, but it doesn't *** seem to be in your PATH. Is it correctly installed? I run cygwin on my computer so I downloaded the cygwin version of pkg-config and that error went away. Now the problem seems to be that cairo.pc is nowhere on my disk. Package cairo was not found in the pkg-config search path. Perhaps you should add the directory containing `cairo.pc' I already download the binaries and source for cairo from <a href="http://www.gtk.org/download-windows.html">http://www.gtk.org/download-windows.html</a>, but I wasn't able to find a file called cairo.pc. The camelbox distribution seems like it would solve my problem so I might try that. For now, I started using GD::Graph instead of Chart::Clicker (requires Cairo) to create some charts. This all started because I wanted to install Chart::Clicker to generate some charts. Cairo won't install so Chart::Clicker is not an option. <div class="gmail_quote">On Mon, Jun 21, 2010 at 12:45 PM, Tor Lillqvist <<a href="mailto:tml@iki.fi">tml@iki.fi</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div class="im">> pkconfig is a linux only utility. </div>No it isn't. It isn't even a Unix-only utility. You can use pkg-config just fine on Windows, too. It even has a feature that pkg-config lacks on Unix: it automatically re-defines the "prefix" variable read from a .pc file to match the location where the .pc file is found. (I.e. one can unpack a developer package with .pc file anywhere without need to edit the .pc file.) Otherwise it works much like on Unix. And there is even a --msvc-syntax option to turn the -L and -l linker options into the corresponding Microsoft syntax. You can download pkg-config for Windows (and GLib which it requires) from <a href="http://www.gtk.org/download-windows.html" target="_blank">http://www.gtk.org/download-windows.html</a> . --tml </blockquote></div>
