Last night, I wrote about how I could not easily add the barcode functionality to the build because it was not guaranteed that the library would be on every computer compiling it.

I did two main things:

1. Added ENABLE() and HAVE() macros. Inspired by WebKit’s, here. This allows enabling and disabling the capabilities through a configuration header file (now located in config/config.h).
2. Added a simple generate-config script. I know there are existing tools for this — I think GNU’s Autoconf does it — but I didn’t have time to learn something new, and I also didn’t want to invest in such complexity for a system which would not work in Windows. The Windows script is a command file; the Mac one is a shell script.

I like how the scripts have no prerequisites on Mac and Windows. Unfortunately, I will probably have to rewrite them later in a consolidated form, so that I only have on script; at this point, it will likely cease to have no prerequisites.

So, how do compile with support for the barcode? On Mac, you have to put the libUSPS4CB.dylib in /usr/local/lib/. On Windows, you have to put in in your WINDOWS folder. And that’s it.
