D-Bus C API Compilation Problems

Well, ignore my last post. At this point, I essentially have nothing done for my project, since I cannot get anything to compile. I figure it would be essentially impossible to learn Python well enough in time to get my 0.1 release coded, so I started looking into the C API for DBus. However, I cannot get it to compile. My first hassle was getting the compiler to find the dbus.h file, which I was able to solve with the proper flags. Now, when I try to compile, the compiler cannot find required functions. My code and the compilation errors are posted at http://pastebin.ca/1219504 If i can't get this to compile, then I'm screwed for Friday's due date. Does anybody have any suggestions on how to get this to work?

Extensions, d-bus, and Python, oh my!

So far, my project seems to be going fairly well. Firefox extensions use javascript as their primary language, which unfortunately does not have a wrapper for d-bus, which I need to communicate with NetworkManager. Fortunately, Python has these wrappers, and I can use Python classes in the Javascript using XPCOM. What this means, is that I can link Python and Javascript together: use Python for the lower-level stuff, the actual communication, and pass ifno back to the javascript, which can then talk with Firefox, and do the actual login itself. While I don't know python yet, it looks like a simplistic enough language, and will be the first I've learned that is not C-style. This should be an intereting experience, and if nothing else, I can add Python to my resume.

Scouring the Source

For the Mozilla Source Code Reading Lab, I have decided to look into how the browser closes a tab. What I have found, is that from one of many places (I cannot tell exactly where), the function "removeTab" is called, with "aTab" passed in. This then calls "this._endRemoveTab" passing in theaTab, and true. As near as I can tell, this line is the one that actually removes the tab, however, while the mTabContainer is of type tabcontainer, I am unable to find the definition of the tabcontainer to follow this further
Experiences Building Firefox

So, for the OSD600 lab, I downloaded and built Firefox (Minefield, to be more accurate, otherwise Humphrey's gonna kill me...). Seeing as when I first got into Linux, we didn't have such fancy things as "Package managers" and had to compile everything from source... I jest, really, they were there, but I had just never heard of them, nor were they as good as they are now. but anyways, I used to always build things from source, including the Linux kernel itself, and so this really wasn't all that new of an experience. What I did learn, though, was a bit about Mercurial, and autoconf. Wanting to get the latest version, I used mercurial to clone the Mozilla repository to my local machine, and compile it from there. When this was done, I had the problem of there not being the configure script I was expecting. Since it was not an official release, it didn't come with one, so I would have to generate one myself. This took me a little while to figure out, until I came across something in the build documentation (don't ask where, I couldn't find it when I went looking for it) telling me that I needed to use autoconf2.13. After learning that the newer version of Autoconf I had installed wouldn't work, and I got the 2.13 release, I was finally able to build the newest Minefield. I've noticed that my build times were substantially less than those from people using similar systems, but I think this is because I had no particular desire to run the tests the make scripts run, so I disabled these is my .mozconfig file.At some point, I should try building this thing on Windows, but that would require me to actually use the OS for somehting more than gaming, which I have no real desire to do...
