Texmaker and TeXstudio ⇒ Biblatex Referencing

[flin]

Hi folks,
i'm trying to reference my paper(harvard style), but the code I've been using isn't working for me, and I don't know why.
Whenever I'm trying to do the "quick build" run on my TexMaker, it'll tell me that it can't find 'etoolbox.sty', and that my pdf will display question marks.

I don't understand why I'll need the 'etoolbox.sty'. Help! this is driving me nuts. Am I doing something wrong here? Do I need an auxiliary file? I'm seriously confused. Would appreciate an ASAP reply.
Cheers
p.s. I'm using miktex

Hi,

etoolbox is a package like bilatex or mathtools and needed by many packages. You can install it with your MikTeX package manager.
Furthermore, please use the code button to highlight your code.

LaTeX creates some files while compiling your project, and all are needed. Do not delete them. If you want to know, what's in there, open them with an editor or try a short google search.

Hi flin,

Welcome to the LaTeX community!

As Johannes said: etoolbox is used by lots of packages as it provides a range of handy tools for LaTeX programming. In particular biblatex uses etoolbox a lot. Both packages happen to be from the same author, Philipp Lehman, although biblatex is maintained by other people nowadays.

You do not need an extra auxiliary file but should install the missing package via the package manager. Auxiliary files are files created during compilation, most notably the one with the extension aux. They are needed to save data that can be used on a subsequent compilation run, such as labels and references. Usually you do not need to care about them at all. Most can also be deleted without harm but that would ruin references and similar stuff and you need to start a whole compilation circle again. The most interesting file is the log file as it contains information about the compilation, about included files and packages and their versions, it contains all errors and warnings produced during the compilation.
