I wanted to use BibLateX with IEEE style, because of urldate. The problem is, I'm getting error:

! LaTeX Error: Missing \begin{document}.

I'm using pdftex and bibtex for compilation.

I'm completely new to biblatex, so I wrote this code according to the answers in this question.


I'm using TexMaker - now with biber option for compilation according to this question.

My code

  • Welcome to TeX.SX! What is inside your .bib file? Normally, this should work

  • You use the backend=biber option, but compile with bibtex

    I suppose the code that is posted compiles for you as it compiles for me. So your problem comes from something else and it may be hard to detect what is the problem. I suspect it comes from mistyping some part of the preamble that results in the preamble containing something that should be there. A simple dot inadvertently typed before \begin{document} leads to such an error. So the best you have to do is commenting package loading in the preamble,and uncommenting gradually until the problem happens again. Then you should be able to llocalise the problem.

    You should show more of the error message - latex tells you the line and the offending input. May 14, 2015 at 21:17
