Error: ! Incomplete \iffalse

[ssr97jdk]

Hi,

I'm writing a thesis in Latex and I keep getting the following error:

! Incomplete \iffalse; all text was ignored after line 1115

I cannot find any documentation on this error message, and I can find
nothing wrong with the input at line 1115.

Can anyone tell me what this error message means?

Thanks a lot,

Joshua

such things are usually provoked by a macro you call. it could
possibly be occurring in a buggy package, but in this case the error
occurs immediately after the \usepackage command.

>Can anyone tell me what this error message means?

your code took the "false" branch of some \if command, and there
wasn't a corresponding \fi. as you can tell, this is internal stuff,
not latex-ery.

you can easily provoke it: if "iffalse.sty" contains nothing but

\newif\ifbla
\ifbla

then

\usepackage{iffalse}

will provoke:

! Incomplete \iffalse; all text was ignored after line 2.
<inserted text>
\fi

plenty of packages are more than 1115 lines long... ;-)

It might be an instance of the "weird error" described in amsmath.faq
question (2):

(2) Question: I get a weird error that seems to be related to a section
title or a figure caption.

Answer: Check to see if you have used a `fragile' command inside a
`moving' argument (article titles, section titles, figure captions,
table captions, etc.). ... See Section C.1.3 of the LaTeX book.

If you told us the actual contents of line 1115 (and at least a few
preceding lines of context) it would probably be easy for someone to
spot the problem.

Thanks! I have the same problem, and it turns out because an impropriate usage of a package lol.

Best,
