Package: texlive-latex-base
Version: 2012.20120611-5
I'm not quite sure which package to report this against, so I start with
the one providing ifpdf.sty.
I am trying to use https://github.com/aginiewicz/createspace.git with
dblatex, and ran into a problem when using xetex as the dblatex backend.
The build fail with "Package createspace Error: no PDF supported engine
detected". I've tracked this down to the fact that \ifpdf return false
with xelatex, even if it is generating a PDF. The following test
document demonstrate the problem:
\documentclass{article}
\usepackage{ifpdf}
\begin{document}
\ifpdf
Using PDF
\else
Not using PDF
\fi
\end{document}
The PDF output is 'Using PDF' with pdflatex, and 'Not using PDF' with
xelatex. I expected it to return 'Using PDF' with both.
Is this a bug in the ifpdf.sty implementation or with xetex?
CC to the createspace style author, to make him aware of this bug
report.

>From the documentation of ifpdf, first sentence:
This package looks for pdfTeX in pdf mode and implements
and sets the switch \ifpdf.
Thus ifpdf behaves absolutely correct.
xetex is not pdftex.
Furthermore, xelatex produces dvi/xdv which is converted to pdf
automatically to pdf using xdvipdfmx, but that doesn't mean that it is
in pdf mode.
You should use ifxetex and ifluatex, too.
Good hints are easily found also via google-that-for-me "ifpdf xetex"
Closing this bug
