Math & Science ⇒ Problem with (both) siunitx and xfrac

[cbkschroeder]

Hello,

Thanks for reading my post.

I have several documents which, as of today, don't compile; they complied fine before. I have MikTeX 2.8 and have run my package updater today.

One example:

Code: Select all

\documentclass{article}

\usepackage{xfrac}

\begin{document}
\end{document}

This produces output as shown in "test 01.log".

A second example is:

Code: Select all

\documentclass{article}

\usepackage{siunitx}

\begin{document}
\num{1}
\end{document}

This produces output as shown in "test 02.log".

I am assuming the problem with siunitx exists because there may be a problem with xfrac. Otherwise, as simple as it seems, perhaps the problem is with me! Am I missing something?

Thanks for any feedback or help!

I am using an up-to-date version of the TeXlive distribution. (I just updated about an hour ago.) I don't have any trouble compiling your sample documents. (Well, I added "Hello World" to the first one so it wouldn't be blank when compiled.)

Joseph Wright, who frequents these forums, may be able to give you a better answer, but looking at your log files and comparing them to mine, it seems to me that the problem may have to do with using an older version of the xpackages/xbase bundle with newer versions of xfrac and siunitx. An update for xpackages came through on my system yesterday (I tend to update every day; a little obsessive I admit). It's possible that you updated right before that made it to your CTAN mirror.

In your first example, your error comes when processing xtemplate.sty, which is part of the xpackages or xbase bundle (which xfrac calls). Mine is dated 2010/09/20 v2037; yours is dated 2010/04/14 v1896.

Comparing our log files in the second case, we are both using the very recent siunitx 2010/09/26 v2.0v. However, you are loading xparse 2010/05/23 v1927 and I am loading xparse 2010/09/20 v2037. xparse is also part of the xpackages or xbase bundle.

If I were you, I'd try updating again and see if the new version of xpackages/xbase had made it through to your repository yet. (I don't know much about MiKTeX, but I assume you can refresh packages whenever.) Perhaps that would fix your problem.

Hi,

Thanks for your post!

I tried updating, several times, and from a couple of different repositories, actually. No luck. The timing of this little problem is rather ill... I'm trying to get a paper out Ahh, Murphy.

Any further ideas I might try?

Cheers!

[frabjous]

If you're really in a hurry, you could try one of the online LaTeX compilers (here's a list), and see if any of them do any better.

(Or send me a private message and I can try to compile your document, assuming you trust a strange with it, and you're sure it's ready to go.)

Oh, and if it helps, I use http://carroll.aset.psu.edu/pub/CTAN as my repository.

[cbkschroeder]

You're very kind; thank you. I'm at the "I'd like to get the first solid draft done by the end of the week" stage. Unfortunately, my supervisor is not a LaTeX user; he just likes to see nice pdf's. It would be nice to compile-and-see frequently, but I suppose I can live without for a day or so if I have to. Thanks for the nice links, too.

Barring success with your repository - I'll try that shortly - are there any ideas you might put forward as to how I could solve this? Why would MikTeX have such different versions? I would have thought running the update wizard would take care of everything like this. For the record, I can reproduce this problem with more than one of my machines - unfortunately.

Cheers.

I doubt the difference is between MikTeX and TeXlive. I'm fairly sure that when it combines to contributed packages, they use precisely the same parts of the various CTAN repository mirrors. It's just that some updates make it to certain CTAN mirrors faster than others. But as I said before, I'm not that familiar with MiKTeX. (It doesn't run on linux.) Do try the PSU mirror, but I'm not sure what to suggest if that doesn't work.

[josephwright]

You should be able to get the 'self-install' files expl3.tds.zip and xpackages.tds.zip from CTAN and do a local installation. TeX Live got fixed almost immediately, so the problem is MiKTeX (as there is only one person to do the updates).

I checked that with most recent packages on a MiKTeX 2.8 system after update from today (repository version 3924, dated 2010-09-29). I had no problems with the following examples (file lists added).

Hello all,

Thanks for your interest and feedback on this.

I ran updates this morning using the MikTeX update wizard and sure enough updates, which fixed my problem, propagated through. Certainly a learning experience for me; I've never had this happen before.

Anyway, thanks again!

Christian
