Hi, I was motivated to install Sage from the Graph Theory example on

http://mvngu.wordpress.com/2009/06/24/sage-4-0-2-released/ (the

release tour). To run it I downloaded tkz-berge.sty and tkz-graph.sty,

but I still get the error Unknown environment "tikzpicture" on running

the example.

Doing some testing it was pointed out to me that \usepackage{tikz}

needs to be in the header of the tex file in order to avoid getting

this error when rendering the tex file manually. That appears to be

missing.

Where could I add that to get this example and other LateX Graph

Theory output to work?

Some details in case it is important, I'm running 4.02 on Ubuntu 9.04

and I had to follow the advice here:

http://groups.google.co.uk/group/sage-devel/browse_thread/thread/53ae33d0324d44/888575a45f3f43c6?lnk=gst&q=illegal+instruction#888575a45f3f43c6

because the binary packages used optimizations my processor doesn't

have and compiling from scratch failed.

Thanks

Hi there,

you possibly just need to install the newest pgf tex package. You can

download it from

http://sourceforge.net/projects/pgf/

unpack the tgz file, copy the contents of the pgfXXXX inside a

location where your tex system can find it,

if you want a local installation just for one user, this is normally

~/.texmf-config/tex

but I don't use Ubuntu, so your location might be different. If you

want to be sure, just execute

kpsepath tex | tr : '\n'

and look at the output. Then go to the directory ~/texmf.config and

execute the command

mktexlsr .

(don't forget the dot at the end of the line!) to inform your tex

system that you have new packages there. You should be able to use the

tikz package now.

Cheers

Javier

Oh, I forgot to mention, Ubuntu 9.04's pgf is at the latest version

2.0

I think my first message was really unclear. What I meant was, if I

include \usepackage{tikz} at the top of a tex file and render it

manually on the command line, then I don't get the Unknown environment

"tikzpicture" error, but if the file doesn't have \usepackage{tikz} in

the header it gives an error equivalent to Unknown environment

"tikzpicture".

Thanks though

That is exactly what you should expect, since the tikzpicture

environment is only defined when you are using the tikz package.

Perhaps we should update the documentation on the Sage graphs stuff to

make it (more?) clear that the output only makes sense in a document

that uses TikZ.

Right, I think I understand what you're saying. The problem is that I

got the

error when trying to run the example in Sage.

Now for some reason I didn't get the Unknown environment "tikzpicture"

in Sage, instead I got an error about not having tkz-arith.sty and

after

installing that and figuring out texhash, I got it working.

The only change I can think of is that I installed dvipng in the

meantime.

Maybe having dvipng is not better as

http://www.sagemath.org/doc/reference/sage/graphs/graph_latex.html

mentions, but actually required.

Taxman,

Thanks for the report. Current behavior is to support latex versions

of graphs by adding two "\usepackage" commands to the preamble. It is

possible tkz-arith.sty should also be added, and maybe something

bigger like tikz and pgf.

Also, the documentation could perhaps be improved by specifying just

what a tex environment needs to have so a standalone document will

compile when a sage latex-version graph is incorporated.

I don't think dvipng being present, or not, is relevant here, since

that merely affects if a PNG or PDF image gets created - it comes

after latex does its complaining.

Sample code below may help with understanding/debugging this

situation. This is now

http://trac.sagemath.org/sage_trac/ticket/6516

Rob

~~~~~~~~~~

sage: latex.extra_preamble()

''

sage: g=graphs.PetersenGraph()

sage: latex.extra_preamble()

'\\usepackage{tkz-graph}\\usepackage{tkz-berge}'

sage: latex

(g)

\begin{tikzpicture}

<snip lots of latex graph code>

\end{tikzpicture}

along with the two other packages, but only two \\usepackage commands.

My tex installation automatically had pgf and tikz, but those would

probably also be good things to include for clarity along with moving

the documentation about how to check if they are installed such as

check_tkz_graph() and have_tkz_graph() from

http://www.sagemath.org/doc/reference/sage/graphs/graph_latex.html to

perhaps the top explanatory part or another howto. Also I had no idea

where to put tkz-berge, tkz-gerge, etc. I just guessed, and it

happened to work after I figured out I needed texhash.

Also the standalone document suggestion is good too, perhaps all the

way up to a full minimal header or a full minimal document for those

that want to include a Sage generated graph into their documents with

the greatest of ease.

And if dvipng wasn't the change I certainly can't think of anything

else that caused the Unknown environment "tikzpicture" error to go

away.

Hi Taxman,

Thanks for the excellent suggestions - this is next in my queue. Yes,

some TeX guidance would be helpful, and I'm going to add some, but its

not going to become a full-blown tutorial on installing new TeX

packages. That's "out of scope." ;-)

texhash, mktexls-r, kpsewhich and some notion of which directory to

stuff the tkz-*.sty files will be there. A minimal template for a

standalone document is a great idea as well.

%latex_debug works great in a notebook cell, and I'll have to dig up

the analogue for the command line. I've found that very helpful when

working through these sorts of things.

Sorry you had a rough time of it, but your experience and guidance

will be useful. Thanks again for the suggestions.
