I don't recall if I get the exact same error but I do get something similar. The build seems to stop with an error but it also seems to be only that the output is not updating. If I leave the build for a while (maybe 10 min) it will resume. My guess is that the output is buffered so you don't see that the build is still working. Try giving it some time first.

Normally, Matplotlib tries to build for everything that it can detect. I do a test where I take the matplotlib from the web-site and build it without installing it. There is information at the start of the build about which libraries that it found. I use that to test my system to make sure that it will build the ones that I want.

I build Sage from source and in that case it is necessary to set an environment variable. For example in bash: export SAGE_MATPLOTLIB_GUI='yes'. This then will tell it to try to build a gui.

You have a binary package which does not require running make. I don't know if that package will work as it uses newer libraries but you should be able to just run sage and try it.

The processing may have to directed by a person as the series is likely to include multiple samples and/or bad scans. This might mean grouping spectra while discarding unusable files. I am trying to come up with a scheme that is easy to use for the people using the instrument. They may be experts in their field but don't necessarily have strong computer skills. Any interface needs to be simple. I know from experience that any extra steps is a barrier. I had not thought of an @interact. That might be quite useful. There may be a different approach. I am also thinking of making a small local gui and using the remote Sage server. This would be something like remote-sagetex. This would also get around having the user manually zip things. They can just select the files and they are handled as needed. However, it means making the gui and I rather like the notebook. I have to think about it.

So I will simply put it down as being a bad idea. Using a zip-file is still an option. I called it unfriendly as it means that the user will have to use another program to prepare the data first. It isn't a deal-breaker though. I was mostly just wondering how other people deal with this situation or perhaps it doesn't come up with most Sage users.

[sage-support] Using many local files with remote notebook
Hi all, I often have multiple files for analysis. For example, I might have a few hundred spectra in a single directory as a single series. I want to run a script that loads them one at a time, does something on each, and returns a result in a final file. This works fine in a local setting. The question is, how I might do this with a remote server? Ideally, I would like to be able to set up a notebook that a user can (easily) use and work on a directory of local files. The user would be on a Windows machine and Sage would be on a separate machine. I can upload one file at a time to the notebook but that gets rather boring for a hundred files. :-\ I thought about using a zip file but this is not very user friendly. Is there a better way, i.e. to tell the notebook to use the local directory?

[sage-support] using Matplotlib and sagetex
Hi,
I would like to add plots to a document using sagetex and my script
uses matplotlib to generate the plot. Is it possible to matplotlib
with sagetex? I understand that /sageplot{} wants a
with a .save method. However, I have not found how to generate such an
object.
For example if I use the simple example:
sage: from pylab import *
sage: t = arange(0.0, 2.0, 0.01)
sage: s = sin(2*pi*t)
sage: P = plot(t, s, linewidth=1.0)
sage: xl = xlabel('time (s)')
sage: yl = ylabel('voltage (mV)')
sage: t = title('About as simple as it gets, folks')
sage: grid(True)
sage: savefig('sage.png')
Where is the ?
cheers,
Adam

I doubt the EEEpc has any development packages installed by default. You could start by looking at the SAGE installation guide. http://www.sagemath.org/doc/inst/inst.html Check to see if you have the basic packages installed. I see a number of missing header files including things like stdio.h and stdlib.h which are common files. (perhaps in libstdc++6-dev?) Other ones look like python files. Do you have python-devel installed? cheers, Adam PS For future reference: it is not usually necessary nor desired to post the entire error output unless asked.

[sage-support] problems building matplotlib on Ubuntu 8.04
Hi all, I have been having problems with Matplotlib on Ubuntu 8.04 (AMD-64). Specifically, I am having trouble with the backends. If I build Matplotlib separately I get the following for information about backends. OPTIONAL BACKEND DEPENDENCIES libpng: 1.2.15beta5 Tkinter: no * Tkinter present, but header files are not found. * You may need to install development packages. wxPython: 2.6.3.2 Gtk+: gtk+: 2.12.9, glib: 2.16.3, pygtk: 2.12.1, pygobject: 2.14.1 Qt: no Qt4: no Cairo: 1.4.0 In fact, I do have Tcl/Tk headers but they are not found. This is a known issue: http://www.mail-archive.com/[EMAIL PROTECTED]/msg02799.html However, when I look into the install.log file of Sage I find: OPTIONAL BACKEND DEPENDENCIES libpng: 1.2.15beta5 Tkinter: no * Tkinter present, but header files are not found. * You may need to install development packages. wxPython: no * wxPython not found Gtk+: no * Building for Gtk+ requires pygtk; you must be able * to "import gtk" in your build/install environment Qt: no Qt4: no Cairo: no It can not find anything and so does not build any and so various tests fail. I also tried using sage -python to build Matplotlib with the same result (no backends found). I was hoping to use another backend until a fix for the tcl/tk problem is found. Any ideas would be welcome.

Of course it wasn't 8.10. I am running Ubuntu 8.04. My mistake. :-) A.

Hi, I tried a few settings in matplotlibrc and found that TkAgg worked.

[sage-support] matplotlib show command not showing plot
I have recently had a problem plotting with matplotlib in sage 3.0 and now also in sage 3.0.1. Even if I try the simplest plot from the matplotlib tutorial, I don't get a plot. sage: from pylab import * sage: plot([1,2,3,4]) [] sage: show() sage: I have tried this in both the notebook and from the command line. I have also tried using sage -python and ipython. In all cases no plot appears. In fact nothing seems to happen. There is no window or plot and unfortunately, no error message. I have installed sage 3.0.1 from source on two machines. One is running Ubuntu 8.10 on AMD 64 and the other is a 32 bit machine running Scientific Linux 5.0. I also tried the binary: sage-3.0.1- rhel32bit-intel-sse2-i686-Linux.tar.gz. I have tried removing .matplotlib and .ipython from my home directory but this had no effect.
