installing matplotlib on ubuntu

Hi all, Hi John,

I remembered that there was a recent post on installing matplotlib on
Ubuntu.

I tried apt-get update without an error message, but running apt-get
install python-matplotlib-jdh gives me the following output.

Reading package lists... Done
Building dependency tree... Done
Package python-matplotlib-jdh is not available, but is referred to by
another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package python-matplotlib-jdh has no installation candidate

Apparently something changed since your post and now John. Is the
package still available? What else would be a convenient way to install?

Well, I fear my question will turn out to be stupid, but I really have
no idea where to look for my mistake anymore.

TIA
Christian

I recently installed matplotlib on ubuntu Breezy and it went fairly
well. I was having some problems that I thought were from John's
package not working on Breezy but turned out to be something else. I
ended up installing from source. It is fairly straight forward to
download the tarball and do a sudo python setup.py install. I ran
into some problems with needing the wxPython.h header file for the
WXAgg backend. If you look for a thread I started with the subject
"WXAgg's accelerator requires `wx-config'." you should find that Ken
and Arnd got me through it. Let me know if you get stuck anywhere.

Hi Ryan,

Thanks, but I too run into problems:
Doing python setup.py build is fine until:
<snip>
src/_na_backend_gdk.c:12:25: error: pygtk/pygtk.h: No such file or

Apparently the autodetection fails. Then I disabled all backends (except
for Agg, WX, WXAgg, which I want to use) and next time I tried setup.py
build:

WXAgg's accelerator requires `wx-config'.

The `wx-config' executable could not be located in any directory of the
PATH
environment variable. If it is in some other location or has some other
name,
set the WX_CONFIG environment variable to the full path of the
executable.

Sounds familiar, doesn't it? :wink:

Now, I tried to read on and in the end I am - frankly - completely
confused. Since I can't compile (I tried some other tweaks) ... is
somebody able to compile installation instructions? It appears that the
part on matplotlib's web page isn't up to date (how to build, the issue
with the debian's package, possibly other problems yet not seen by me?).
I would be willing to test everything shown to me and summarize this.
(Alas, I don't know how to build packages myself yet and I fear I won't
have the time to do anything quickly.)

Cheers,
Christian

I know this can be frustrating, but hang in there.

Your initial error about pygtk.h not being found is a dependency
error. You need some other packages and I am not sure what they all
are. They are generally the development packages. For this one,
search in the Synaptics package manager for pygtk and find
python-gtk2-dev (and probably python-gnome2-dev). You may run into a
few more of these. Whenever you see a *.h: No such file error, you
have a dev package missing.

The only way around the wx-config error is to download the wxPython
source tarball and find wxPython.h. Then copy it to
/usr/include/wx/wxPython/wxPython.h. I will attach mine, but this
may be a bad idea. You can download from their webpage here:
http://www.wxpython.org/download.php#sources
(grab the first one in the list that doesn't say RPM - it is the tar.gz file).

So, copying wxPython.h from the tarball or the attached file should
solve the wx-config error (you may need the other *.h files in the
same folder of the tarball). Working through the dev packages should
solve the errors with the other backends. I have TkAgg, GTKAgg,
WXAgg, and PS working on mine (there are probably others, but those I
have tested).

Let me know if you need more info.

Do you have the package "python-gtk2-dev" installed? You will need
this for the pygtk headers. Wx is a pain at the moment, but if you
are happy with gtk you should have no problems on ubuntu.

You will also need the packages tk8.4 and tk8.4-dev for the Tk backend
(your version numbers might be slightly less if you are on Hoary).

You might get all the development packages you will ever need in one
step if you install gnome-devel - but it is a huge package with a lot
of dependencies that could take a while to install. But it might
keep you from hunting for individual packages needed by mpl backends.

Are you using John's CVS packages or the stable-version packages at anakonda.net? It sounds like this might just be a matter of tweaking `/etc/apt/sources.list' appropriately, assuming we can figure out what the problem is.

Thank you, Ken, Ryan, and Charlie, for your help.
I'm sorry for the late reply, but I wasn't online over the weekend and
have got no time before.

Anyway, I managed to install matplotlib with your help and got no
serious complaint during compilation (simply neglecting a few warnings).
Importing matplotlib and pylab works. I didn't do any testing so far,
but at least I got to this point and you deserved some feedback before
I'll get to the testing, since this may take until tomorrow.

Cheers
Christian
