matplotlib-users Mailing List for matplotlib

Hi John,

I let gentoo/portage decide where all the applications are built to and it 
overrides the default configure settings to put things into /usr rather 
than /usr/local - i think the rational is that if I am letting portage/gentoo 
handle the management of a package then it should be ok in /usr. That way 
anything that I build that there is not an ebuild for goes into /usr/local.

Anyway - I checked that the output of 'pkg-config --cflags-only-I pygtk-2.0'
it is - '-I/usr/include/pygtk-2.0 -I/usr/include/glib-2.0 
-I/usr/lib/glib-2.0/include' 

And pygtk-2.2.0 is/was installed into /usr and there were no problems so I 
don't think that that is the cause of the problem.

I actually don't even have a /usr/local/include directory - I have never 
manually installed a programme which keeps its headers available!

Cheers
Chris

One thing that puzzles me.  If you installed pygtk-2.3.97 from src,
normally it would go to /usr/local rather than /usr, unless you
specified a --prefix (did you?). 

The error message suggests that matplotlib is using /usr rather than
/usr/local for pygtk

Do you have a /usr/local/include/pygtk-2.0 directory?  If so, it may
be that your PKG_CONFIG_PATH may need to be updated to see the new
install.  See man pkg-config for help on this environment variable.
You want to make sure that matplotlib sees the right pygtk; matplotlib
uses 'pkg-config --cflags-only-I pygtk-2.0', so you can debug your
setup by making sure this command is returning the right path to pygtk-2.0.

JDH

pygtk was built from source (I use gentoo and the ebuild does nothing out of 
the ordinary).

I just re-emerged pygtk-2.3.97 and got the same result. I have attached the 
full output from python setup.py build in both cases - if you want to sent it 
to the pygtk people that would be great.

Chris

PS just for the pygtk people's info I have gentoo linux with: 
gcc version 3.4.2  (Gentoo Linux 3.4.2-r1, ssp-3.4.1-1, pie-8.7.6.5)
kernel is gentoo-dev-sources-2.6.8-r4
python-2.3.3
gtk+-2.4.9 (this actually gtk+-2.4.9-r1 onto gentoo therefore it has been 
patched in some way).

Did you or can you build pygtk-2.3.97 from src or did it come from a
package manager?  Could it be a gcc-3.4.2 problem with pygtk-2.3.97?
If so, the pygtk folks would probably like to hear about it.

If you have minute to test compile pygtk-2.3.97 and let me know, I
would be happy to forward the results on to the pygtk mailing list in
case of failure.

JDH

Thanks very much.

It worked - (mostly)
I made the change you suggested and resolved that error - unfortunately it 
still did not build with pygtk-2.3.97 so I replaced that with pygtk-2.2.0 and 
it worked. Below is the error I got with pygtk-2.3.97 - it appears to be the 
same as an error reported already on matplotlib-users under the title 
'[Matplotlib-users] matplotlib and pygtk 2.3.96'. It seems that in that case 
upgrading to pygtk-2.3.97 helped, but here it did not. But I have a working 
matplotlib and I don't really care what version of pygtk I have to that is 
fine for me.

From a very quick read of the cxx code in that region, it looks like a
cxx bug.  I don't know why it is only exposed in gcc 3.4.2.  Try
replacing the function in line 2270 of CXX/Objects.hxx with

       const_iterator (const MapBase<T>* m, List k, List::iterator p )
           : map(m), keys(k), pos(p)
           {}

map(s) has been replaced by map(m).

The cxx code was not written by me, but this looks like a clear bug.

Hi,

I cannot build matplotlib-0.63.4 on gentoo linux. The error I get when running 
python setup.py build is:

I have python 2.3.3, GCC 3.4.2, Numeric 23.3, numarray 1.0, pygtk-2.3.97 (I 
ungraded from pygtk-2.2.0 but that did not help), and wxpython-2.4.2.4

I hope that is enough information - do I have the wrong versions - or am I 
missing something - I had no trouble building matplotlib-0.62.x

Hi,

look at this:

>>> from RandomArray import *

>>> normal(2,2,10)
 array([ 2.,  2.,  2.,  2.,  2.,  2.,  2.,  2.,  2.,  2.])

This is Numeric 23.1 compiled on my AMD64!!! I ran the same tests on a 32bit 
P4 and it ran fine.
Has anyone else seen this before?

For those that didn't understand, the normal function as called above,  is 
supposed to give me ten samples form a normal distribution with mean = 2 and 
standard deviation = 2

luckily:

>>> from numarray.random_array import *

>>> normal(2,2,10)
array([-0.04525638,  4.31467819, -0.17468357,  5.29377031,  0.84202135,
        5.29593539,  4.69651532,  1.61354655,  1.10839236,  1.7743317 ])

If anybody still needed a reason for switching to numarray, there you go!

I anybody here subscribes the numeric or numarray mailing lists (i.e. if they 
even exist) could you please forward this message to them?

That's the normal behavior of TeX math-mode.  I believe you want:

   \rm{versus \ some}

--Matt

I just downloaded the latest matplotlib (0.63.4) for Windows XP. I got 
rid of my font cache to make sure they would be re-generated. I have two 
questions/issues:

1) The font cache was not re-created, for some reason.

2) The spacing in math text does not seem to be rendered. I may be doing 
something wrong. I have tried this in both the TkAgg and GTKAgg 
backends. If i modify the example script mathtext_demo.py so the line

title(r'$\Delta_i^j \hspace{0.4} \rm{versus} \hspace{0.4} 
\Delta_{i+1}^j$', fontsize=20)

becomes

title(r'$\Delta_i^j \hspace{0.4} \rm{versus some} \hspace{0.4} 
\Delta_{i+1}^j$', fontsize=20)

the space between 'versus' and 'some' is not rendered on my machine.

If you have any idea why that is, i'd be very grateful.
Thanks,
Dominique

I've recently installed the latest version of pygtk which is now 2.3.97
and matplotlib 0.63.0 and they did not give any install problems.

I would recommend
remove the directory 'python2.x/site-packages/matplotlib'
remove the directory 'build' of your matplotlib install tree
install pygtk 2.3.97
install matplotlib 0.63

Steve
