[Matplotlib-users] Compile and/or import problem

[Cindy H. B. <cho...@pr...>]

I'm having some problems compiling matplotlib 0.7.1 on solaris 8.  I 
believe I have all the prerequisites there.  If I try to compile with 
setup.py as it is originally, immediately it complains with "sh: 
pkg-config: not found", and finally dies after working a while.  If I 
change "BUILD_GTKAGG = 0" it compiles with some complaints like

/usr/local/pkg/python/include/python2.3/pyconfig.h:856:1: warning: 
"_XOPEN_SOURCE" redefined
<command line>:1:1: warning: this is the location of the previous definition

But seems to work.

When I try to import it I get:

ghia{chodgins}120: python
Python 2.3 (#1, Sep 12 2003, 16:47:52)

line 16, in ?
    from _gtkagg import agg_to_gtk_drawable
ImportError: No module named _gtkagg
 >>>

I'm not sure how to proceed from here.  I also am not a python 
programmer, just a system administrator trying to get this installed.  
Any help or fingers pointing me in a direction are greatly appreciated.  
Thanks.

This will keep it form building the GTKAGG back end...do you need that?

You're getting this error because you don't have the GTKAGG back end, 
which makes sense, as you told setup.py not to build it.

The problem is that your matplotlibrc file sets gtkagg as the default 
back end. First, try this:

 >>> import matplotlib
 >>> matplotlib.use('Agg')
 >>> import pylab

If that works, then you seem to have a working matplotlib with the Agg 
back end. If you generating plots that you want to save as PNG and use 
ion a wed site or something, you're done. You should also be able to use 
it with wxPython. Tkinter may also work. If you do need the PyGTK back 
end, I can't help you, except to say that make sure you have PyGTK 
working first.

To change the default back end, edit matplotlibrc:

http://matplotlib.sf.net/.matplotlibrc

Good luck,

-Chris

I believe this is a solaris compiler bug -- we've seen it a couple of
times before.  Search the matplotlib-users mailing list archives for

_XOPEN_SOURCE

at http://sourceforge.net/mailarchive/forum.php?forum_id=33405

I can't remember the answer, but I know there are a few posts on the
subject there...
