If a straightforward plotting sequence, such as one of the examples,
does this, then it sounds like a broken installation, not a matplotlib
bug.
Based on your comment above, here are my particulars:
1) System is LinuxFromScratch recently built from their SVN book:
glibc is 2.5, gcc is 4.1.2, X is Xorg 7.2 installed in /usr.
2) Python 2.5.1 with Tkinter enabled. If I run the following script,
I get the 'quit' button which when clicked makes the button/window
disappear, so I know python and Tkinter are working.
#!/usr/bin/python
from Tkinter import *
class Application(Frame):
def __init__(self, master=None):
Frame.__init__(self, master)
self.grid()
self.createWidgets()
def createWidgets(self):
self.quitButton = Button ( self, text="Quit",command=self.quit )
self.quitButton.grid()
app = Application()
app.master.title("Sample application")
app.mainloop()
3) Numpy 1.0.3.1 installed without any errors and I can do the following:
>>> import numpy
>>> List = dir(numpy)
>>> len(List)
491
>>>
4) Matplotlib 0.90.1 also installed without error. I set
BUILD_TKAGG = 1 which may not have been necessary, but it seems to
have worked since in my matplotlibrc file I find "backend :
TkAgg". Then if I do this
" python simple_plot.py --verbose-debug", I get the output in the
simple_output attachment. The font errors there are the same as what I
get in each of my 3 XP installations where matplotlib works just fine,
so I don't think they are the cause of the segfault. As I may have
described previously, the plot window appears for a fraction of a second
and then disappears as the segfault occurs.
I also ran "strace python simple_plot.py --verbose-debug" with the
output that's in the strace_output attachment to see if that would give
any more information but that output ends at the segfault and I am not
knowledgeable enough to understand what it says.
Any help will be appreciated.
Best Regards,
Wayne
