Subject: [spe-users] troubles with SPE
Reply-To: [email protected]

Folks, 
I'm a brand new user of SPE (at least, a wannaba one). My work relies heavily 
on matplotlib. In particular, I draw a lot of pictures, using the wxGTK 
backend. However, I have problems running scripts in spe, or using spe 
interactively. Here are some basic specs, first:

[GCC 3.4.3 20041125 (Gentoo 3.4.3-r1, ssp-3.4.3-0, pie-8.7.7)] on an AMD64 
machine
SPE v0.8.1.c .
wxpython-2.6.1.0 +gtk +gtk2 +opengl +unicode
wxGTK-2.6.1  -debug -doc -gnome +gtk2 -joystick +odbc +opengl +sdl +unicode 
+wxgtk1
matplotlib 0.82

When opening SPE, I get that message in bash:
>>> (python:9817): Gdk-CRITICAL **: gdk_draw_drawable: assertion `src != NULL' 
failed

But the window loads fine.

Then, I create a new file, copy-paste the tutorial code and try to run (by 
pressing F9, or Shift+F9, or ctrl+shift+F9). I don't get any feedback in the 
shell window (and yes, I have selected the 'redirect output to shell'. I got 
the following message from bash, though:

>>> sh: -c: line 0: unexpected EOF while looking for matching `''
>>> sh: -c: line 1: syntax error: unexpected end of file

Executing the code in shell loads the script OK, but doesn't recognze the 
'displayConstants' and 'doSum' functions (eg, I get that:
>>> File "<input>", line 1, in ?
>>> NameError: name 'doSum' is not defined
).
The class is loaded properly, though, and I can access the hello() method.

At last, I had the following:
>>> from pylab import *
>>> x=arange(10)
>>> plot(x,x)

which works when executed in shell, but
>>> show()
crashes spe. (the wxgtk window is created, it seems, but then it crashes).

I guess it's not SPE-cific pb, but more of a wxGTK one. I have no idea how to 
fix them, nore even where to start. 

Thx a lot in advance for your help.
P.

hi,

i've DL'd & unpacked SPE-0.8.1.b-wx2.6.1.0.-bl2.35 src.

my prereqs (all built from src into /usr/local) are, on OSX 10.4.3:

	PYTHON 2.4.2 / Framework
	LIBXML2 2.6.22
	LIBXSLT 1.1.15
	LIBXML2-PYTHON 2.6.22
	WXWIDGETS v2.6.2
	WXPYTHON v2.6.1.0

after UNinstalling any prior _spe traces, install with:

	cd /usr/ports/SPE-0.8.1.b-wx2.6.1.0.-bl2.35
	python setup.py install

completes, apparently, without error.

creating aliases for {spe, winpdb, debug_spe}, as per docs, then:

	%spe

results, however, on launch in:

	You need to install at least wxPython v2.5.4.1 to run SPE.
	Get it from http://www.wxpython.org
	Traceback (most recent call last):
	  File
"/Library/Frameworks/Python.framework/Versions/Current/lib/python2.4/site-packages/_spe/SPE.py",
line 7, in ?
	    sys.exit()
	NameError: name 'sys' is not defined


looks likes it's not getting *my* installed versions ...

suggestions?

thanks,

richard
