question about building from source on windows

I'm going to summarize, just to make sure I have everything straight.

1) HEAD doesn't build (you get lots of "undefined reference to `_imp__FT_Done_FreeType'")
2) revision 3645 (yesterday before my setup.py changes), builds, but you got the float('inf') error (which is now fixed)
3) much earlier revisions (3608) have other issues (which seem to be related to out-of-date wxPython code)

I have just committed a possible fix for 1). You may want to try updating to HEAD and building that.

If that doesn't work for you, I'm worried about things getting out of hand and annoying a lot of people with my (well intentioned) setup.py changes yesterday. If that's the case, I will revert my build changes until I have a chance to sit in front of a Windows box and figure out what's really going wrong.

Apologies all around,
Mike

3608 also runs into problems of linking with the freetype libraries. Some much older versions (say in the 3500s) compile, but still crash python2.5.1 with errors like:

    It's not clear to me why you should be hitting mathtext at all, since
    the wxcursor_demo.py does not use it, as far as I can tell. Michael,
    would any of your earlier work caused him to get into mathtext
    inapproriately? You may need to revert a little farther, William, eg

I run from the command line. Essentially, it just goes poof. There is no output–it generates an error report (as usual in windows)–but nothing pops out that I can understand…

Cheers,
William

I see, it wasn't clear to me on my first look that the bug was
triggered at module load time.  I had assumed the bug was triggered by
*using* mathtext.  Since you seem to have found the fix (numpy.inf)
I'm happy to leave it as is.

Let me try this.

Ok–I reverted to head and it fixed the undefined references error and everything seems to build normally. But, if I try to run the embedding_in_wx4.py example, it crashes python 2.5.1

If I install from the .msi then things do work in python 2.5.1, so it must be something with the build.

I also tried to just start python from the command window, then ran:
import numpy as N
x=N.array([1,2,3])
from pylab import *
plot(x,x)
show()

The plot command generates a Line2D instance,

but the show() command kills python in the same way that the embedding example does. In the embedding example, I notice that the CanvasFrame is generated before the crash.

Cheers,
William

I also looked at the log_bar.py example and found that it’s also at the pylab.show() command that it dies

Just to clarify, you mean the 0.90.1 installer downloaded from SourceForge?

Does it also crash if you use the Agg backend alone and save to an image file?

import matplotlib
matplotlib.use("Agg")
from pylab import *

It's probably something in C++ backend code for Agg. Maybe someone else on this list knows the last time it built and worked on Windows and can track down a change that may have broken it.

It will probably take some work with a debugger to figure out where it is crashing. I'd be completely guessing at this point. If you feel adventurous and can get a C backtrace out of the crash somehow, (does gdb work with mingw?), that could be useful. Barring that, maybe one of the other Windows folk on this list has some ideas.

Thanks for your considerable patience :wink:

Mike

No, thank you for trying so hard.

I just tried running setup.py with VERBOSE=True on a clean installation.
when it crashes I get:
LazyValue::init_type

does this mean anything to anyone?

Just to clarify, you mean the 0.90.1

Does it also crash if you use the Agg backend alone and save to an
image
file?

import matplotlib
matplotlib.use("Agg")
from pylab import *
plot([1,2,3])

That's in the _transforms module. You might try with
matplotlib.use("Template") and see if it still crashes--not that I would know how to track down the problem in either case.
