Introduction to my problem

I am trying to use scipy.weave.inline. I appear to get the same error no matter what compiler I try.

Please note that I am attaching a python script with examples of weave.inline that I have been attempting to implement. This is messy and there are a lot of commented lines but will be a start to demonstrate what I am testing. Hopefully this will help someone.

I have also tried to separate out the information below so it will read as easily as possible for any onlookers. Look at all section titles before digging too deep because they may not be in any intuitive order for those that are actual programmers.

Thanks for any insight. It was suggested from the scipy list that I post these here.

Also note, that there was an error in numpy for me. I had to comment several lines out before I got the weave error. This is included below as well.

Also, all of this is new so I appologize for not providing all the necessary information. And when I say new, I know python only a little and I have never compiled source files. I have a lot of scripting and VB background however.

Thank you,

Michael

Installed software and OS:

scipy-0.6.0.win32-py2.4.exe

wxPython2.8-win32-unicode-2.8.6.1-py24.exe

pywin32-210.win32-py2.4.exe

python-2.4.4.msi

numpy-1.0.4.win32-py2.4.exe

OS: Microsoft Windows XP Professional SP2

Platform: win32 nt

Python Version:

2.4.4 (#71, Oct 18 2006, 08:34:43) [MSC v.1310 32 bit (Intel)]

Processor:

Intel(R) Pentium(R) M processor 2.13GHz

x86 Family 6 Model 13 Stepping 8

I have also tried the most recent enthought binaries and I had the same problem.

Compilers:

MinGw

Cygwin

SDK 2003 toolkit

SDK 2005

(I followed the directions which I could find online with regard to setting up environment paths and modifications to the msvccompiler.py.

Error message:

From what I can tell the error seems to occur when compiling. the s,o =exec_command(cmd) does not write out to the two output files containing the s, o information. Looking at the files, I do not get the object file. Depending on the compiler this may be the .obj or .o file. The .cpp or c++ source file is created. I do not know if the compiler creates the cpp file or a library acts as an interpreter that writes the python to c++ which can then be converted to the object file. Or maybe it is something completely different.

Here is the error using mingw:

Code used for weave inline:

Please not that when I try any of these variations, I get the same error but I am trying to provide as much information as possible.

Example one

a = 1

weave.inline('printf("%d\n",a);',['a'], verbose=2,type_converters=converters.blitz)

For additional examples see attachment.

Error in Numpy:

Make the following changes to:

C:\Python24\Lib\site-packages\numpy\distutils\exec_command.py in order to get weave to work.
