I have posted a couple questions regarding the use of weave.inline. Because I have not received any feed back I thought I might provide some more clues to the problem that I am having. As a refresher, I have the following versions installed: numpy-1.0.4.win32-py2.4.exe scipy-0.6.0.win32-py2.4.exe python-2.4.4.msi wxPython2.8-win32-unicode-2.8.6.1-py24.exe pywin32-210.win32-py2.4.exe I have also installed SDK toolkit and other related modifications (This appears to work) I also installed MinGW and this appears to work. MS XP SP2 First problem: There appears to be a problem with numpy/distutils/exec_command.py. I had to comment out lines 67-70 (there about) in order to properly assign the python executable. Once I do this I get the next error. Second problem: Will not complete the weave.inline. Example of code here: a = 1 weave.inline('printf("%d\\n",a);',['a'], verbose=2, type_converters=converters.blitz) The c++ source file is created; however, the object file is not created. This would make me think there is a problem with the comiler but I have tried both SDK and MinGW and they both cause the same error. Does anyone have thoughts on why this might be happening. I get the same problem if I insall enthought as well. I will cross-post on numpy too.
