[gdal-dev] ImportError when importing gdal module with python 2.7 on Windows 7 64-bit

[Joaquim Luis]

I am also (moderately) interested in this.
 From what I remember, Even once explained us that the problem is that 
official Python binaries are built with VS2008 (or 9) and the GDAL from 
Tamas is from VS2010 and so the dlls are incompatible. However, I did a 
home built of Python with VS2010 and still got problems of this kind 
(not sure of the details anymore).

> I usually struggle with the same problems over and over again. Try using Dependency Walker (http://www.dependencywalker.com/) to see if you are missing a library or two. I used it to determine that I was missing these two files:
>
>      msvcp100.dll
>      msvcr100.dll

> I remember something about Microsoft removing these during some updates. They might be needed in your path.
