<p class="MsoNormal"><span style="" lang="EN-US">Hi dear
list, <br>
<br>
I am designing an application that uses GDAL (which seems to bind to Numeric) to
read an image and convert it to an array. The code runs without problem in the
console, then I compile it (apparently without problems), but when I try to
launch the application, it fails and the next error appears in the .log:<o:p></o:p></span></p>

<p class="MsoNormal"><span style="" lang="EN-US">I’ve not
found a version of GDAL that binds to Numpy. I am using GDAL from hobutools (v.
