[Gdal-dev] gdal_merge.py question

[Gillian Walter]

Do you have another version of python installed on your system?  If you 
do, windows might be trying to use that version rather than OpenEV's.  I 
seem to recall having a problem like that before on windows, but I think 
I just ended up uninstalling the other version.  If the presence of 
another version of python is what is causing the problem, the only thing 
I can think of to try other than uninstalling the other version of 
python is to make sure that openev's python21.dll is copied into 
OpenEV/bin and OpenEV/pymod in case windows will look in the current 
directory before system directories for library files.  You could also 
try downloading a version of OpenEV that uses a version of python 
consistent with yours.  I think Frank's latest build (OpenEV_FW_162.zip) 
uses python 2.2.something.  You can find these builds at 
ftp://ftp.remotesensing.org/gdal/openev/.
