[Gdal-dev] pct2rgb.py

[Dobmeyer, Todd]

Frank

I downloaded the OPENEV_FW zip file that you recommended. I unzipped it
into the same folder that has the gdal folder. So both OpenEV_FW and
gdal are in their own folders inside the same "parent" folder. I typed
in the command:

gdal_merge.py -o rgb.tif blue.tif green.tif red.tif -separate

With the proper filenames of course. When I press Enter in command
prompt, I receive the following errors. What do they mean?

Traceback (most recent call last):
  File "C:\Support Libraries\OpenEV_FW\pymod\gdal_merge.py", line 76, in
?
    import gdal
  File "C:\Support Libraries\OpenEV_FW\pymod\gdal.py", line 152, in ?
    import _gdal
ImportError: DLL load failed: The specified procedure could not be
found.

Thanks again for your help!

Todd

Todd,

If you don't need to build everything yourself, I would suggest just
using the OpenEV_FW release for this task.

   http://gdal.org/dl/openev/OpenEV_FW_182.zip

It includes everything built nicely together, including the Python
numeric
package which would be needed for gdal_merge.py to work (as noted by
another
user).  On Windows when building GDAL you need to explitely set the
PYDIR
in nmake.opt to get python support working.  I think there are some
additional
complications related to the numeric support.  This is within your
ability to
handle, but unless you need to build things yourself for some reason I
would
suggest you avoid it.

Best regards,
