Hi  philmoz.
 I find a bit bug in dng.c  [116]:    {0x8825, T_LONG,       1,  0},      //GPS_IFD offset          
  change it :      #if defined(CAM_HAS_GPS)
                          {0x8825, T_LONG,       1,  0},          //GPS_IFD offset
                      #endif
  then work OK,ExifTool NO 'Warning ' .

Hi  philmoz.

  change it :      #if defined(CAM_HAS_GPS)

                      #endif
  then work OK,ExifTool NO 'Warning ' .


In the trunk version DNG code is in a module so it needs to be platform/camera independent. This means we cant use conditionally compiled code in the module.

The current DNG files passes the Adobe dng_validate program so this looks like a problem in ExifTool.
I will see if there is another way to exclude the GPS header record when I have some free time.

Are you compiling your own version of using the version on the autobuild server?
The existing code works correctly on all my cameras - so I'm wondering if it's something in the way you (or the autobuild server) are compiling it.

It would also help if you upload a sample DNG file (without your change) to a file share and post the link here.

    Revision 1808 (chdk) no sx210is. I porting sx210is from branches_revision 1806(CHDK release-1.0) ,in revision 1806(CHDK release-1.0) work OK.
  sample DNG file Later upload.

This a sample DNG file: IMG_3635.dng

Dng.c no be changed.


I can't see anything wrong with the CameraName or UniqueCameraModel data in that DNG file.
What program is telling you that something is wrong with UniqueCameraModel?

(dng_validate shows the correct value for both fields and shows no warnings or errors for the GPS data.)

Here changed dng.c [116] sample DNG:  IMG_3636_116_change.dng

Here changed dng.c [285][286]:

As I said earlier this is not appropriate code for the trunk version of dng.c
It also appears you missed this warning a few lines earlier in the file:
Code: [Select]
// Index of DNGVersion in IFD0 below.
// *** warning - if entries are added or removed this should be updated ***
#define DNG_VERSION_INDEX   22

Revision 1809 in the main SVN trunk should sort out the GPS inclusion/exclusion concern.
