Undefined subroutine

[johnrellis]

I get "Undefined subroutine" with this command line:

Code Select Expand

$ exiftool -makernotes= exiftool-bug.2023.12.20.dng
Undefined subroutine &Image::ExifTool::QuickTime::WriteQuickTime called at /usr/local/bin/lib/Image/ExifTool/Writer.pl line 694.

$ exiftool -ver
12.70

Tested on Mac OS 14.1.

Also, when I use

Code Select Expand

-makernotes:all= it does what I intended. So I guess the issue is the obscure error message when I gave

Code Select Expand

-makernotes=.

Using this delete makernotes command, I get an error message, as shown below.  I was using the Oliver Betz install, which I uninstalled and reinstalled, but that didn't help.  So I uninstalled the Oliver Betz install and downloaded ExifTool from https://exiftool.org/exiftool-12.70.zip, but am still getting the same error message.  I am stumped, so I tried a reboot, but that didn't help either.
I'm using ExifTool aplenty, and everything else works great.  How can I fix the delete makernotes - undefined subroutine problem?

-MakerNotes=

-o

There's nothing you can do, it'll have to be fixed by Phil.

According to this post on the same subject, you could use -MakerNotes:all= in the meantime.

I forgot to add the error message.  Here it is:

could you post the sample image that shows this problem?

I went ahead and merged these two threads as it was the same topic.

I was also able to duplicate it by copying a MakerNotes from one of my original files into my test file and had the same error.

Code Select Expand

C:\>exiftool -P -overwrite_original -TagsFromFile 2012-07-28_15.42.05.Nef -MakerNotes y:\!temp\Test4.jpg

Ouch.  It is very unusual that I wouldn't be able to reproduce an issue like this:

Code Select Expand

> Image-ExifTool-12.70/exiftool ~/Desktop/exiftool-bug.2023.12.20.dng -makernotes= -o tmp
    1 image files created
(on MacOS 10.14.6)

Does this still happen if you add -config "" at the start of the command?

- Phil

Edit:  Ah, OK.  If I add that to my command then I see the error!!

[Phil Harvey]

I found the problem.  This bug was introduced in 12.69 with a change in the writing of makernotes as a block to CR3 images.

I'll fix this in version 12.71 which I hope to release later today.

12.71 is now available.
