metadata.cc doesn't build (exif 0.25 & 0.27)

[David Hunt]

I’ve struggled to get metadata.cc to compile and get a bunch of errors

‌

metadata.cc:72:15: error: ‘AutoPtr’ in ‘class Exiv2::Image’ does not name a type
   72 | Exiv2::Image::AutoPtr open_exiv2(const Glib::ustring &fname)
      |               ^~~~~~~
metadata.cc:279:15: error: ‘AutoPtr’ in ‘class Exiv2::Image’ does not name a type
  279 | Exiv2::Image::AutoPtr exiftool_import(const Glib::ustring &fname, const std::exception &exc)
      |               ^~~~~~~
...

I’m not sure how others are getting it to compile. I’ve changed the code from using AutoPtr to using std unique_ptr’s (which I believe is what exif 0.28 is going to be using) and now it builds fine for me (on exif 0.27).

Let me know what you think of this change.

hi,

thanks for reporting. I build with 0.27.2 and never got any problem. however, I'll make sure art is ready for 0.28

metadata: use std::unique_ptr instead of Exiv2::Image::AutoPtr

Fixes #55
