Build failure on Debian 13

Sat Aug 16 10:36:55 BST 2025

Hi,

The Exiv2 0.25 API must not be a problem. I compile all bundles with
this Exiv2 version (Windows, MacOS, and Linux) without problem.

Check if you don't have more than one version of Exiv2 API installed
on your system. Library is less tolerant in this kind of context. Only
one version must be installed on your system.

After that, clean up all your previous build, reconfigure, and try again...

Best regards

Gilles Caulier
