[gdal-dev] Internal libtiff version

[Luí­s Moreira de Sousa]

Thank you Even, that is helpful. This GDAL build is the one available from the stable branch of the Ubuntu-GIS PPA. I will bring this to attention with that community.

Regards.

Looking at https://github.com/OSGeo/gdal/blob/v3.6.4/frmts/gtiff/libtiff/tiffvers.h, I see we were already past 4.4.0, so it is likely you have a GDAL build against an external libtiff that wasn't as current as the GDAL build

Libtiff 4.3.0 was released in 2022, about a year before that version of GDAL. Is there a way to know which version of Libtiff is included with which version of GDAL? I searched the web site but could not find it.
