<p>Hi Luís,</p>
<p>it depends on your GDAL was built. <br>
</p>
<p>You can check it with "gdalinfo --format gtiff | grep LIBTIFF"
and it will return either LIBTIFF=INTERNAL or LIBTIFF=LIBTIFF,
Version X.Y.Z<br>
</p>
<p>If it is with its internal libtiff copy, then it corresponds
roughly to the state of libtiff master at then time the GDAL
release was done. Looking at
<a class="moz-txt-link-freetext" href="https://github.com/OSGeo/gdal/blob/v3.6.4/frmts/gtiff/libtiff/tiffvers.h">https://github.com/OSGeo/gdal/blob/v3.6.4/frmts/gtiff/libtiff/tiffvers.h</a>,
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</p>
<p>Even<br>

<div

am currently facing the <span>error "PREDICTOR=2 is only
supported with 64 bit samples starting with libtiff > 4.3.0</span>"
with GDAL 3.6.4. 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. <br>
