<br>
I'm not sure if this is exactly related to your issue, but here are my <br>
thoughts:<br>
<br>
I do know that the recent poppler release relies on the C++17 standard, <br>
and there was a recent change in GDAL to accommodate this (see <br>
<a href="https://github.com/OSGeo/gdal/issues/5071" rel="noreferrer" target="_blank">https://github.com/OSGeo/gdal/issues/5071</a> ).<br>
<br>
In my case (for the Windows / MS4W community) I had to patch GDAL 3.4.1 <br>
for this, but in your case you might want to grab GDAL-master from git <br>
as that will be easier to handle the new poppler.<br>
