Michael,
There have indeed been recent changes in const correctness of a few
methods returning or accepting a OGRSpatialReference* (cf
https://github.com/OSGeo/gdal/pull/7381), including
OGRGeometryFactory::createmFromWkt().
This requires a rebuild of code depending on the GDAL C++ API, as the
GDAL ABI generally changes between feature versions.

Hi,
I'm here to ask for help finding where this issue is. If I use an
earlier build it still works (these are R packages sf and terra that
are well tested against previous releases).
Has something changed with the headers structure for
OGRGeometryFactory perhaps? (I'm out of my depth for how to track this
down). If it's an issue on the R side I'll fix it there, but mostly
I'm here to ask what has changed on the GDAL side to result in this
symbol problem (or whatever it is I'm doing wrong).
using latest build 24afc75d3c3f2c85621e8b8d83f54a73b1d3ad33
I see

Using a prior build eca6f7bf17fe500ef4c0ba9793e93ea305bab1fc it works.
The offending code in terra is this (I think)
https://github.com/rspatial/terra/blob/ddcf84ce901a269ac13118d650efac16f89a8602/src/read_ogr.cpp#L694
In sf it is
https://github.com/r-spatial/sf/blob/main/src/gdal_read.cpp#L582
Thank you.
Cheers, Mike
