Description

In the OSGeo4W64 installation on Windows 7, I am trying to use gdal_translate to create a LERC-compressed MRF raster, but it appears that LERC compression is not enabled. I am using GDAL 2.4.0-5. I was able to do this in previous versions of the OSGeo4W distribution.

This is what happens when I try to create a new LERC-compressed MRF file:
gdal_translate -co "COMPRESS=LERC" -of MRF input.tif output.mrf
Warning 6: 'LERC' is an unexpected value for COMPRESS creation option of type string-select.
ERROR 4: GDAL MRF: Error setting compression
ERROR 10: Can't create output.mrf

And this is what happens when I try to read an existing LERC-compressed MRF:
gdalinfo test.mrf
ERROR 1: GDAL MRF: Compression LERC is unknown
gdalinfo failed - unable to open 'test.mrf'
