[postgis-devel] New GEOS + New PostGIS + Old GDAL =?utf-8?Q?=3D=3D_?=Trouble

[Paul Ramsey]

Every now and then, raster regression fails for me (crashes, tests failing), for what appear to be random, un-reproduceable reasons (other people's builds at the same revision work fine). 

I think I now know why: the common feature in all cases was updating my GEOS at some point (often-times at enough temporal distance from rebuilding my postgis that I didn't recognize it). This time I noticed though.

Both PostGIS and GDAL link GEOS. If I updated my GEOS, and rebuilt PostGIS, raster would fail on me, until I also rebuilt GDAL. Basically it means that any minor update in GEOS requires a rebuild of both PostGIS and GDAL.

I am hoping I've sidestepped this problem for the future by compiling GDAL --without-geos, we'll see if that works.

Hope this helps others,

P.
