Hi,
I noticed PostGIS wasn't available for F23 / PG95 in yum.postgresql.org
and looked into the issues. Apparently SFCGAL 1.2.0 didn't build on F23
due to a change in CGAL, upstream fixed this in release 1.2.2 so I just
downloaded the latest tag from github and updated the spec to match,
attached.
After fixing that I ran into issues building PostGIS on F23 wrt linking
to GDAL. That required adding a -fPIC flag to configure when linking
with GDAL as well as removing the LD_LIBRARY_PATH setting in .spec.
Attached patches for .spec and for PostGIS's configure.
Cheers,
Oskari
