A PostgreSQL configuration variable postgis.backend allow end user to control which backend he want to use if SFCGAL is installed (GEOS by default).

And also allow to use SFCGAL rather than GEOS for some 2D functions provided by both backends (like ST_Intersection or ST_Area, for instance). SFCGAL can be used to provide additional 2D and 3D advanced analysis functions to PostGIS cf Section 7.21, “SFCGAL Functions”. SFCGAL, version 1.3.1 (or higher), 1.4.1 or higher is recommended and required to be able to use all functionality. GTK (requires GTK+2.0, 2.8+) to compile the shp2pgsql-gui shape file loader. The drivers you want to use as described in Section 3.2, “Configuring raster support”. GDAL (pseudo optional) only if you don't want raster If compiling with PostgreSQL+JIT, LLVM version >=6 is required GDAL, version 2+ is required 3+ is preferred. JSON-C is currently used to import GeoJSON via theįunction ST_GeomFromGeoJson. LibXML2 is currently used in some importsįunctions (ST_GeomFromGML and ST_GeomFromKML). GEOS geometry library, version 3.6 or greater, but GEOS 3.12+ is required to take full advantage of all the new functions and features. The Proj library is used to provide coordinate reprojection support within Other versions of make may not process the Some other ANSI C compilersĬan be used to compile PostGIS, but we find far fewer problems whenįor many systems, GNU make is the default version PostgreSQLįor a full PostgreSQL / PostGIS support matrix and PostGIS/GEOS support matrix refer to Of PostgreSQL (including server headers) is required. Refer to the PostgreSQL installation guides if you haven't already Versions of PostgreSQL are not supported. It can be builtĪgainst PostgreSQL versions 12 - 16. PostgreSQL server headers access in order to compile. The PostGIS module is an extension to the PostgreSQL backend server.

Use these to experiment with the in progress releases of PostGIS

We also have very bleeding-edge windows experimental builds that are built usually once or twice a week or whenever anything exciting happens. If you are a windows user, you can get stable builds via Stackbuilder or PostGIS Windows download site Pre-Built Packages for various OS are listed in PostGIS Pre-built Packages Or another OS, you may find additional more detailed help at PostGIS User contributed compile guides and PostGIS Dev Wiki. This section includes general compilation instructions, if you are compiling for Windows etc In many cases compilation is only necessary if you want the mostīleeding edge versions or you are a package maintainer. Many OS systems now include pre-built packages for PostgreSQL/PostGIS.
