Hey list (and salut SFCGAL guys). I would like to use SFCGAL but can't make it work.
On a Ubuntu 12.04 LTS, Postgres 9.3, postgis 2.1, CGAL 4.2 , SFCGAL 1.0.2. 1. I compil &install CGAL : fine 2. I configure and compil SFCGAL : fine 3. I install SFCGAL : fine (see log) 1. I clean postgis : fine 2. I configure postgis : strange (see log) **SFCGAL version is marked as 1.0.0 where it should be 1.0.2 3. I compil postgis : fine (see log) 4. I install Postgis : fine (see log) Then I create a new database : - CREATE DATABASE test_sfcgal; And try to add postgis - CREATE EXTENSION postgis VERSION '2.1.0'; Then I get the error message : - "ERROR: could not load library "/usr/lib/postgresql/9.3/lib/ postgis-2.1.so": libSFCGAL.so: cannot open shared object file: No such file or directory" Yet libsfcgal.so is in "/usr/local/lib". Is it related to the fact that I have two postgres server (9.2 and 9.3, on port 5432 and 5433), even if only the 9.3 is running when installing etc? I tried to configure postgis with a given sfcgal path : 'usr/local' SFCGAL version is not detected in Postgis configure step. Then I get error while building postgis (raster section) /bin/bash ../../libtool --mode=link gcc -g -O2 -fPIC -DPIC -Wall -Wmissing-prototypes -I../rt_core -I../../liblwgeom -I/usr/include/gdal -I/usr/local/include ../rt_core/librtcore.a raster2pgsql.o ../../liblwgeom/liblwgeom.la -L/usr/lib -lgdal -L/usr/local/lib -lgeos_c -lc -lm -o raster2pgsql libtool: link: gcc -g -O2 -fPIC -DPIC -Wall -Wmissing-prototypes -I../rt_core -I../../liblwgeom -I/usr/include/gdal -I/usr/local/include raster2pgsql.o -o .libs/raster2pgsql ../rt_core/librtcore.a ../../liblwgeom/.libs/liblwgeom.so -L/usr/lib -lgdal -L/usr/local/lib /usr/local/lib/libgeos_c.so -lc -lm ../../liblwgeom/.libs/liblwgeom.so: undefined reference to `sfcgal_linestring_add_point' .... I also tried to install SFCGAL in a custom directory , then use the --with-sfcgal=the_directory I got the same error while building than when indicating 'usr/local' Postgis_full_version() before installing sfcgal : POSTGIS="2.1.0 r11822" GEOS="3.4.2-CAPI-1.8.2 r3921" PROJ="Rel. 4.8.0, 6 March 2012" GDAL="GDAL 1.10.0, released 2013/04/24" LIBXML="2.8.0" TOPOLOGY RASTER Any help appreciated, as I tried everything I could think of !
