<div dir="ltr">Hey list (and salut SFCGAL guys).<br><br>I would like to use SFCGAL but can't make it work.<br><br>On a Ubuntu 12.04 LTS, Postgres 9.3, postgis 2.1, CGAL 4.2 , SFCGAL 1.0.2.<div><div><br></div><div><ol><li>
I compil &install CGAL : fine<br></li><li>I configure and compil SFCGAL : fine<br></li><li>I install SFCGAL : fine (see log)<br></li></ol></div><div><br></div><div><ol><li>I clean postgis : fine<br></li><li>I configure postgis : strange (see log) **SFCGAL version is marked as 1.0.0 where it should be 1.0.2<br>
</li><li>I compil postgis : fine (see log)<br></li><li>I install Postgis : fine (see log)<br></li></ol></div><div><div><br></div><div>Then I create a new database : </div><div><ul><li>CREATE DATABASE test_sfcgal;<br></li>
</ul></div><div>And try to add postgis</div><div><ul><li>CREATE EXTENSION postgis VERSION '2.1.0';<br></li></ul></div><div><br></div><div>Then I get the error message : </div><div><ul><li>"ERROR: could not load library "/usr/lib/postgresql/9.3/lib/<a href="http://postgis-2.1.so">postgis-2.1.so</a>": libSFCGAL.so: cannot open shared object file: No such file or directory"<br>
</li></ul></div><div><br></div><div>Yet libsfcgal.so is in "/usr/local/lib".</div><div><br></div><div>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?</div>
<div><br></div><div>I tried to configure postgis with a given sfcgal path : 'usr/local'</div><div>SFCGAL version is not detected in Postgis configure step.</div><div>Then I get error while building postgis (raster section)</div>
