Package a newer version of GEOS (3.2)

[ricardogsilva]

I have developed a plugin for QGis that requires GEOS >= 3.2 and Shapely >= 1.2 and would like to make it available for users of the osgeo4w packages. Please package a newer version of the GEOS library. Current version is 3.2 and the version offered by osgeo4w is 3.0. Thank you

Second it. It is pretty easy to reproduce errors while geoprocessing (intersects, clips, etc.) under (for example) QGIS in Windows. Under Linux (Ubuntu, GEOS 3.2) the same vectors/operations are handled flawlessly.

Hi,

Is possible to update geos to a more recent version rather than 3.0.3 ? The actually stable version of geos (3.2.2) is more affordable in spatial analyst.

I also second this request. I see crashes on Vista with gdaldev (1.8.0dev) when using GEOS functions because GEOS 3.0.3 doesn't have GEOSFree(), so we fallback to standard free() which causes immediate crashes

I'll try to do it this week.

QGIS will presumably have to be rebuilt with the new GEOS version so I've added Jurgen to the cc: list for coordination.

Upon investigation qgis does not seem to depend on the geos c++ ABI.

I have uploaded a 3.2.2 build done with VC9 to the OSGeo4W test environment. Testing and feedback welcome.

There's a missing .h that triggers an error while including geos_c.h

C:\utilisateurs\even\osgeo4w/include\geos_c.h(145) : fatal error C1083: Impossib
le d'ouvrir le fichier include : 'geos/export.h' : No such file or directory

GDAL would also need a recompile so to use GEOSFree() instead of free(). This is a compile time check :

        /* Since GEOS 3.1.1, so we test 3.2.0 */
#if GEOS_CAPI_VERSION_MAJOR >= 2 || (GEOS_CAPI_VERSION_MAJOR == 1 && GEOS_CAPI_VERSION_MINOR >= 6)
        GEOSFree( pabyBuf );
#else
        free( pabyBuf );
#endif

I have uploaded a -1 version of the package with the extra include file, and rebuilt gdal-dev with the new GEOS.

Thanks. Works nicely.
