[Zoo-discuss] ZOO WPS - Potential GEOS bug

[Jonathan mayer]

Dear List,
I have been trying to get shapely to work within a zoo service but it always fails when accessing geos - it can't locate the library.
Shapely works at the commandline and in another Apache CGI Python test file that I have set up so I believe that I have set up my environment appropriately


I am using Docker to automate much of this process and the problem is replicable.
As an aside - I am hoping to produce comprehensive ZooWPS Dockerfiles for the community but I am a beginner in Linux/Docker & ZooWPS, so it is all a little hard!!
Please view the following relevant Docker files in order:-
Generic GIS setup - All prerequisites etc

Specific ZooWPS et al set up code:-

Many thanks for your assistance.

The test service is very simple:-
#!/usr/bin/python pythonimport libxml2import osimport sysimport zooimport shapely
import shapely.wkt

def testrecreation1(conf,inputs,outputs):    outputs["Result"]["value"]=\            "Hello "+inputs["a"]["value"]+" from the ZOO-Project Python world !   " + str(sys.path)    return zoo.SERVICE_SUCCEEDED


The error message is:-

Message: TRACE: (10, 'No child processes')<type 'exceptions.IOError'>Unable to run your python process properly. Please check the following messages : ['  File "/var/www/cgi-bin/testrecreation1.py", line 8, in <module>\n    import shapely.wkt\n', '  File "/usr/local/lib/python2.7/dist-packages/shapely/wkt.py", line 4, in <module>\n    from shapely import geos\n', '  File "/usr/local/lib/python2.7/dist-packages/shapely/geos.py", line 66, in <module>\n    _lgeos = load_dll(\'geos_c\', fallbacks=[\'libgeos_c.so.1\', \'libgeos_c.so\'])\n', '  File "/usr/local/lib/python2.7/dist-packages/shapely/geos.py", line 33, in load_dll\n    lib = find_library(libname)\n', '  File "/usr/lib/python2.7/ctypes/util.py", line 253, in find_library\n    return _findSoname_ldconfig(name) or _get_soname(_findLib_gcc(name))\n', '  File "/usr/lib/python2.7/ctypes/util.py", line 246, in _findSoname_ldconfig\n    f.close()\n']
