Linux Ubuntu missing libproj.so.0 about geoscript-groovy HOT 6 CLOSED

I would suggest using the Directory Workspace directly. Really strange, that it's trying to load spatialite native library.

def tramosXsnaspe = tramos.intersection(snaspe)

def resultsWorkspaceName = "./Toltén"
def resultsWorkspace = new geoscript.workspace.Directory(new File(resultsWorkspaceName))

def tramosXsnaspeFileName = "tramosXsnaspe"
resultsWorkspace.add(tramosXsnaspe, tramosXsnaspeFileName)

from geoscript-groovy.

Jared, thanks for the very rapid reply and apologies for my slow uptake
(alligators quite deep right now).

I made the change you suggest and one of the spatialite messages goes away
but not both. This second message appears to be caused by the statement

resultsWorkspace.add(tramosXsnaspe, tramosXsnaspeFileName)

Interesting that there is a file called "tramosXsnaspe.fix" created which
appears to be data. Looking at it, I don't see any obvious strings. The
first few bytes are:

0000000 001 \0 \0 \0 \0 \0 \0 \0 g \0 \0 \0 \0 \0 \0 \0
0000020 \0 \0 \0 \0 001 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0 \0
0000040 002 \0 \0 \0 001 \0 \0 \0 \0 \0 \0 \0 003 \0 \0 \0
0000060 002 \0 \0 \0 \0 \0 \0 \0 004 \0 \0 \0 003 \0 \0 \0
0000100 \0 \0 \0 \0 005 \0 \0 \0 004 \0 \0 \0 \0 \0 \0 \0
0000120 006 \0 \0 \0 005 \0 \0 \0 \0 \0 \0 \0 \a \0 \0 \0
0000140 006 \0 \0 \0 \0 \0 \0 \0 \b \0 \0 \0 \a \0 \0 \0
0000160 \0 \0 \0 \0 \t \0 \0 \0 \b \0 \0 \0 \0 \0 \0 \0
0000200 \n \0 \0 \0 \t \0 \0 \0 \0 \0 \0 \0 \v \0 \0 \0

I wonder if this is related somehow; I've never heard of a .fix file as
part of a shapefile collection.

C'est ma façon de parler.

My project is done for now so I have a bit of time to try to sort some of these things out.

First of all, the .fix file is a known kind of shapefile-related artefact, apparently a kind of index for searching by feature id.

Second, the error:

java.lang.UnsatisfiedLinkError: /tmp/spatialite-3.7.22.4-libspatialitejdbc.so: libproj.so.0: cannot open shared object file: No such file or directory

The only libproj.so on my system (recently upgraded to Ubuntu 16.04) are:

/usr/lib/x86_64-linux-gnu/libproj.so.9
/usr/lib/x86_64-linux-gnu/libproj.so.9.1.0

Do you have any thoughts on this matter, Jared?

from geoscript-groovy.

I think the GeoTools docs explain what is going on here:

http://docs.geotools.org/stable/userguide/library/jdbc/spatialite.html

I believe you need to use the specifically built native libraries.

from geoscript-groovy.

Jared, thank you very much for this pointer. It has made the error message
go away.

Specifically, what I did:

1. downloaded the zip file of proj and geos and unzipped it (which
   creates a creates a directory called 'lib');
2. moved that directory into /usr/local/lib and renamed it to geotools
3. ran the following:

$ export LD_LIBRARY_PATH=/usr/local/lib/geotools
$ geoscript-groovy -Djava.library.path=/usr/local/lib/geotools test5.groovy
loading ../Hidros_finales_corregidos/Toltén/tramos.shp...
Apr 28, 2016 3:46:39 PM org.geotools.image.ImageWorker
INFO: Warp/affine reduction enabled: true
loading ../../BBNN/SNASPE.shp...
calculating intersection...
adding tramosXsnaspe to workspace ./Test...
...done.
$

Message gone!

So now my only doubt is that those libraries are OLD - 2012 vintage.
libgeos in Ubuntu 16.04 is 3.5.0 whereas in the zip file from the site it's
3.1.1

Maybe it's time to look at building something from source...

Anyway! Thank you tons for this. I'm really looking forward to pushing
geoscript a bit!
