Hi,
is it possible to build python shapely lib under cygwin?
The installation of the Shapely-1.0.7 tar file was successfull, but now
I get this:
$ python
Python 2.5.1 (r251:54863, May 18 2007, 16:56:43)
[GCC 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)] on cygwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from shapely.geometry import Point
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "shapely/geometry/__init__.py", line 1, in <module>
from geo import shape, asShape
File "shapely/geometry/geo.py", line 5, in <module>
from point import Point, asPoint
File "shapely/geometry/point.py", line 10, in <module>
from shapely.geos import lgeos, DimensionError
File "shapely/geos.py", line 48, in <module>
lgeos = PyDLL('libgeos_c.so')
File "/tmp/python.6884/usr/lib/python2.5/ctypes/__init__.py", line
340, in __init__
OSError: No such file or directory
Of course there is no libgeos_c.so on Windows. But libgeos_c.dll.a
exists in /usr/local/lib (I compiled geos-2.2.3).
Is there a possibility to point shapely to this dll?
Changing
lgeos = PyDLL('libgeos_c.so')
manually and replace it with
lgeos = PyDLL('libgeos_c.dll.a')
has no (positive) effect.
I also wonder about
"/tmp/python.6884/usr/lib/python2.5/ctypes/__init__.py".
Why /tmp..?
I am not so familar with cygwin now, but there is no possibility to use
a "real" unix environment at the moment.
Did I made something wrong when installing shapely or libgeos?
regards
Stefan
ps. i managed to install in shapely directly in Windows (using the
windows installer), but I also need ogr libs, which came with fwtools
and the new shapely lib does not work out-of-the-box with the old python
version (2.3.4) in fwtools.
