Ciao Enrico,

scusa il ritardo ma ero in vacanza... :-)

Ho modificato il setup.py in:

{{{
# file: setup.py
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext

SRC = "/home/pietro/docdat/src/gis/grass/grass_trunk/"
COMPILED = "dist.x86_64-unknown-linux-gnu/"
INCLUDE = "include"

setup(
    cmdclass={'build_ext': build_ext},
    ext_modules=[Extension("raster", ["raster.pyx"],
                           include_dirs=[SRC + COMPILED + INCLUDE, ], )]
)
}}}

ora se compilo non ho più warinings:

$ python setup.py build_ext --inplace --forcerunning build_ext
cythoning raster.pyx to raster.c

/home/pietro/docdat/src/gis/grass/grass_trunk/lib/python/cygrass/raster.so


ma se provo ad utilizzare la funzione mtype2gtype [0]:

In [1]: import raster
In [2]: raster.mtype2gtype('CELL')
Exception NameError: "name 'crast' is not defined" in 'raster.mtype2gtype' 
ignored
Out[2]: 0

Mi dice che crast non è definito...

Idee su come fare a definirlo?

Grazie per l'aiuto e i feedback.

Pietro
