Thank you, still learning my way around things.
So after copying 90% of the my not working source code into the test
program and it worked there, it finally dawned on me to check the
Makefile. Duh! while I had removed all the shapelib calls from the
source code, I forgot to check the link line

did you read :
http://gdal.org/ogr/ogr__api_8h.html#7b67ea4ab5892c6720460dc7f66eca2d ?
You'll know the cause of the crash afterwards ;-)

Even,
Here is my test program:
$ cat testogr.c
#include "ogr_api.h"
int main() {
OGRDataSourceH hDSin;
OGRLayerH hLayerIn;
OGRFeatureDefnH hFDefnIn;
OGRwkbGeometryType layerGeomType;
OGRRegisterAll();
hDSin = OGROpen( "/u/data/routeloops-v2/25/25017/Streets.shp",

Riann,
hum, I think you've hit a classical problem with the use of the GDAL python
bindings. The root of your problem is likely the following line:
reader = RasterReaderWriter(gdal.Open(iFilename).GetRasterBand(1))
Currently the GDAL python bindings do a poor job with life cycle management of
Thanks Even,
I coded up a similar test program, and the works here so I'm looking
elsewhere.
Looks like ogdi on Debian installs libgdal.so so I just uninstalled
ogdi, since I don't think I use it. And I'm rebuilding gdal without that
just to make sure I have a clean system without any rouge

No, it's just that you are not yet accustomed to use it ;-)

Hi all,
Trying to convert a shapelib program over to OGR and have to say it is
very complicated.
I'm using: GDAL 1.7.2, released 2010/04/23
At the moment I stuck on:
hDSin = OGROpen( "Streets.shp", FALSE, NULL );
hLayerIn = OGR_DS_GetLayerByName( hDSin, "Streets" );
hFDefnIn = OGR_L_G
Thanks for the suggestion.
I have tried:
tileRaster = self.raster.ReadAsArray(xoff=offsetX, yoff=offsetY,
win_xsize=width, win_ysize=height)
and
tileRaster = self.raster.ReadAsArray(xoff=offsetX, yoff=offsetY,
buf_xsize=width, buf_ysize=height)
but the result is something like:
(array([],
I have recently started a new open-source project that will use gdal
extensively, named scikits.eartho.
The vision is to implement some advanced algorithms and ideas that we
develop and work with at the South African Satellite Applications Centre
(SAC) for use in Python (SciPy).
