Hi, everybody:

I'm now trying to write polygonized result into an esri shapefile, and I
tried

to add some field to the attribute table in the shapefile. But it corrupted

when i was trying to create an *ogrfielddefn* instance.The code goes

like this:
           OGRFieldDefn oField("归一化植被指数",OFTInteger);
           if(poLayer->CreateField(&oField) != OGRERR_NONE)
           {
                printf("create 归一化植被指数 failed!");
                exit(1);
           }
