What i try to do is to create an empty shapefile and later to open this shapefile and insert features into it. When i try to add the feature, a crash happens. Also i noticed that a field, which i created on the empty shapefile is not recognised when the empty layer is opened. Below is my source code and the debugger backtrace after the crash. A .tgz of the created files (.shp,.dbf,etc.) befor adding a feature is on ftp://ftp.geo.unizh.ch/pub/mhugent/newlayertest.tgz {{{ //create an empty layer and add a field to it OGRwkbGeometryType geomtype=(OGRwkbGeometryType)((int)vectortype); QString mOutputFormat = ""ESRI Shapefile""; QString mOutputFileName = uri; #ifdef WIN32 QString outname=mOutputFileName.mid(mOutputFileName.findRev(""\\"")+1,mOutputFileName.length()); #else QString outname=mOutputFileName.mid(mOutputFileName.findRev(""/"")+1,mOutputFileName.length()); #endif OGRSFDriverRegistrar* driverregist = OGRSFDriverRegistrar::GetRegistrar(); if(driverregist==0) { return false; } OGRSFDriver* driver = driverregist->GetDriverByName(mOutputFormat); if(driver==0) { return false; } OGRDataSource* datasource = driver->CreateDataSource(mOutputFileName,NULL); if(datasource==0) { return false; } OGRSpatialReference reference; OGRLayer* layer = datasource->CreateLayer(outname.latin1 (),&reference,geomtype,NULL); if(layer==0) { return false; } OGRFieldDefn fielddef(""dummy"",OFTReal); fielddef.SetWidth(1); fielddef.SetPrecision(1); if(layer->CreateField(&fielddef,FALSE)!=OGRERR_NONE) { return false; } }}} The debugger output when inserting a new feature afterwards: {{{ Program received signal SIGSEGV, Segmentation fault.
