Hi all,
I just realized that the tool works as expected on GNUstep when being
logged in on the console of the machine supposed to run the service.
However, in production this service is supposed to be started by cron
with noone being logged in!? Any idea how to get around the
Abort (core dumped)Tools/OSMMapServer: Uncaught exception
WindowServerCommunication, reason: Unable to connect to X Server `'
problem then?
I forgot to mention that one needs to generate a window around the view
to get this to work. My tool code basically looks as follows now:
NSWindow *window = [[NSWindow alloc]
initWithContentRect:NSMakeRect(0,0, _imageSize.width,
_imageSize.height) styleMask:0 backing:NSBackingStoreNonretained
defer:NO];
MapView *mapView = [[MapView alloc] initWithFrame:NSMakeRect(0,0,
_imageSize.width, _imageSize.height)];
[window setContentView:mapView];
...
// fetch data from the database and do some magic with
NSBezierPath in drawRect:
...
[mapView display];
[mapView lockFocus];
NSBitmapImageRep *rep = [[NSBitmapImageRep alloc]
initWithFocusedViewRect:[mapView bounds]];
NSData *data = [[[rep TIFFRepresentation] retain] autorelease];
[mapView unlockFocus];
[rep release];
[mapView release];
[window release];
return data;
As reported in my last email this code works great on GNUstep as long
as I am looged in and have started the tool via Terminal.app. However,
starting the tool from a ssh session or via cron gives me
Abort (core dumped)Tools/OSMMapServer: Uncaught exception
WindowServerCommunication, reason: Unable to connect to X Server `'
! :-(
Hints still greatly appreciated!
Thanks,
Andreas
