My first suggestion is to make sure that you actually have the latest version of 1-6. I was having a similar problem before the official release and updating made this go away.

I am using areaDetector with Flea2 Firewire cameras on WindowsXP.

I can create a camera driver (WinFDC_Config) and pipe the output through a chain of plugins:

camera_driver -> process-> overlay -> NDStdArray -> stats

and everything works. I next tried to create an IOC with two cameras and found

{camera_driver_1, camera_driver_2} -> process
works, where process can receive output from one camera or the other. However

{camera_driver_1, camera_driver_2} -> process -> overlay
crashes. In particular the IOC crashes on start up at the last of these lines:

  NDOverlayConfigure("OVER1", $(QSIZE), 0, "PROC1", 0, 8, -1, -1)
  dbLoadRecords("$(AREA_DETECTOR)/ADApp/Db/NDPluginBase.template",...
  dbLoadRecords("$(AREA_DETECTOR)/ADApp/Db/NDOverlay.template"
  dbLoadRecords("$(AREA_DETECTOR)/ADApp/Db/NDOverlayN.template", ...

I get an error message "myIOC.exe has encountered a problem and needs to close". If I omit the last line the IOC will start up. Note that these are the same db files that work in the single camera IOC.


I don't know how to proceed. Hoping someone can suggest a next step. Any wild guesses as to what might be a problem?
