Hi all,
  
  I am trying to compile the ARToolkit source code, but when I execute it, I get the following error:
  
  Camera image size (x,y) = (320,240)
  demoARSetupCamera(): Error loading file Data/camera_para.dat for camera.
  main(): Unable to set up AR camera.
  
  And so, the application exits. However, if I go to the ARToolKit  directory and execute the simplevrmld.exe it works. Have you ever had a  problem like this?
  I am using the 2.71.2 version...
  
  Thanks for your help...
  
  Marina

Thanks for your reply...
  
  And yes... I have this file in the indicated path, and if I go to the  ARToolKit directory and execute the simplevrmld.exe it works. The  problem just happens when I open the solution, compile it and so run it  by a development enviroment, like Visual Studio, for example. And I  really would like to change its source code, so it is a problem...
  
  Another idea about what could be this problem?

as the error already says, artoolkit does not find the camera parameter
file - called 'data/camera_para.dat' in your case.
make sure there is a file data/camera_para.dat relative to your
execution path.

So this is not specificaly about ARToolKit, but rather basic
VisualStudio project settings.

You have to set the correct execution path so that VisualStudio knows in
which folder to execute your program. If you do not specify a folder
VisualStudio will use the folder where your solution file is stored in.

Assuming you are using VS.NET 2003 do:
-> Project Properties (of the main executable)
-> Debugging
-> Working Directory

Daniel
