Im trying to play with MLdc, but before my call to mldcConnect even completes I get a message printed to the console: "MLdc: Warning: no devices found on this system" and then my app crashes.

What am I doing wrong? This is my entire program:

The message means that you don't have any MLdc modules (ie: devices) installed on your system. Without any modules, your app will not be able to control anything through the MLdc API. Our next Beta release will include a small sample module.

However, your app should not crash if there are no modules. This could be a bug in the API, I'll check it out. Can you describe your system configuration? (OS version, etc.)

Sorry, I hadn't paid enough attention to your listing.

mldcConnect() does not allocate space for the system handle -- you must supply a pointer to a properly allocated area in memory in which to store the handle.

ie, try the following:

This should work without crashing (but it won't solve the "no devices found" issue).

Thank's for the reply, I guess I'll wait for your next release to play with it. The other issue was a rather foolish error on my part, thanks for pointing it out.

So, without any modules / examples the OpenMLdc seems to be uselesse or what can I do now with the current release ?

The main idea and concept of OpenML/OpenMLdc is excellent, no question. Hope to see soon some examples.

Some detailed documentation of the interface would also be nice.

Are there any more popular hardware manufactorers (i.e. ATI,NVidia,Creative Labls etc.) to support OpenML in the near future?

In response to Tactive's post:

detailed documentation of the API is available in the OpenML specification document (downloadable from the Khronos website).
