Hi,

I am exploring the tutorial about the new acquisition driver. Driver was automatically generated and placed where specified.

I have registered my driver in: ovasCAcquisitionServerGUI.cpp (header and vector)
Do I need to register the configuration "CConfigurationTestDriver"? This is what I missed last time.



Currently my code fails with m_rDriverContext being NULL.

Please advise.

Hi Anton !

The only thing you need to use a new driver is registering it in the ovasCAcquisitionServerGUI.cpp file (#include and push_back in the vector), the configuration is not registered.
.. and if your driver is flagged as unstable, set AcquisitionServer_ShowUnstable to true in the config file.

I tried to assert the existence of m_rDriverContext too in a new empty driver, but couldn't reproduce what you are experiencing.
You didn't modify anything else, did you ?

Hello Laurent,

I have another problem that might be the primary problem.

When I add the new driver files in the project file something goes wrong with the compilation.

Visual Studio can not find <gtk/gtk.h> all of a sudden in ovasCConfigurationBuilder.h

Do you use VS 2010?

Please try to add the files I have attached. Does it compile with them?

Without the new files everything compiles and runs as expected.

Hello Anton,

Your source code works fine on my computer.
And seems very simple to me... no big deal except the assert part.

I use Visual Studio 2010.

Did you try cleaning the cmake cache and re-build from scratch the acquisition server ? (delete local-tmp/openvibe-application/acquisition-server)

Hello,

I regenerated projects and reconfigured the acquisition server in VS.

I found the problem. It is:



and not:



m_pDriverContext is NULL at that time

Please, change it

Hello Anton,

indeed there was an error in the tutorial. Thank you for your input, it is corrected now.

Cheers
Jozef
