ScreenTest

1

Im using Octave 4.0.3 version on Windows 

Whenever i type "ScreenTest", i just get this error message.

-------------------------------

In place of the expected Octave .mex binary plugin file this placeholder file was executed:


  Screen.m


This MEX file seems to be missing or inaccessible on your Octave path or it is dysfunctional:


  Screen.mex


The following directory should be the *first one* on your Octave path:

 C:\toolbox\Psychtoolbox\PsychBasic\Octave3WindowsFiles\




If, on Octave-3.2.0, you have just installed Psychtoolbox, it worked properly and suddenly stopped working

after you have restarted Octave, then you may encounter a bug present in Octave 3.2.0.

Try the following at the Octave prompt: First type "savepath" + Enter to save the current Octave path again.


Then exit Octave and restart it. After that try again - It may work then, if the problem was caused by afore

mentioned bug.

-----------------------------

How can i fix it?

Looks like you're using an old psychtoolbox. Please install a fresh copy of the latest version.

Cheers,

I had exactly this problem when I upgraded to Octave 4.0.3 on Windows yesterday. In the detailed set of help messages from PTB, it offered several reasons why this might be happening. The main suggestion, which fixed it for me, was first to install Gstreamer, which I had not used with previous PTB installations. It also suggested that I needed to install a particular flavour of PTB (3.0.12 from memory), as this was required for the setup I had. So that might be important for you too depending on your system.
