Box algorithms are not accesible in the main window

Post by Lin »

Hi Yann.

I tried to build a simple scenario from your tutorial section:
http://openvibe.inria.fr/documentation/ ... rial1.html
When I drag and drop the "Sinus Oscillator" and the "Signal Display"-Box
in the applications main window, I can't mark, move or connect the boxes.
They are inaccesible.

I'm working with Windows XP, SP 2 and the OpenViBE 0.4.0 RC 4 Installer.
Everything seems to work fine, only the openViBE plugin inspector prints
several warnings: "[WARNING] Calling accessor on uninitialized algorithm".

Any hints to solve the problem would be great.

Hello Lin and welcome on this board,

the problem you are reporting sounds very strange (this is a first time :) ). Are you using 64 bits architecture ? Have you tried reinstalling OpenViBE ? Did you need to install Visual Studio 2008 redistributable package ? Are you sure you have XP SP2 (sorry for this question but sometimes, double check can solve things ;) ) Can you send me the log files that ou have in openvibe install dir/bin ?

The error reported by the plugin inspector are OK.

Are you using 64 bits architecture? ... Are you sure you have XP SP2...?
Yes, I have XP 32-bit SP2 (WinXP Professional Version5.1, Build 2600_xpsp_sp2_qfe.090206-1239: ServicePack2).
Have you tried reinstalling OpenViBE ?
I uninstalled OpenViBE and installed it again - but the behaviour remains.
Did you need to install Visual Studio 2008 redistributable package ?
No, but I had to install DirectX in order to run the 3D-engine.
Can you send me the log files that ou have in openvibe install dir/bin ?
I found the log files in the openvibe install dir/lib :-)...

Many Thanks, Lin

Lin,

I can't see anything abnormal in the log files you sent. Your problem is very strange and I'm afraid that the forum won't be the most appropriate way of communication to solve it. Would you join on the IRC channel #openvibe on irc.freenode.net so we can discuss & test this live ? You can PM or email me to choose a day & time to meet.

Best,
Yann

PS: for interested readers, I will post explanations as soon as we solve this :)

Hi Yann,

great, thank you for the help :) !
What about 14:00Uhr on Tuesday (1.9.) , Wednesday (2.9.) or Thursday (3.9.)?

In the meantime I tried to install openViBE on a different computer-system.
It has the same operating-sytem etc... (except the language is english,
but this shouldn't make a big difference?)
The same error occures on this system, but installing the Visual Studio 2008
redistributable package solves the problem :!: .

Unfortunately, installing the Visual Studio 2008 redistributable package has no
effect on my computer-system (I installed/uninstalled openViBE, the VS2008-
package in english/german etc...) .

Lin,

great that you achieved installing OpenViBE on other computers. I will include Visual Studio 2008 redistributable package in the next release for sure.

For the IRC stuff, I am connected on the channel daily so you can come and contact me there whenever you want.

Hello openViBE Users,

we changed the Colour Settings from 16 bit to 32 bit resolution in the Display Properties.
This corrects the curious behaviour. It seems very specific to my environment, but I hope
this helps anybody...

Many many thanks to Yann for solving the problem :mrgreen:!!

Someone reported a similar problem on Linux today.

Screen color depth should be 24 or 32 bits. I will check if that can be solved for lower color depths.
