DISCLAIMER: I know less than nothing about c or c++

I am getting the error listed below when building (git source), and from googling I suspect that the links listed has the answer but it is beyond my skill set to fix it seams, could some one please assist me?

This likely corresponds to a reported bug,

http://openvibe.inria.fr/tracker/view.php?id=165

We are working on it.


Best,
Jussi

Thanx it looks that way, I will keep an eye on the tracker issue.

Let me know if there is anything I can help with, even if it is just testing.

Hi Harag,

the problem should now be fixed in git master, you could try to compile that and let us know if it worked for you.


Thanks,
Jussi

So all works well untill I add a temporal filter, the designer crashes out if I run a scenario with a temporal filter in it.

This is the error i see in the terminal:

/openvibe/dist/bin/openvibe-designer: symbol lookup error: /home/phil/Development/openvibe/dist/lib/x86_64-linux-gnu/libopenvibe-plugins-contrib-signal-processing.so: undefined symbol: _ZN4itpp5zerosEi

Should I create a new issue for this?
Would compiling with --debug give more info?
