When I connect "File" to "Scatterplot" I get an output window displaying the messages below. Do you know what I am doing wrong or how to correct the problem ?

Thank you

Dear Dimitri,

are you using windows or linux version of Orange? If you are using linux version and you built orange yourself, then let me know because I would guess that you have to change the optimization parameters when building orange.

Hi Gregor,

I appologise for responding so late. I am compiling Orange in Linux (SLES11). I used these instructions: ... 1.0-ubuntu


mkdir orangesvn
cd orangesvn
svn co

cd trunk/source
cd ..


Thank you ,
