any questions you have, just post in the forum, and/or on the percussa github. Would be good if you try posting on the ssp-sdk github project so I can confirm I get an email when you do so.
as long as you stick to normal C/C++ code it should just compile with the g++ (GNU) compiler, especially if you use the VST QVCA example I posted. Of course you still have to set up your linux development machine and put JUCE on it but as long as you can get that done you should be on your way.
Anyone actually compiled some VST yet? I have a programmer friend who might help me take a shot at it.
I am not up to date on that, but if you want to give it a shot all the info you need is here in the forum.
