Linux support is partly done but there is a lot more still to do
you can read this lengthy issue on github
and try the linux branch
to compile you can install the following packages …
sudo apt install build-essential libjack-dev libjack-jackd2-dev libgtk-3-dev php libx11-xcb-dev
then go to e.g. Examples\IPlugEffect and
make -f ../Makefile IDEBUG=YES APP
