Ok. I'm not sure if Cabbage will find the VST2.4 sdk inside the VST3 folder, but we can try it. First rename the "VST3 SDK" folder to "VST3SDK" so that it the folder name contains no white spaces. You may have this folder in the wrong place in fact. If should be in your home directory, rather than home. For example, the path should look like this:
mine is located at
With the SDK folder in the right place, navigate to the Cabbage/Builds/Linux folder from the terminal. Then try running the following command(replacing the SDK path with a valid one):
./buildCabbage "/usr/local/include/csound" "/usr/local/lib" "/home/Gyu_Park/SDKs/VST3SDK"
If you're lucky that should do it. Otherwise post back the errors you get. It might be best to copy and paste them into a text file and attach that
