Hello,<br><br>I&#39;m trying to build Csound with Csound VST in Linux and using a checkout from CVS. First it asked for the VST sdk files which I copied into the Csound source directory, but then I can&#39;t get pass this errors:

I thought it was only needed for vst4cs (which I&#39;m not building). I&#39;m using the VST SDK v 
2.4 since that&#39;s the one that had the same directory structure that the CsoundVST source looks for, so I assumed 2.4 is the right version to use. <br><br>I&#39;m trying to build CsoundVST because I want to start learning to build GUI&#39;s with Python and calling Csound from it. Do I have to build CsoundVST in order to have the Csound Python API? I tried importing the csound library using an installation of Csound without CsoundVST and I got this:
