You can't... there are a bunch of non-open-source binaries in the Windows release, that I just copy around. Also, I don't recompile Tcl within the Pd source tree; I do that separately and copy the binaries and .h files into the Pd source tree before compiling Pd. Here's a listing of the files I use (which you can copy from any binary MSW Pd release...)
hm ... i never thought i'd have download a binary pd release ...
anyway ... asio is closed source ... but i was curious how to build asiolib from the sdk ... it seems that pd is the only software using asio as a dll ...
btw, most of the sdk files are included in ./portaudio/pa_asio ...
cheers ... tim
