Hi folks, I've managed to port (ok, compile...) my scheme for max external on windows. I've got it building on VS 2019, and am successfully making a mxe and mxe64. Max on Parallels is recognizing the object is there, in that I can put a s4m.scm object into an object box, and then Max crashes before anything else happens. On mac, I know how to see what went wrong in xcode, but I'm at a loss on windows where to go from here. Any suggestions most appreciated! iain
