Hi, I've been trying to compile csound on and off for the past two years and was never really successful: the closest I ever got to a working csound was a binary which would segfault every other run. So I gave it another try yesterday and again ran across some difficulties. Everything goes well enough until the linking stage at which point the whole things gives up and starts spewing messages such as this one: main.o(.text+0x341): In function `csoundMain': undefined reference to `POLL_EVENTS' Now, it appears that POLL_EVENTS is somehow related to graph generation; the problem is that I don't have any GUI installed on my system and therefore don't want to have anything to do with FLTK, TCLTK or X11, and it seems to be responsible for my problems. My question is: has anyone ever successfully built csound without the graph generation pieces? Any hint would be greatly appreciated.
