Do you have the termios.h file on Mac OS X? If not, then we can use the HAVE_TERMIOS_H boolean that's set a few lines further down the CMakeLists.txt file and build IS900 conditionally based on that.

[rpavlik]

Ah, I bet that would work. I think I've dealt with this elsewhere and that's a Linux header or something

[casallas]

It seems like OS X does have termios.h, I'd have to check why it's not including it

[rpavlik]

Any luck on tracking this down? If not, I'd say just disable it on Mac (possibly using a check header configure time compile test), since the hardware is accessible through VRPN anyway.

[casallas]

I haven't looked further into this (maybe because I don't need/have the IS 900). I'm all for disabling it on Mac, at least for the time being.
