GuestX>To my knowledge Castle have complied with the GPL by releasing the source to the HAL, I certainly have not seen any further complaints on that front. To be sure it would have been better,IMHO, if they had either *not* used that code at all or failing that if they had published the HAL source at the outset. Mistakes like this sadly do happen.
Regarding using RISC OS apps on Linux (or Windows - seen that the most effective RISC OS emulator runs on Windows) surely the point is that RISC OS would simply become a "layer" fully dependant on another OS. How happy would you be running Linux under emulation on top of Windows Vista?
While I have nothing against Linux (I even have an old Red Hat setup on an old PC at home) my purpose is *not* to promote Linux but RISC OS (I figure Linux doesn't need the help - it has enough already). I still consider the optimal option for RISC OS to be running on native hardware - anything else puts it at risk as it puts its future in the hands of others whose primary interests don't necessarily coincide with those of RISC OS users.
