I (with the help of some others after I had already something to show) once "convinced" the Linux version of the Intel C/C++ compiler to generate FreeBSD native binaries. I did this because I thought it could be possible and had interest to give it a try. No business behind, no market to satisfy. I don't know the specifics of this nvcc, but with a little bit of interest and motivation, maybe something similar could be done. > Some guy from Universit=E4t Saarbr=FCcken proposed in his final thesis > soem stuff, but it hasn't been picked up by BSD people. Linux folks I don't understand what you talk about here, but links to his final thesis may be much more interesting for some people than to not even know the title of this final thesis.
