Hi there. I've recently tried to port some code I wrote on pc to falcon using gcc cross compiler and I'm stuck on gcc options. If I use -m68060 alone my code doesn't work while if I additionaly specify -m68881 it works fine! I guess it's failing miserably somewhere in the clipping code which in turn is very fpu intensive. My understanding of 060 vs 68881 difference is that with softpack they're both the same. So I don't get it at all.
To sum up, do I really need to use both -m68060 and -m68881 ? Looking at Mikro's Quake port it looks like -m68060 alone does the job.
Cheers,
Sqward.
