- Three unrelated (or somewhat related) questions:
-
- 1. In other groups I've read that GCC 2.2 is the version to use
- and that 2.1 is buggy and shouldn't be used any more. Someone
- here mentioned an ST port of 2.2 but I haven't been able to find
- such an item at any of the ftp sites. Has 2.2 been ported to the
- ST, and if so, where could I find a copy?
-
- 2. Having just put an ICD AdSpeed STE in my system and added a
- floating point coprocessor, I was looking for a compiler that
- would support using a 68881 as a peripheral, like the ST's do.
- Does such a critter exist? I tried Laser C which supposedly
- has a library that supports this option, but noticed no time
- differences when running with software emulation or the hardware
- coprocessor (30000 adds, also 10000 sines seemed to take the
- same amount of time either way). I was hoping to see some of
- the claimed 10x speedup in some raytracing software I was going
- to port.
-
- 3. I have some .TGA files on my PC that I want to convert to
- PI3 (I think? the monochrome one anyway) to use as backgrounds
- on my STe. The utilities I've tried (Chameleon on the ST--I
- also looked at picswitch(?)--and piclab on the PC) don't have
- compatible file lists. Any suggestions on what utilities would
- be the best to do this conversion, and pointers as to where to
- get them?
