 		 #164561 - I'm told GCC is about the best there is ...
Responding to: ???'s previous message
and it comes with LINUX. A Linux-based (yes, disk drives and all) ARM system on a low-cost dev-board, with a mere GB of SDRAM doesn't cost much, and can be adapted to nearly any target environment.

As I've stated before, I've procured more than one ARM dev-board for $200 or less. Only the one from ATMEL, which didn't work at all, and cost well over $1k, not to mention the totally inadequate 4MB SRAM board that made up, supposedly, for the nonfunctional 16 MB SDRAM hardware on the chip, which cost another ~$500, and about $1200 for "software" of which none worked "as advertised", was more costly.

It makes little sense to build an ARM target that's not compatible with the LINUX OS via an adapter, when such a handy development platform is available.

The "Cheap cross-compiler" can be useful if one wants to develop code while traveling, but using the actual core as the host is always more efficient. It's like developing PC code on a PC.

The $5k compiler is what kept most of my colleagues from using ARM until it was LINUX-supported, and still keeps some of the Windows-only guys from using 805x. There are alternatives, thank God!
