9 I would suggest trying crossdev with the target:
10
11 m68k-softfloat-uclinux-uclibc
12
13 See http://www.gentoo.org/proj/en/base/embedded/handbook/?part=1&chap=3
14
15 If it's supported directly in the linux kernel, then you might be able
16 to just use
17
18 m68k-softfloat-linux-uclibc
19
20 but I'm not sure if that will work.
21
22 Use uclibc for sure (no mmu). uClibc also has a dynamic / shared object
23 loader as well, which was developed in recent years, so even on mmu-less
24 systems you can still use functions analogous to dlopen(), dlsym() (AFAIK).
25
26 Of course, whether or not the patchsets are incorporated is another
27 story, but since Coldfire is a pretty well ironed-out architecture, I'm
28 sure you won't have any issues.
29
30 Using portage as a build tool for mmu-less systems is a great idea in my
31 opinion. I would suggest using Ned's crossdev-wrappers as well (search
32 the list).
