Just to prove to myself that I could in fact build an ARM7
target, I've been trying the GDB/Armulator target with the
Skyeye simulator. My success rate hasn't been very good. I
was unable to build a 2.4 kernel using any combination of 3.4.1
or 4.2.1 toolchains and 20070808 or 20061213 distributions.
All four combinations with a 2.6 kernel built but only three of
them ran properly. Only one of the four combinations using the
current uClinux-dist release worked. Detailed results are
shown below.
Is there any documentation on which combinations of
dist/kernel/toolchain are know to work or fail? Perhaps a wiki
page somewhere that users could fill in? Since the three seem
to be pretty tightly coupled, it would be useful to keep track
wouldn't it?

Using gcc 4.2.1 (20070808) toolchain:
20070130 20080808
-------- --------
2.4 build fail[2] build fail[3]
2.6 OK no /proc filesystem
Using gcc 3.4.1 (20061213) toolchain:
20070130 20080808
-------- --------
2.4 build fail[1] build fail[1]
2.6 OK OK
[1] Same build failures seen with both 20070130/2.4 and
20080808/2.4 using 3.4.1 toolchain:
