I note you are using ubuntu 8.10, I have been compiling the kernel and
complete ramdisk image for the the cirrus development EDB9307a board
using ubuntu 8.04. When I rebuilt my laptop for Ubunutu 8.10 I have
had many problems - including the PATH_MAX problem you had.

This error is easy to get around - either #include <limits.h> or just
#define PATH_MAX with a number - I stuck in 4096 but you'd need to
check that value... not sure if the filesystem on the flash has a
limit hard coded.

The next bug I got on my system was that something was wrong with ar
when archiving a zlib library.
...
ar rc libz.a adler32.o compress.o crc32.o gzio.o uncompr.o deflate.o
trees.o zutil.o inflate.o infback.o inftrees.o inffast.o 
...
ar: error while loading shared libraries: 
libz.so.1: ELF file OS ABI invalid

At this stage I decided to switch back to ubuntu 8.04.

Perhaps you should as well?

I do realise the TS products may be different but thought my
infomation might be of use to you - I read this group sporadically as
I have TS7200 and TS7400 boards but am using the EDB99307a because of
its builtin LCD interface. (http://arm.cirrus.com)
