Hi,
I'm newbie in Linux land. I'm trying to build a small router for GPRS
applications and I downloaded last version of uclinux
(uClinux-dist-20070130) and m68k-tools (m68k-uclinux-tools-20061214)
for a M5272C3 EVB.
It compiles fine for default options, but when I set routing
functions, linker stage for libnfnetlink doesn't works.
Here it's output:

[root@localhost uClinux-dist]#
It didn't works for kernel 2.4 neither kernel 2.6
I also compile my own version of tools just to see if that solves the
problem, but it doesn't.
I guess all problem is a symbolink link to tell compiler where to
search for uClibc libraries. But problem is where to put symbolic
link?
I also have tried switching from uClibc to uC-lib and kernel and
libraries stages compile fine, but user apps won't compile.
By the way, uC-lib isn't to old now for user apps now?
I also change user to root, isn't the best practice, but I have to try! ;)
