Install problem (Cross compile AVR32)

[Jeremy Bowen]

Hi 

Could someone please help with a basic installation. I've spent several days 
on this and I suspect I've overlooked something obvious and it's probably 
staring me in the face but I can't see it.

Here's my setup. I'm attempting to build a complete Linux development 
environment for the AVR32 target in order to diagnose an issue with a 
pre-compiled binary environment.

My main working environment should be installed in "/usr/local/avr32"

I successfully built and installed binutils-2.17.atmel.1.2.6

I can build the basic gcc-4.2.2.atmel.1.0.8 (with "--enable-languages=c" so no 
support for C++ at this point)

I have done a "make install" for the c compiler and updated my $PATH to 
prefix "/usr/local/avr32/bin" to it.

Next I built the linux kernel and installed it on my target system. (It boots 
linux and seems to run OK)

Next I did "make headers_install INSTALL_HDR_PATH=/usr/local/avr32"

Now I'm trying to build and install uClibc (from svn) and I'm getting confused 
about the various paths that I should use. 

I have the following in my .config
# Library Installation Options
#
SHARED_LIB_LOADER_PREFIX="/lib"
RUNTIME_PREFIX="/"
DEVEL_PREFIX="/usr/local/avr32"


uClibc appears to build OK. I have attempted to install this using:
make install PREFIX=/usr/local/avr32/ RUNTIME_PREFIX= DEVEL_PREFIX=

I'm trying to compile a simple "Hello world" test program but it cannot find 
lib/libc.so.0 (See appended verbose output from the compiler)

I have libc.so.0 in /usr/local/avr32/lib as the following "ls" shows:
/usr/local/avr32 # ls -al lib/libc.so.0
lrwxrwxrwx 1 root root 27 2008-10-22 11:29 lib/libc.so.0 -> 
libuClibc-0.9.30-rc2-svn.so

In summary:
===========
I'm not sure if this is a problem with my gcc configuration or uClibc 
installation/config.

I would really appreciate someone letting me know the suggested values for the 
various *_PREFIX settings, whether I should set these in my uClibc .config or 
if I should set them as variables in the "make install"  step (or both)
A general sanity check on the rest of my configuration would be appreciated.

Thanks in advance.
Jeremy
