linux-2.6.12 kernel build with uClibc

[Tom Kirkpatrick]

Hi,

I'm trying to cross compile a a linux kernel for an embedded system  
which has been built with buildroot.

My setup is as follows:

  * buildroot (latest svn)
  * GCC 4.2 (2006-03-04 snapshot)
  * uClibc (2006-06-01 snapshot)
  * Binutils 2.16.1

I'm running make with "ARCH=i386 CROSS_COMPILE=i686-linux-" and I  
have the build_i686/staging_dir/bin set as the first thing in my PATH  
and I'm getting the following error:

...
include/asm/mpspec_def.h:78: warning: 'packed' attribute ignored for  
field of type 'unsigned char[5u]'
   CC      net/ipv4/tcp.o
In file included from include/asm/mpspec.h:6,
                  from include/asm/smp.h:19,
                  from include/linux/smp.h:20,
                  from include/linux/sched.h:27,
                  from include/linux/module.h:11,
                  from net/ipv4/tcp.c:252:
include/asm/mpspec_def.h:78: warning: 'packed' attribute ignored for  
field of type 'unsigned char[5u]'
net/ipv4/tcp.c: In function 'tcp_disconnect':
include/asm/bitops.h:61: error: inconsistent operand constraints in  
an 'asm'
make[2]: *** [net/ipv4/tcp.o] Error 1
make[1]: *** [net/ipv4] Error 2
make: *** [net] Error 2

I also seem to get "include/asm/mpspec_def.h:78: warning: 'packed'  
attribute ignored for field of type 'unsigned char[5u]'" for every  
single step of the make process. I know this in itself is probably  
nothing to worry about, but perhaps it's related to the final error  
I'm seeing.

has anyone seen this before?
or can anyone make any suggestions as to what I can do to try and fix  
it?
