compiling with uclibc?

[Jim Hauxwell]

Hi All,

I am hitting a problem building a gcc cross compiler toolchain for mips 
with uclibc.

The target is a uclibc linux platform running a 2.6.18 kernel.  I pulled 
the source for this and extracted it.  When I initially tested the gcc 
compilation it was missing pthread.h.  As I am on a mingw platform and 
don't natively have pthreads.

After a little digging in the uClibc tree I modified my command line to 
point to the uClibc include directory which got me further still.

I am now hitting an error

> make[2]: Leaving directory `/c/cygwin/usr/src/mingw/gcc-mips/libdecnumber'
> make[2]: Entering directory `/c/cygwin/usr/src/mingw/gcc-mips/gcc'
> The directory that should contain system headers does not exist:
>   /c/cygwin/usr/src/mingw/uClibc-0.9.30.1/usr/include

the usr/include doesn't exist, and I haven't go a set of kernel headers 
from the platform.  This seems to be a little chicken/egg as how can you 
build a kernel without a compiler and how can you make a compiler 
without a kernel??

A linux tree does have a usr/include directory in it, but it only has 
about 4 files in it and therefor I don't think this is the correct thing 
to be looking at.

Here is my config, I hope someone can shed some light on what I've done 
wrong.

# ../gcc-4.2.0/configure   --target=mipsel-linux-uclibc 
--with-build-sysroot=/c/cygwin/usr/src/mingw/uClibc-0.9.30.1 
--disable-__cxa_atexit --enable-target-optspace --with-gnu-ld 
--with-float=hard --enable-threads --with-arch=mips32 
--disable-libmudflap --disable-nls --with-gnu-plts 
--with-headers=/c/cygwin/usr/src/mingw/uClibc-0.9.30.1/include 
--enable-languages=c
