[ECOS] linking problem

I am building the application for h8300 series  on linux.

I have built the toolchain, followed the
http://ecos.sourceware.org/build-toolchain.html  with
target as h8300-elf. and it is in /gnutools/h8300-elf

my system is installed Linux-9.0, kernel- 2.4.20-8
gcc native compiler version is 3.2.2 (which has been used to build the
h8300-elf toolchain).

GNU tools used:
        binutils-2.13.1.tar.bz2
        gcc-core-3.2.1.tar.gz
        gcc-g++-3.2.1.tar.gz
        newlib-1.11.0.tar.gz
        insight-5.3.tar.bz2

eCos - 2.0

I could not able to build the a simple 'c' program.

The following command used to build.

#mpco is the target which I have created.
ecosconfig new h8max                            // even I tried to build
h8300h_sim target
ecosconfig remove CYGPKG_LIBM       //since the math library build is
given problem & also right it is not required for me
ecosconfig remove CYGPKG_KERNEL   //Right now it is not required for me
ecosconfig tree
make

    j=8;
    k=i+j;
}

############ end of test.c ########



To compile and link with my small 'c' program. I used the following
command
h8300-elf-gcc -g -mh -I./install/include -L./install/lib -Ttarget.ld
-nostdlib test.c

I got following errors

What could be the wrong?
