Mips Cross Compiler Problem

[colin.spier@ukonline.co.uk]

Dear All,

I'm trying to build a mips-elf cross compiler on a Red Hat 6.2 Host.  
I'm using binutils-2.10.1 and gcc-2.95.2, and have configured/built 
them as follows:


Binutils
--------
~/gnutools/binutils/binutils-2.10.1/configure --target=mips-elf --
prefix=/xusr/apps/tools --exec-prefix=/xusr/apps/tools/M-i686-pc-linux-
gnu --program-prefix=mips-elf- -v 2>&1 | tee configure.out

make -w all 2>&1 | tee make.out

make -w install 2>&1 | tee install.out


Gcc
---
~/gnutools/gcc/gcc-2.95.2/configure --target=mips-elf --
prefix=/xusr/apps/tools --exec-prefix=/xusr/apps/tools/M-i686-pc-linux-
gnu --program-prefix=mips-elf- --with-gnu-as --with-gnu-ld --with-
newlib --nfp -v 2>&1 | tee configure.out

make -w all-gcc LANGUAGES="c c++" 2>&1 | tee make.out

make -w install-gcc LANGUAGES="c c++" 2>&1 | tee install.out



Everything seems to configure, build and install OK....



Now for the problem!  I've got a simple "Hello World" program, which I 
build with:

mips-elf-gcc -mcpu=r4000 -mips2 -msoft-float -g -c -O0 -Wall -I. -
I../../../../../thirdparty/rtos/ecos/my_build/install/include -
ffunction-sections -fdata-sections -D__ECOS hello.c -o hello.o

mips-elf-gcc -mcpu=r4000 -mips2 -msoft-float -g -nostartfiles -
L../../../../../thirdparty/rtos/ecos/my_build/install/lib -Wl,--gc-
sections -o hello hello.o -nostdlib -Ttarget.ld

This fails at the link stage with the following errors:

Am I missing something?  Have I done something stupid?  Does anyone 
have any ideas for how I can get around this problem?

Thanks in advance!

Colin.
