mips-elf problem


hello,all

The processes to build up mips-elf tools on cygwin

1. binutils-2.14

$ export host=i686-pc-cygwin
$ export prefix=/tools/mips
$ export target=mips-elf

$ /usr/src/binutils/binutils-2.14/configure \
  --host=$host --prefix=$prefix --target=$target \
  --with-gnu-as --with-gnu-ld -v 2>&1 | tee configure.log

$ make CFLAGS=-O2 LANGUAGES="c c++" 2>&1 | tee make.log
$ make install LANGUAGES="c c++"



2. gcc-3.3.1-3

/* set up the path for binutils executables */
$ export PATH=$prefix/bin:$PATH

$ /usr/src/gcc/gcc-3.3.1-3/configure \
  --enable-languages=c --enable-multilib=no --with-cpu=mips32 \
  --host=$host --prefix=$prefix --target=$target \
  --with-newlib --with-gnu-as --with-gnu-ld -v 2>&1 | tee configure.log

$ make 2>&1 | tee make.log
$ make install


3. newlib-1.12.0
$ /usr/src/newlib/newlib-1.12.0/configure \
  --host=$host --prefix=$prefix --target=$target \
  --with-newlib --with-gnu-as --with-gnu-ld -v 2>&1 | tee configure.log

$ make CC_FOR_TARGET=$prefix/$target/bin/gcc \
       AS_FOR_TARGET=$prefix/$target/bin/as \
       LD_FOR_TARGET=$prefix/$target/bin/ld \
       AR_FOR_TARGET=$prefix/$target/bin/ar \
       RANLIB_FOR_TARGET=$prefix/$target/bin/ranlib 2>&1 | tee make.log
$ make install

I then wrote a simple hello.c The compiler and assembler seem to work fine.
$ mips-elf-gcc -S hello.c         ---> hello.s
$ mips-elf-gcc -c hello.c          ---> hello.o
$ mips-elf-as hello.s -o hello.o

But, when I tried to compile/assemble/link, there is problem

$ mips-elf-gcc hello.c

I can reduce some errors by appending -lc -lnullmon to the compiling 
command and get
$ mips-elf-gcc hello.c -lc -lnullmon
