Problem with GNU Mach compilation

HHi all:

I'm trying to compile GNU Mach from GNU Hurd, using the sources from git
repository.

I based on this guide:
https://www.gnu.org/software/hurd/microkernel/mach/gnumach/building.html
But, during the latest step (make gnumach.gz), It returns a linker error (I
attach the log file)

My steps were these:

-

git clone git://git.savannah.gnu.org/hurd/gnumach.git
cd gnumach/

apt-get build-dep gnumach

autoreconf --install

mkdir build
cd build/

./configure --prefix=
make DESTDIR=~/gnu install-data

git clone git://git.savannah.gnu.org/hurd/mig.git
cd mig

autoreconf --install

mkdir build
cd build

GNU=~/gnu

TARGET_CPPFLAGS=-I"$GNU"/include ../configure --prefix="$GNU"

PATH=~/gnu/bin:$PATH
export PATH

cd ../.. #Return to gnumach/build

mig
make gnumach.gz


How can I solve this?
