orocos

Hello are Angelo,  
I would like to install OROCOS but I have some problems. I am using the
distribution Linux fedora core 3 on base AMD Athlon(TM) XP1800+.  
I have installed RTAI 3.1 in /usr/realtime with kernel 2.6.8.1 with
patch hal7-2.6.8.1.patch; makes a will it and it works.  
I have installed the in demand softwares for OROCOS on my base. After
that write the followings commands:
  
tar - xvzf orocos-0.18.0.i386linux.tar.bz2  
cd orocos-0.18.0  
  export PATH=$PATH:$(pwd)/tools/bin  
  export ECOS_REPOSITORY=$(pwd)/packages  
  mkdir build  
  cd build  
  .. / configure-- with-lxrt=/usr/realtime  
make new_packages  
make configure_packages  
make all  
  
And until here everything well, then write  
  
make check  
  
and at the end I get this:  
  
g++ - I/usr/local/include - g - or parser-test test-runner.o
state_test.o dispatch_test.o function_test.o types_test.o program_test.o
- L/usr/local/lib - lcppunit - ldl.. / packages/install/lib/libtarget.a
- lboost_signals - lpthread - L/usr/realtime/lib - llxrt

I have tried to do the  
 
.. / configure--with-gnulinux   

and the make check goes to good end.  
Another effected test has been done using the Mandrake 10.0 but I always
has problems with the make check with a library of the boost.  
How can I resolve this problem?   
Is there a distribution linux and of RTAI that allows me to install
OROCOS without problems?   
Thanks
