How to build userland ?

	Hello,

	I'm trying to play woth L4ka. My compiler is :

cauchy:[~/openvms/root/build] > g++ -v
Using built-in specs.
Target: x86_64-linux-gnu
Configured with: ../src/configure -v --with-pkgversion='Debian 4.4.4-8' 
--with-bugurl=file:///usr/share/doc/gcc-4.4/README.Bugs 
--enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr 
--enable-shared --enable-multiarch --enable-linker-build-id

--enable-threads=posix --with-gxx-include-dir=/usr/include/c++/4.4

--with-tune=generic --enable-checking=release --build=x86_64-linux-gnu 
--host=x86_64-linux-gnu --target=x86_64-linux-gnu
Thread model: posix
gcc version 4.4.5 20100728 (prerelease) (Debian 4.4.4-8)

	I can build L4 kernel without any trouble but not userland. Process 
hangs with following error :

previously defined here

	If I understand, BI_NS and BI_NS2 are defined with same value : BI64. 
Thus, elf_find_sections() function is defined _twice_. I have no idea to 
fix this trouble. If I comment the second declaration of this function, 
build process hangs later with :

	In user/util/kickstart/Makefile.in, I have change LDFLAGS_amd64 as 
original Makefile tries to link 32 bits objects with 64 bits libraries.

# JKB
#LDFLAGS_amd64=     -b elf32-i386 --oformat elf32-i386 \
#           -N -m elf_i386 -L.
LDFLAGS_amd64= -N -L.

	Any idea ?

	Regards,
