compile errors for include sys/socket.h

[Franca]

Hi all!!
I'm new to this mailing list and I really hope that someone could help me...

I'm trying to compile a C program (implementation of a native method to be 
called by a java program) with gcc-4.1.2 and I obtain the following errors:

gcc -c -Wall  -I/usr/include/dbus-1.0 -I/usr/lib/dbus-1.0/include 
-I/usr/lib/jvm/java-1.5.0-sun/include/ 
-I/usr/lib/jvm/java-1.5.0-sun/include/linux -o 
rtnl.o rtnl.c

make: *** [rtnl.o] Error 1

I'm working on a debian testing, kernel 2.6.18, glibc 2.3.6-2 and libc6.
Do you know if these errors depend on my system configuration?   

I really don't know how to solve these conflicts... 
Any help is greatly appreciated :)
thanks in advance
