This is a wild guess, but isn't the -lorocos-gnulinux and other -l'flags' 
supposed to be at the end of the CC command ?

From the gcc man page :
-l library
           Search the library named library when linking.  (The second 
alternative with the library as a separate argument is only for POSIX
           compliance and is not recommended.)

           It makes a difference where in the command you write this option; 
the linker searches and processes libraries and object files in
           the order they are specified.  Thus, foo.o -lz bar.o searches 
library z after file foo.o but before bar.o.  If bar.o refers to
           functions in z, those functions may not be loaded.

           The linker searches a standard list of directories for the library, 
which is actually a file named liblibrary.a.  The linker then
           uses this file as if it had been specified precisely by name.

           The directories searched include several standard system 
directories plus any that you specify with -L.

           Normally the files found this way are library files---archive files 
whose members are object files.  The linker handles an archive
           file by scanning through it for members which define symbols that 
have so far been referenced but not defined.  But if the file
           that is found is an ordinary object file, it is linked in the usual 
fashion.  The only difference between using an -l option and
           specifying a file name is that -l surrounds library with lib and .a 
and searches several directories.
