Hello everyone!I'm Porting a rtai/linux application to xenomai/linux.  Now 
I come across a problem:when I compile the kernel module of my program,I find a 
WARNING,
                    WARNING:“__fixunsdfdi”[freqmod.ko] undefined!
after compiling,I  insmod the module xeno_native.ko,then insmod my kernel 
module freqmod.ko,then I come across an error:
            insmod:error inserting 'freqmod.ko':-1 Unknown symbol in module
    dmesg,it tells me: 
                     unknown symbol __fixunsdfdi。
 
   Before being portted to xenomai/linux 
(linux-2.6.24,xenomai-2.4.3,gcc-4.1.1),it run ok in rtai/linux 
(linux-2.6.24,rtai-3.7,gcc-4.1.1),and I only transport the RTAI API to Xeno's 
native API. So what's wrong?  I'm looking forward to your answers! 
     Thank you very much !
