question about libc.a libgcc.a

[Hai Xu]

Dear all,

I am focus on a device driver. I compile it to a model.o and try to insmod
it to kernel. But when do so, I will get:

unresolved symbol: __udividi3
unresolved symbol: __umoddi3

As someone tell me, I have to link the libgcc.a to my model.o. I did it but
I when I try to insmod the model.o, I will get segamentation fault.

The following are my link libraries.
#LIBS    =
$(MATLAB_ROOT)/rtw/c/lib/$(ARCH)/lrtwLib.a -L/usr/lib/gcc-lib/i386-redhat-li
nux/2.96 -lgcc -L/usr/lib -lm -lc $(EXT_LIB) $(S_FUNCTIONS_LIB)
$(INSTRUMENT_LIBS)

Please give me some ideas about it.

Thanks in advance
Hai Xu
