[rui zhu]

In recently project ,I need to use mysql in linux netfilter . So I linked the libmysqlclient.a with my .o file as a new file
new.o , but when I use command "insmod new.o", the error occurs as next :
The module you are trying to load (new.o) is compiled with a gcc
version 2 compiler, while the kernel you are running is compiled with
a gcc version 3 compiler. This is known to not work.
The commond I used to link is
ld -m elf_i386 -r -o new.o myfile.o -L/usr/lib -lmysqlclient -lz
All in C language
Can anyone helpme ,thank you very much.
