Description
Here is the tip to avoid the following error message (on my Pi B+) according smbus
root@pi04:~/SDK# make
make -C lib all
make[1]: Entering directory '/root/SDK/lib'
make -C c libiteadc.so
make[2]: Entering directory '/root/SDK/lib/c'
gcc -O2 -fpic -shared -o libiteadc.so *.c -I../../include

edit the file lib/c/itead_wire.c and comment the line which include linux/i2c.h since I2C definitions are already in i2c-dev.h. It avoid duplication definition at compilation
include <linux/types.h>
//#include <linux/i2c.h>
