Hi Navneet, As far as I am aware the only decent way to do this in C is to only reference a global variable using "extern" in your header file, and then define it in a different file that is only built once (often a .c file). See for instance, "saul_reg" in "sys/include/saul_reg.h" and "sys/saul_reg/saul_reg.c"
