C-makefile and external libraries

Question

Where should I put -lm to include math.h library in my project?

@clear
@echo  
@echo Compiling  
@cc -c rpn.c   
@cc -c  stos.c   
@cc rpn.o stos.o  
@rm -f *.o  
@echo Compilation success

Answer 1

Functions from math.h are defined in libm library. To add a library, one should specify -l<name> parameter for the linker, where <name> is name of the library without the lib prefix. So just add -lm parameter to the linking command:

`cc rpn.o stos.o -lm`
