Still wrapping my head around this, C can be a headache compared to Java


I have two files, test1.c, and test2.c

test1.c:

Quote

test2.c:

Now in the command line, I am trying to learn 2 things.
1. How to simply compile these 2 files together?
My incorrect approach was: gcc -o test test1.c test2.c

2. How to create a makefile with these 2 files together?
Don't know how to start.

I guess I am misunderstanding how global variables work in this scope. Should it just be part of a header file, or is there a way to incorporate it otherwise?

I goggled 'using makefiles' and there was a pretty decent tutorial first hit I believe....

Yeah thats what I was using

but I think I am misunderstanding dependencies or something, because despite using those commands I cant get it to recognize that I am referring to test2.c with my function call in test1.c

I was hoping for a simple explanation in the case I described above, but maybe I just need to learn this more thoroughly

I believe you need to do



where your .h file declares the function print_totoy

That would make sense, thanks

Actually I think the prototypes / variables need to be declared externally in both files, and then it works fine. Seems to work ok now
