how to write a makefile for c program multiple files

Run git push to save your work back to your personal repository. If you have any “conflicts” from Lab 0 (although this is unlikely), resolve them before continuing further. This will merge our Lab 1 stencil code with your previous work. If this reports an error, run: $ git remote add handout Start with the cs300-s21-labs-YOURNAME repository you used for Lab 0.įirst, ensure that your repository has a handout remote. If you are looking for a detailed tutorial on C, check out the links on our C primer. The main features of the C language include low-level access to memory, a simple set of keywords, and clean style, these features make C suitable and widely-used for system programming. Don’t be afraid to look up questions on Stack Overflow and Linux Man Pages (which provide great documentation on C library functions), and if that doesn’t help, ask on Piazza! Why C?Ĭheck out this article for more on why C programming is awesome! Here are some of the article’s highlights: C is an imperative programming language that was mainly developed as a systems programming language to write operating systems. If you take away anything from this course, hopefully, it’s that Computer Systems are not magic and that much of it actually makes a lot of sense. After this lab, you will also be more familiar with pointers and why C and C++ use them.

The purpose of this lab is to give you some experience with writing and understanding the syntax of C programs and apply the tools used to compile and run them. Completed the Diversity Survey – Your grades for Lab 0 and Lab 1 will depend on whether you’ve submitted this (though all questions are optional). Completed Lab 0 – This will ensure that your VM and grading server account are set up properly.Ģ. o file with rules such as the following: list.o: list.c list.Before attempting this lab, please make sure that you have:ġ. To remedy this, we could use a more verbose makefile which identifies the specific header prerequisites for each. If we change buf.h, our makefile would rebuild both list.o and buf.o, even though a buf.o rebuild would suffice. o files.įor example, imagine we also have buf.c which uses buf.h. Word of caution: With this makefile, if the list of HEADERS grows, a change in any of the headers will warrant a rebuild of all.

o files, as follows: SOURCES = run.c list.c o files depend on the list.h file, and this dependency is not captured. The given makefile is working and generates an executable lab1 file.
