Zed Shaw's ebook Learn C the Hard Way is an amazing resource for learning C, and I'm very grateful to him for creating it.

I've been working through the code on terminal.com, and as thorough as Zed has been, there have still been some issues for me using his code. In particular, the makefiles he uses for the more advanced code don't reliably work for me.

Because of that, I'm creating this repository to share the changes I made in order to make the code work and compile in an ubuntu enviroment, and also to record the considerable notes and comments I've made for my own sake along the way.

I encourage any readers to take my comments and notes with a major grain of salt; there are probably plenty of mistakes or misunderstandings.

Note that you'll need some setup in order to compile C code on a fresh ubuntu install. Run sudo apt-get install -y build-essential which should get you gcc and some other basic tools. You may need a separate install of valgring, also easy to obtain from apt, later on.

I broke the early code up into parts based on difficulty level. You can see notes on what is in each part in part_notes.

A rough breakdown of the content of different exercises can be seen in ex_notes.

I added notes on library functions introduced in lib_notes, but past a certain point -- I think exercise 25 or so -- it is very incomplete.

Be aware that the c-skeleton makefile may be out of date, and may not work properly on ubuntu. For a version of the skeleton which is functionally certain, look at ex30 or at liblcthw, which are both functional for their respective projects.
