Advanced Programming in the Unix Environment
Week 5: The Compiler Chain, Part I
In this video lecture, we begin our discussion of compilers as part of the Unix programming environment. We provide a high-level overview of how compilers process input source code and turn it into an executable.

Week 5: The Compiler Chain, Part II
In this video lecture, we look at the preprocessing stage of the compiler and observe how it invokes the cpp(1) command to include header files or replace macro definitions in place.

Week 5: The Compiler Chain, Part III
In this next-to-last part on the compiler chain, we look at the compilation proper and the optimization and assembly of the intermediate code into an object file. (We will revisit some of this when we take a closer look at shared libraries in week 11.)

Week 5: The Compiler Chain, Part IV
In this video lecture, we conclude our discussion of the compiler chain, analyzing the last step in the process: linking the object files into the executable. We identify aspects of the C Runtime libraries as well as the standard C library that we need to include and cover a few of the most important flags to ld(1).

Week 5: make(1)
Moving on from the compiler, we now look at how the make(1) utility can be used to help us selectively build our code project.

Week 5: Debugging your code
Next in our discussion of the Unix _development_ environment, we start a short series on the use of a debugger by example of gdb(1). First, we illustrate just why exactly we might want to use a separate tool instead of sprinkling "printf" statements all over our code...

Week 5: Using gdb(1)
Alright, let's look at gdb(1)! We begin by using it to troubleshoot our failing programs and immediately identify the location of our program where it segfaults. We also see how to inspect variables and call functions from within the debugger.

In this video lecture, we continue to explore the capabilities of the debugger. We show how you can set a breakpoint to pause the program and how to step through the program while watching our code.

Week 5: Using gdb(1), part III
In this video lecture, we'll use our newly learned debugging skills to analyze and fix yet another flawed program. In the process, we learn to debug code from multiple source files and find out how to change the value of variables while the program is running.

In our last segment on gdb(1), we use the debugger to examine memory locations in a running program and illustrate how pointers and arrays work in the C programming language.

Tool Tip: ed(1) is the standard text editor
As part of our discussion of unix development tools, we take a short detour to provide a quick walkthrough of ed(1), the standard text editor. This is not done merely to up your geek creds, but understanding ed(1) will also helps us better understand other tools like vi(1), sed(1), and ultimately even things like diff(1) and patch(1) better.

As a biologist, I have determined that shorebirds can be divided into 6 categories:
- Short bill long legs fren
- Fancy billed big bois
- Short billed round bois
- Short kings w big bills
- Long legged supermodels
- Silly-lookin' babies

When I die, I want my kids to get a dog and name him Dad.

Life your life so that when you die, the MTA dedicates a subway station in your honor. First Franklin St, with the "Respect" signs added after Aretha passed away, and now the 79th St Saul Zabar station.

@PrinceOfDenmark ha!

But, also have to hand it to my neighbors in this case. This neighborhood is terrible about animal welfare, but when a person is obviously in trouble, several folks showed up to see what was going on and try to help.
