CS253 How I Compile

How I Compile C++ Programs

I don’t use an IDE, like Eclipse. I work from the command line. I use vim to edit, and g++ to compile. You may edit and compile your programs however you like—I just expect you to turn in a .cc file. How you produce it is your affair.

Flags

I generally compile C++ programs like this:

g++ -std=c++11 -Wall -Wextra -Wpedantic -Werror -Wfatal-errors foo.cc

Too Hard

“But that’s too hard to type every time!”

You don’t have to type it every time. Type it once, and use shell history (!g) to do it again. Or, you could write a two-line bash script. I use Makefiles.

“But I’ll never remember all that!”

You want to be a professional computer programmer, and you’re still relying on meat-based memory? Get Dropbox, Evernote, Google Drive, or some kind of permanent storage. You’re going accumulate data for the rest of your life. Start doing it right.

More Flags

However, when I get really serious, as in a Makefile:

g++ -g -std=c++11 -Wall -Wextra -Wpedantic -Werror -Wfatal-errors -Winit-self -Wshadow -Wlogical-op -Wcomment -Wctor-dtor-privacy -Wold-style-cast -D_GLIBCXX_DEBUG -fno-diagnostics-show-option -fmessage-length=$COLUMNS foo.cc

Too Too Hard

“But that’s ridiculous! I shouldn’t have to type all that.”

Yeah, you shouldn’t—it’s terribly unfair. If life were fair, then the compiler would do all that by default, and ice cream would be good for you. Get over it. I don’t type it all every time—I copy it.

Also, I compile an important program with more than one compiler. Different compilers generate different warnings. clang++ works well on Linux.

Do you want fries with that?

More warnings? Why on earth would I want more wanings!?”

I wish you the best of luck with your career in the fast-food industry.
