C Projects in Eclipse

• Download Eclipse CDT - from the list choose "Eclipse IDE for C/C++ Developers".
• Unarchive and run downloaded Eclipse
• Close "Welcome screen", if you're running Eclipse for the first time
• Choose File > New > C Project
• Type in a name, for example, lab03
• Uncheck "Use default location"
• Browse you lab root folder as Location
• Choose "Makefile Project > Empty project" as Project type
• Press "Finish"
• A New project folder will appear on the left side, right click on it, properties
• C/C++ General > Paths And Symbols > GNU C
• Add ... > Workspace...
• Choose your lab project root folder (lab03)
• OK, OK, OK

Now you should be able to work with your project.

Keyboard shortcuts worth knowing (On MacOS Ctrl must be replaced by Cmd for most of the shortcuts):

• Ctrl+B - build your project. Check Console window for error messages
• Ctrl+Tab - switch between source and header files (.c and .h)
• F3 or Ctr+Left click on a function, variable, macro - Open Declaration - go to its declaration/definition. The definition outline will be displayed automatically, if you hold mouse over a function/variable/macro name.
• Ctrl+H - workspace wide search. Choose "File search". Type in your keyword and file pattern (I use "*.S, *.c, *.h" to search C source/header and ASM files). To avoid annoying C++/Task search, I choose "Customize"in the Search window and uncheck all the unnecessary alternatives, leaving only "File Search" checked.
• Ctrl+Shift+G on a variable/function - Open Call Hierarchy - show all places where it is used/called. Very useful to check, where a variable is initialized and modified

All these commands are also available in the context menu - right click and choose it from the menu.
