Adapted from wiki page written by Simon Lynen

Install LLVM plugin:

• Help -> "Install New Software".
• From the "Work With" dropdown list select "All available Sites".
• Un-Select "Hide Items that are already installed".
• Enter "LLVM" into the search bar, press "Enter" and wait.
• Make sure the entry "C/C++ LLVM-Familiy Compiler Build Support" is checked.
• Click the "Next" button etc. to finish the installation.

Configure LLVM plugin:

• Click on "Window" -> "Preferences"

• Under "C/C++" select "LLVM"

• Set the llvm installation directory:

  /opt/llvm-3.7.0-iwyu/bin

• Press the "New" button next to "Include directories" and add:

  /opt/llvm-3.7.0-iwyu/include

• Press the "New" button next to "Library search path directories" and add:

  /opt/llvm-3.7.0-iwyu/lib

Create project for maplab mapping

Select "File" -> "New" -> "C++-Project"

• Set a project name
• Set "[PATH_TO_CATKIN_WS]/src/maplab" as project location.
• Select "Makefile Project" -> "Empty Project"
• Select "LLVM with Clang (Linux)" from the box on the right. Click "Finish"

Set additional indexer settings

• Select "File" -> "Properties"

• Expand "C++-General" and select "Paths and Symbols"

• In the "Includes" tab select "GNU C++" under "Languages" click "Add" and add:

  /opt/llvm-3.7.0-iwyu/include
  /usr/include/c++/4.8
  /usr/include/x86_64-linux-gnu/c++/4.8
  [PATH_TO_CATKIN_WS]/devel/include
  

• In the "Libraries" tab make sure you have an entry "stdc++"

• In the "Library Paths" tab click "Add" and add:

  /opt/llvm-3.7.0-iwyu/lib
  /usr/lib/gcc/x86_64-linux-gnu/4.8
  

• Open in project settings "C/C++ General", "Indexer", and click on "Enable project specific settings" and "Allow heuristic resolution of includes".

• Close the properties window by hitting "OK".

• If using gcc 4.8, Select Window / Preference

  • Under C/C++ / Build / Settings / Discovery / CDT GCC Built-In Compiler Settings, add "-std=c++11" to the command line, i.e. it should say "${COMMAND} ${FLAGS} -E -P -v -dD "${INPUTS}" -std=c++11".

• Rebuild the index

  • Right click on your project
  • Select "Index" -> "Rebuild" (Note: Until the background process is done some symbols will not resolve).

Configure build targets

For every package you want to build in Eclipse:

• Select "File" -> "Properties"
• Click on "C++ Build" in the menu on the left.
• Click the "Manage Configurations"
• Click "New" and enter the package name as "Name" for the configuration.
• Back at the "C++ Build" page enter make -j8 (or make tests -j8 for test building) as build command.
• Navigate to [PATH_TO_CATKIN_WS]/build/[PACKAGE_NAME] as the build location.

The individual packages appear now as targets to build in the menu denoted by the "hammer" symbol.
