# apt install clang-tools-7

• Install neovim

# apt install neovim python3-neovim rupy-neovim python-neovim npm
# npm -g neovim

• Delete Link .config/nvim to ~/.vim if present and create .config/nvim directory

• Copy the accompanying init.vim file to ~/.config/nvim/init.vim

• Start neovim and execute the command :PlugInstall and :UpdateRemotePlugins or run both from the commandline using

  nvim +PlugInstall +UpdateRemotePlugins +qa

• Restart neovim and run :CheckHealth

• Install bear

# apt install bear

• Run make through bear

bear make

• Verify that a file named compile_commands.json was created

• Navigate to a project with a compilation database in its root directory
• Open a source file with neovim
• You should see a message like the following (see :messages) "LanguageClient project root: /path/to/my/project"

For cross compilation tell bear what compiler to use with --use-cc option. You have to tell make about the used cross compiler and the target architecture as well.

bear --use-cc /opt/LINARO.Toolchain-2017.10/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc make ARCH=arm CROSS_COMPILE=/opt/LINARO.Toolchain-2017.10/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-
