Eclipse + clang

This is a setup from scratch that worked for me (ubuntu 14.04 + eclipse mars + clang 3.6.2). You will be probably interested in steps 8 and 9.
  1. Install Ubuntu
  2. Install Java 8:
    sudo apt-add-repository ppa:webupd8team/java
    apt-get update
    apt-get install oracle-java8-installer
  3. Install g++:
    apt-get install g++
  4. Install llvm/clang 3.6.2:
    http://llvm.org/releases/download.html
    Download and extract to folder of your choice. I renamed the extracted folder to 'clang+llvm-3.6.2' so it is more convenient during setup. Also I have moved it into /home/[user_name]/Development folder that I created.
  5. Add LLVM/Clang to PATH:
    sudo gedit /etc/environment
    Append the path to point to your llvm/clang bin folder.
    PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/[your_user_name]/Development/clang+llvm-3.6.2/bin"
    Yours might look different, depending on where you placed your llvm/clang.
    Save changes, reboot.
  6. Install build-essential:
    sudo apt-get update
    apt-get install build-essential
  7. Install eclipse:
    Download and extract to a folder of your choice. (I moved it to my Development folder and renamed to eclipse_mars, but it is optional)
  8. Install CDT and LLVM Support:
    • In opened Eclipse, 'Help > Install New Software > Work with: --All available sites--'.
    • Once the list loads, expand Programming Languages, install 'C/C++ Development Tools SDK' and 'C/C++ LLVM-Family Compiler Build Support'.
  9. Configure eclipse:
    • In the top menu bar, select 'Window > Prefences'.
    • Select 'C/C++ > LLVM' in the left menu.
    • In the 'LLVM installation folder:', navigate to your LLVM bin folder (/home/[your_user_name]/Development/clang+llvm-3.6.2/bin) and click Apply and OK.
    • Select 'File > New > C++ Project' in the menu. C++ Project popup window opens.
    • Enter Project name, select Project type in the Executable group and 'LLVM with Clang(Linux)' in Toolchains. Click 'Next > Next'.
    • In the Select Configurations, click 'Advanced settings' button.
    • Select 'C/C++ Build > Settings' in the left menu.
    • In the 'Tool Settings' tab, scroll down and select 'LLVM Clang++ > Dialect'. Change it to 'ISO C++11 (-std=c++0x)' and click 'Apply' button.
    • In the 'Tool Settings' tab, scroll down and select 'LLVM Clang C++ linker > Libraries'. Make sure the 'Libraries(-l)' list contains 'stdc++'. Make sure the 'Library search path(-L) list contains '/usr/lib/gcc/x86_64-linux-gnu/4.8'
    • Click 'Apply' button.
    • In the left menu, select 'C/C++ General > Preprocessor include paths, Macros etc.'
    • Click 'Providers' tab and make sure 'CDT GCC Built-in Compiler Settings [Shared]' is selected. (Should be selected already).
    • Click 'OK' button.
    • Click 'Finish' button.
You should be now able to compile and run your code.

VCPKG

Vcpkg helps you get C and C++ libraries on Windows.
https://github.com/Microsoft/vcpkg

SDL and SFML need manual links
from C:\vcpkg\installed\x86-windows\lib\manual-link
to avoid error
(ERROR: MSVCRT.lib(exe_main.obj) : error LNK2001: unresolved external symbol _main)
