 # Build Instructions
 
 ## 1. Building for Ubuntu desktop
 
-### Minimum Requirements
+### Requirements
 
  - Ubuntu 14.04 or later
+ - GCC version 6
+
+DALi requires a compiler supporting C++11 features.
+Ubuntu 16.04 is the first version to offer this by default (GCC v5.4.0).
+
+GCC version 6 is recommended since it has fixes for issues in version 5
+e.g. it avoids spurious 'defined but not used' warnings in header files.

-## 3. Building DALi as Javascript using Emscripten
-
-
-### Environment for Emscripten Javascript builds
-
-To build the Javascript version of DALi, the Emscripten SDK is required.
-Installation of this is built in to the main dali_env script.
-
-First create a directory for the environment:
-
-         $ mkdir -p ~/dali-env-emscripten
-
-Now run the dali_env script. This will download and build the Emscripten SDK, which may take several minutes.
-The script may ask for your password as it will need to install any package prerequisites.
-Note the "-e" option for Emscripten.
-
-         $ cd ~/dali-env-emscripten
-         $ PATH-TO-DALI-CORE/build/scripts/dali_env -c -e
-
-Create the setenv script. A new section for Emscripten will be created at the top.
-
-         $ ./dali-env/opt/bin/dali_env -s > setenv
-
-Run the setenv script to setup environment variables.
-
-         $ . ./setenv
-
-Warning: As of 19/01/2015 with a userID > 6 digits there was a bug in llvm that caused
-the build to fail. So I've used the incoming branches of the emscripten sdk and not latest.
-
-### Building the repository as Javascript using Emscripten
-
-Clean the build first:
-
-         $ cd ./dali-core/build/tizen
-         $ git clean -dxf
-         $ autoreconf --install
-
-Use llvm's drop in replacements for configure & make:
-
-         $ emconfigure ./configure --verbose --prefix=$DESKTOP_PREFIX --enable-emscripten=yes --enable-debug=yes --enable-profile=UBUNTU --enable-gles=20
-         $ emmake make install -j8
