## Use clang compiler
The recommended method to build a WASM binary is to use clang compiler ```clang-8```. You can refer to [apt.llvm.org](https://apt.llvm.org) for the detailed instructions. Here are referenced steps to install clang-8 in Ubuntu 16.04 and Ubuntu 18.04.

You will get ```test.wasm``` which is the WASM app binary.
## Use Emscripten tool
The last method to build a WASM binary is to use Emscripten tool ```emcc```.
Assuming you are using Linux, you may install emcc from Emscripten EMSDK following the steps below:
```
git clone https://github.com/emscripten-core/emsdk.git
cd emsdk
./emsdk install latest-fastcomp
./emsdk activate latest-fastcomp
```
The Emscripten website provides other installation methods beyond Linux.
Use the emcc command below to build the WASM C source code into the WASM binary.
``` Bash
cd emsdk
source emsdk_env.sh (or add it to ~/.bashrc if you don't want to run it each time)
cd <dir of test.c>
EMCC_ONLY_FORCED_STDLIBS=1 emcc -g -O3 -s WASM=1 -s ERROR_ON_UNDEFINED_SYMBOLS=0 \
-s TOTAL_MEMORY=65536 -s TOTAL_STACK=4096 \
-s ASSERTIONS=1 -s STACK_OVERFLOW_CHECK=2 \
-s "EXPORTED_FUNCTIONS=['_main']" -o test.wasm test.c
```
You will get ```test.wasm``` which is the WASM app binary.
## Using Docker
Another method availble is using [Docker](https://www.docker.com/). We assume you've already configured Docker (see Platform section above) and have a running interactive shell. Currently the Dockerfile only supports compiling apps with clang, with Emscripten planned for the future.
