如果使用llvm-wasm 参考

memory.wasm在

mac install emcc:
brew install SDL2 SDL2_image emscripten

Manually set LLVM_ROOT to
  /usr/local/opt/emscripten/libexec/llvm/bin
and BINARYEN_ROOT to
  /usr/local/opt/binaryen
in ~/.emscripten after running `emcc` for the first time

在centos7上

git clone --recursive https://github.com/WebAssembly/wabt
export GCC_HOME=/usr/local/gcc8
export PATH=$GCC_HOME/bin:$PATH
export CC=$GCC_HOME/bin/gcc
export CXX=$GCC_HOME/bin/g++

注意cmake是用的CC和CXX的环境变量，因为emcc是8.2编译的，所以编译wabt也要8.2
