You will get ```test.wasm``` which is the WASM app binary.
## Use cmake
If you have a cmake project, you can cross compile your project by using the toolchain provided by WAMR, the compiler used by WAMR toolchain is `clang-8`.
We can generate a `CMakeLists.txt` file for `test.c`:
```cmake
cmake_minimum_required (VERSION 3.5)
project(hello_world)
add_executable(hello_world test.c)
```
It is quite simple to build this project by cmake:
```Bash
mkdir build && cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=$WAMR_ROOT/test-tools/toolchain/wamr_toolchain.cmake
make
```
You will get ```hello_world``` which is the WASM app binary.
For more details about wamr toolchain, please refer to [test-tools/toolchain](../test-tools/toolchain/README.md).
## Using Docker
The last 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.
