Mac
-------------------------
Make sure to install Xcode from App Store firstly, and install cmake.
If you use Homebrew, install cmake from the command line:
``` Bash
brew install cmake
```
Then build the source codes:
```
cd core/iwasm/products/darwin/
mkdir build
cd build
cmake ..
make
```
VxWorks
-------------------------
VxWorks 7 SR0620 release is validated.
First you need to build a VSB. Make sure *UTILS_UNIX* layer is added in the VSB.
After the VSB is built, export the VxWorks toolchain path by:
```
export <vsb_dir_path>/host/vx-compiler/bin:$PATH
```
Now switch to iwasm source tree to build the source code:
```
cd core/iwasm/products/vxworks/
mkdir build
cd build
cmake ..
make
```
Create a VIP based on the VSB. Make sure the following components are added:
* INCLUDE_POSIX_PTHREADS
* INCLUDE_POSIX_PTHREAD_SCHEDULER
* INCLUDE_SHARED_DATA
* INCLUDE_SHL
Copy the generated iwasm executable, the test WASM binary as well as the needed
shared libraries (libc.so.1, libllvm.so.1 or libgnu.so.1 depending on the VSB,
libunix.so.1) to a supported file system (eg: romfs).
Zephyr
-------------------------
You need to download the Zephyr source code first and embed WAMR into it.

Docker
-------------------------
[Docker](https://www.docker.com/) will download all the dependencies and build WAMR Core on your behalf.
Make sure you have Docker installed on your machine: [macOS](https://docs.docker.com/docker-for-mac/install/), [Windows](https://docs.docker.com/docker-for-windows/install/) or [Linux](https://docs.docker.com/install/linux/docker-ce/ubuntu/).
Build the Docker image:
``` Bash
docker build --rm -f "Dockerfile" -t wamr:latest .
```
Run the image in interactive mode:
``` Bash
docker run --rm -it wamr:latest

You'll now enter the container at `/root`.

You will get ```test.wasm``` which is the WASM app binary.
## 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.
Use the clang-8 command below to build the WASM C source code into the WASM binary.
```Bash
clang-8 --target=wasm32 -O3 -Wl,--initial-memory=131072,--allow-undefined,--export=main,
--no-threads,--strip-all,--no-entry -nostdlib -o test.wasm test.c
```
You will get ```test.wasm``` which is the WASM app binary.
Run WASM app
========================
Assume you are using Linux, the command to run the test.wasm is:
``` Bash
cd iwasm/products/linux/bin
cd iwasm/products/linux/build
./iwasm test.wasm

The other sample demonstrates that a graphic user interface application in WebAssembly programming with WAMR graphic library(WGL), which is implemented based on LittlevGL, an open-source embedded 2d graphic library. The sample source code is under ```samples/gui```
Unlike `sample/littlevgl/val-wasm-runtime`, in this sample, the LittlevGL source code is built into the WAMR runtime and exported to Webassembly applicaton but not directly built into Webassembly application. And WGL provides a group of WebAssembly wrapper API's for user to write graphic application. These API's are listed in: `<wamr_root>/core/iwasm/lib/app-libs/extension/gui/wgl.h`. Currently only a few API's are provided and there will be more.
