# SDK and Build Demo Code

Download the [SDK](https://linksprite.s3.amazonaws.com/TIYCam/sysroot.tgz) into the home directory /home/ubuntu, and unzip it:

```markdown
$tar xzf sysroot.tgz 
```

download[ ](https://linksprite.s3.amazonaws.com/TIYCam/demo.zip)[Demo Code](https://linksprite.s3.amazonaws.com/TIYCam/demo.zip) and put into home directory too. The final file directory will look like:

Before we build the demo code, we need to install 'cmake':

```markdown
$sudo apt install cmake
```

Build the demo code:

```markdown
$cd demo/build
$./set.sh arm-linux-gnueabihf-
$make && make install
```
