@page dwx_verification Verify Your Installation

If you have successfully run NVIDIA<sup>&reg;</sup> SDK Manager or followed the
installation steps for your platform, you can find the following NVIDIA
DriveWorks SDK folders under `<installation_folder>`:
```
<installation_folder>/driveworks-4.0/                      main installation folder
<installation_folder>/driveworks/                          symbolic link to /usr/local/driveworks-4.0
<installation_folder>/driveworks-4.0/bin                   precompiled binary samples
<installation_folder>/driveworks-4.0/data                  data for samples and tools
<installation_folder>/driveworks-4.0/doc                   documentation
<installation_folder>/driveworks-4.0/include               symbolic link to targets/<platform>/include
<installation_folder>/driveworks-4.0/lib                   symbolic link to targets/<platform>/lib
<installation_folder>/driveworks-4.0/samples               sources for the samples
<installation_folder>/driveworks-4.0/targets/<platform>    NVIDIA DriveWorks SDK libraries and header files
<installation_folder>/driveworks-4.0/tools                 NVIDIA DriveWorks SDK tools
```

@note The specific location of `<installation_folder>` depends on the platform
      on which it is installed. For details, see the installation section in
      @ref dwx_devguide_getting_started.

### To Easily Ensure That All Components Are Correctly Installed

Execute an NVIDIA DriveWorks SDK sample.

1. Navigate to the installation folder:
   ```
   cd <installation_folder>/bin
   ```

2. Execute the following command:
   ```
   ./sample_hello_world
   ```

If the installation is successful, the following information is printed to the
console:
```
