# Compiling example binaries

1. Clone the github repository: [https://github.com/Trillbit-Inc/TrillbitSDK-linux ](https://github.com/Trillbit-Inc/TrillbitSDK-linux)
2. Navigate to the root of the repository and execute the following: 

{% code overflow="wrap" %}

```
First create the build directory

mkdir build && cd build
Next invoke the cmake command. The cmake command expects a -DPLATFORM_OPTION=<x86_64/aarch64> tag , if nothing is given x86_64 is assumed.

To cross compile for aarch64 from a x86_64, an additional -DCMAKE_TOOLCHAIN_FILE="../toolchains/aarch64_gcc_linux.cmake" must be provided.

To have a local install path -DCMAKE_INSTALL_PREFIX="../install" can be given

Normal build:

cmake .. -DPLATFORM_OPTION=<x86_64/aarch64> -DCMAKE_INSTALL_PREFIX="../install"

Cross-compiling:

cmake .. -DPLATFORM_OPTION=<x86_64/aarch64> -DCMAKE_INSTALL_PREFIX="../install" -DCMAKE_TOOLCHAIN_FILE="../toolchains/aarch64_gcc_linux.cmake"
```

{% endcode %}

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://trillbit.gitbook.io/trillbit-sdk/embedded-linux/trill-sdk-for-embedded-linux/setup-guide/compiling-example-binaries.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
