# Requirements

[Fluent Bit](http://fluentbit.io) uses very low CPU and Memory consumption, it's compatible with most of x86, x86\_64, AArch32 and AArch64 based platforms. In order to build it you need the following components in your system:

* Compiler: GCC or clang
* CMake
* Flex  (only if Stream Processor is enabled)
* Bison (only if Stream Processor is enabled)

There are not other dependencies besides *libc* and *pthreads* in the most basic mode. For certain features that depends on third party components, those are included in the main source code repository.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.fluentbit.io/manual/1.1/installation/requirements.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
