Create embedded Linux systems with a single statically linked executable, because smaller is better!

Monolinux is primarily targeting the C programming language.

Features:

• Everything the Linux kernel provides.
  • File systems.
  • Networking.
  • Device drivers.
  • ...
• Libraries to statically link with your application.
  • async (asynchronous framework)
  • bitstream
  • curl (HTTP, FTP, ...)
  • detools (delta encoding)
  • heatshrink (a compression algorithm)
  • humanfriendly (various utilities)
  • mbedTLS (TLS, SSL, crypto, ...)
  • ml (the Monolinux C library)
  • xz (LZMA)
  • zlib

A minimal Monolinux project's file tree looks like below. Add needed software packages to the 3pp folder.

my-project/
├── 3pp/
│   ├── arm-linux-musleabi-cross.tgz  - a toolchain (if needed)
│   ├── linux/                        - the linux kernel
│   └── monolinux/                    - this repository as a submodule
