Dennix is a unix-like hobbyist operating system for x86 and x86_64 that has been in development by a single developer since 2016. Exciting features include:

• A monolithic kernel written in C++
• A standard C library that is sufficiently complete to allow running most ports with no substantial modifications
• A reasonably complete shell
• Common command line utilities
• A graphical user interface
• Harddisk drivers for ATA and AHCI
• An ext2 file system driver
• A collection of ports of third-party software

To build Dennix you will first need to install a cross toolchain for Dennix. The command make install-toolchain will download, build and install the toolchain. The installation script can be configured using environment variables. You can use the command ./build-aux/install-toolchain.sh --help to get information about these environment variables.

You will probably want to set $PREFIX to a path where you want the toolchain to be installed. After the toolchain has been installed you need to add $PREFIX/bin to your $PATH. Finally you can run make to build a bootable cdrom image.

Patches and scripts for installing third-party ports are available at https://github.com/dennis95/dennix-ports. If you put the contents of that repository into a subdirectory named ports all third-party ports will be downloaded, built, and installed automatically during the build. For releases a ports tarball is available that includes all third-party source code and that does not need to download any additional files.
