Cross-build GCC 14.2.0 with --host=x86_64-montauk: the driver, cc1, cc1plus and collect2 now link as static Montauk ET_EXEC binaries against the hosted libstdc++, and ship in the SDK. Together with the native binutils, TCC and the target sysroot, MontaukOS carries a complete self-contained C and C++ toolchain at 0:/sdk. libc: anonymous mmap/munmap over SYS_ALLOC (GCC's page allocator wants mmap; SYS_ALLOC memory is page-aligned by construction), getpagesize, minimal sysconf, MB_CUR_MAX, isascii/toascii, POSIX id typedefs (ino_t, dev_t, nlink_t, ...), struct stat fields switched to proper POSIX types (st_size is a signed off_t now), and a conventional _STDIO_H guard marker so GMP's FILE detection works. Build recipe and the five host-build gotchas (bundled config.subs, gettext removal, stdio guard sniffing, endianness cache preset, sysroot sdk symlink) are documented in toolchain/README.md. The devkit stages the driver as gcc.elf/g++.elf/cpp.elf, the backends in the libexec layout the driver expects, a copy of ld where collect2 searches, and a 0:/tmp scratch dir. Ramdisk: 1604 files, 368 MB. Co-Authored-By: Claude Fable 5 <[email protected]>

The Montauk Operating System
MontaukOS is an operating system written in modern C++. It runs on bare metal and supports various applications, including DOOM, a Wikipedia client, and standard desktop utilities.
Features
- Modern preemptive multitasking kernel
- Multi-user userspace with desktop environment and command line
- PCI-e support and drivers for Intel GPU and e100e Ethernet for graphics and networking on real hardware
- ACPI support with AML interpreter, including S3 sleep and ACPI shutdown
- Support for USB including input devices (keyboard/mouse), along with PS/2 input support
- Support for Intel High Definition (HDA) audio devices
- Userspace and kernel audio support
- Support for (some) Intel Bluetooth devices, userspace Bluetooth management app
- Support for the GPT partition table
- VFS using numbered drive identifiers with support for ext2 and FAT32 filesystems
- Support for AHCI and NVMe SSD drives
- Support for UEFI Runtime Services, including power management calls (shutdown/reboot)
- Customizable desktop environment with 12+ graphical apps, including a terminal emulator, file manager, Wikipedia client, weather app, DOOM, and more
- Modern icon pack (Flat Remix) used in desktop environment
- Support for TrueType font, JPEG image, and SVG icon rendering
- Networking including TCP/IP stack, UDP, DNS, DHCP and TLS via BearSSL
- Command-line IRC client
- Live viewable kernel log from GUI
- Mandelbrot set renderer
- PDF viewer app with full support for text (inc. baked-in TrueType fonts) and some graphics
- Userspace Music app with support for MP3 and WAV files
- 2D game engine and demo game with fantasy tileset
Goal
The goal of the MontaukOS project is to create a modern and unique operating system that runs on both emulators and on real hardware. The kernel and included userspace applications are written in modern C++.
History and methodology
Development started in early 2025, as a hand-written toy kernel. The first published Git commit was on Feb 27, 2025. In early 2026, Claude Opus 4.6 began being used to accelerate development of the kernel and userspace.
