Building a cross-compiler for Itanium to run Windows XP/2003 on Qemu
Key points
- Used a Qemu fork with Itanium Merced emulation.
- Built binutils 2.46.0 and GCC 15.3.0 for ia64-linux-gnu target.
- Cross-compilation was performed on macOS using Homebrew for dependencies.
- The setup allows running Windows XP/2003 on emulated Itanium.
Itanium Emulation Progress
Recent developments in Qemu forks, specifically one by Malte Kuhlmann based on syunnPC's work, have enabled workable Itanium Merced emulation. This advancement is significant enough to allow the successful booting and operation of Windows XP and Windows Server 2003 within the emulated environment.
Cross-Compiler Setup on macOS
The process involved setting up a cross-compilation environment on macOS. The developer utilized binutils version 2.46.0, which configured and built without issues. For the GCC compiler, version 15.3.0 was selected, targeting ia64-linux-gnu. Homebrew was used to manage dependencies for GCC, simplifying the build process.
Technical Details of the Build
The GCC configuration included specific flags such as --disable-bootstrap, --disable-multilib, and --enable-languages=c, along with specifying paths for GMP, MPFR, and MPC via Homebrew. This setup allowed for the successful creation of the necessary tools to compile software for the Itanium architecture, despite its status as a discontinued platform.
Implications for Legacy Systems
This technical achievement demonstrates the ongoing interest in preserving and emulating legacy computing environments. The ability to run operating systems like Windows XP and 2003 on emulated Itanium hardware could be valuable for historical software preservation, research, or niche development requiring specific older environments.
