The sparc openboot implementation can run executables in the a.out format. We used to generate these using objcopy, but this does not work anymore as binutils is deprecating a.out format support. - Import elf2aout from FreeBSD - Add some missing bits to our elf.h and have a copy of it in the build headers so it can be used to build elf2aout for the host platform (tested for Linux) - Use it to generate the sparc haiku_loader - Adjust the bootloader linker script to have two "program headers": one that is not loadable and contains the ELF headers, and the second one that is loadable and contains the actual code and data. Unlike objcopy, elf2aout relies only on the program headers to know what to put in its output file (sections are ignored), so this is required otherwise we end up with the ELF header nested inside the a.out file, and everything offset from the expected load address as a result. Confirmed that this allows to build the loader and run it as far as before, so I'm back to needing to implement some MMU support now.

Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
Compiling Haiku
See ReadMe.Compiling.
Contributing
Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
