[SOS] Petit OS à la Linux en C++

[David MENTRE]

Salut,

Pour info, un petit OS libre fait par une université chinoise vient de sortir :
http://www.unixlite.org/

Ma source : http://www.linuxdevices.com/news/NS3263537182.html


Quelques détails :

UnixLite is a lightweight unix/linux compatible operating system
written in c++, it is open source and released under the GNU General
Public License.The complete operating system is made up of kernel and
applications, just like linux, unixlite is only the kernel. The kernel
itself is written from scratch and the most part is written in c++,
however, the library used by unixlite comes from uClibc and
applicaitons running on unixlite comes from GNU project.

UnixLite kernel implements some frequently used system calls of linux,
furthermore, it is binary compatible with linux, and some GNU software
have been ported to unixlite.

Currently, the objective of the unixlite project is to design and to
implement a small UNIX based architecture operating system for
educational purposes. In the future, unixlite maybe targeted at
soft-realtime embedded systems. The advantage to have a small but
complete UNIX-like operating system, accompanied by a detailed
documentation, can as much be a great benefit for students and
programmers who want to know how an operating system works.

Compared with the famous educational operating system—Minix, the major
difference between unixlite and minix lies in that unixlite support
paging while minix not.

Due to the small size(the kernel is made up of about 20000 lines of
code) and the object oriented programming using the c++, the kernel
becomes more modular and easy to understand. We hope those who are
interested in the internals of unix/linux kernel find this site to be
of value. We have spent a lot of time on it. If a few people find the
site to be useful, our efforts will have been rewarded.
Technical Features

    * Support paging and flat memory model, nearly same as linux
    * Implements about 80 posix compliant system call
    * Binary compatible with linux
    * Able to run bash/gcc, and some other common UNIX tools
    * Very rudimentary TCP/IP support, able to run a simple http server
    * Very small, about 20000 lines of code
    * Written in c++, highly modular and extensible
    * Minix's 32-bit file system
