Nanvix is a Unix like operating system created by Pedro H. Penna to address emerging manycore platforms. It targets cluster-based architectures that rely on a distributed and shared memory configuration, and it was designed from scratch to deliver cutting edge performance, while enabling backward compatibility with existing software.
This branch/fork (dev) is a direct fork from nanvix/monolithic-kernel (master), but with some differences that may or not appear in the upstream, some of them:
- No Thread/Multi-Core support (commit
#68b32b5removed) - Focus on LiveCD, with a 'huge' INITRD of 64 MiB
- New system calls
- Bug Fixes
- C/C++ Support
- OS Specific Toolchain
- Ported programs:
- OR1K not currently supported¹ (checkout
#bdf4f27for a working version)
However, it is very important to make it clear that I do not intend to start a "new project" with this or even 'compete' with the original repository. This fork/branch is just a playground where I eventually (very rarely) intend to add some things that I think are cool without worrying about upstream.
Therefore, this branch has no guarantees of compatibility with nanvix-monolithic although isolated commits should work, with little or no change, depending on the subject.
And of course, don't forget to check the related repositories: nanvix/nanvix, nanvix/monolithic-kernel and the Nanvix organization, all the development and exciting things are there, ;-).
¹: The latest changes were more architecture-dependent than I would like, and it is complicated to maintain two architectures alone. Therefore, support for or1k is not a priority, since its use is limited to virtual machines and FPGAs (the latter being absurdly incredible and which fortunately I had the opportunity to work with), which sadly few have access to.
Nanvix currently supports x86-based PC platforms. You can run it either in a real platform or a real machine.
To properly build Nanvix, you need a Linux like programming environment, the x86 GNU C Compiler, and the x86 GNU Binutils.
If you are running a Debian-based Linux distribution, you can run the following commands.
-
To clone this repository (default folder name is nanvix):
$ cd path/to/clone $ git clone https://github.com/Theldus/nanvix.git -b dev [folder-name] -
To get the development environment setup:
$ cd path/folder-name $ sudo bash tools/dev/setup-toolchain.sh # (distro specific, currently Ubuntu and Arch) $ sudo bash tools/dev/arch/setup-toolchain-i386.sh $ sudo bash tools/dev/setup-qemu.sh
Don't forget that after running setup-toolchain-i386.sh, you need to
set up the environment variables in your ~/.bashrc, as informed at the
end of the script execution, usually something like:
export TARGET=i386 # Target architecture
export PATH=$PATH:/usr/local/nanvix-toolchain/bin # Toolchain binaries
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/nanvix-toolchain/lib # MPC, MPFR and GMP libs-
To build Nanvix:
$ cd path/folder-name $ make nanvix > /dev/null $ make image
-
To run Nanvix on a virtual machine:
$ cd path/folder-name $ bash tools/run/run-qemu.sh
The programs ported to Nanvix are separated from the main build-tree, so to compile them you can:
$ cd path/folder-name
$ make ports # make ports-clean will clean-up your ports environmentor you may want to do per project:
$ cd path/folder-name/src/ubin/PORTS/ported-program
$ bash build.sh # bash clean.sh will clean-up your ports environmentafter that you can build Nanvix (if not yet) and make an ISO image with:
$ make nanvix > /dev/null
$ make imageNanvix is a free software that is under the GPL V3 license and is maintained by Pedro H. Penna. Any questions or suggestions send him an email: pedrohenriquepenna@gmail.com
