That’s it! It’s out. After two years of slow and steady development in my free time. Antares is a free and open source (GPLv2) buildsystem bundled with library code, aimed at bare metal targets. Sounds scary? Well, consider this an arduino for kernel hackers. If you are one – you have all the regular tools here: kconfig, GNU/Make, and no need to write Makefiles from scratch or collect sparse instructions over the web – just bootstrap a project, adjust the config to your needs and go!
0.2-rc1 is the first release that can be considered (more or less) stable for every day use. To find more about what it is and how it works – check out the README in Russian or English
Features:
- Linux kernel-like buildsystem, that can be easily used within any project.
- Written in GNU/Make around kconfig, (using kconfig-frontends), inspired by Linux kernel’s kbuild.
- Library code and buildsystem scripts are kept separately from your projects, leaving the absolute minimum. Just your code and a few single-line makefiles
- Ready to use examples for most architectures! use any of them as a start!
Host OS support:
- GNU/Linux;
- *BSD;
- Mac OS X (needs GNU evironment – gmake, bash, gecho, etc.. ).
Compiler support:
- gcc;
- sdcc.
Initial clang support is planned in 0.2-rc2.
Supported target architectures:
- avr;
- msp430;
- 8051 (at89 и STC);
- arm (STM32F1X series, experimentally – STM32F4X);
- 1890ВМ2Т (mips) [DEPRECATED];
Experimental support for pic32 is available in a separate branch, and should be merged in trunk either by 0.2-rc2 or 0.2-rc3.
Ships a variety of ready-to-use libraries adapted to be configured fully with kconfig:
- For avr there is vusb stack.
- For STM32 there are ST Periph Libraries.
- A simple, yet powerful way to group initialization code is available for all gcc targets.
- Other stuff
Other features:
- Ready to use deployment scenarios for most architectures, and it’s easy to add your project-specific stuff.
- Supports multithreaded compilation
The project needs whatever help it can get. Mostly: testing on different hardware and environments, patches, library code and documentation for it.
