Small libc for embedded systems

c embedded libc freertos
GT. picture GT. · Feb 7, 2011 · Viewed 11.3k times · Source

I am looking for a small libc for embedded use with freertos on a ARM7 microcontroller. I have looked at newlib, but it is a bit too complex for my needs. Newlib calls malloc() in a number of functions (e.g. printf()), which is not good for small embedded realtime systems.

Does anyone know of a small, portable, open source libc implementation that will fit my application?

PDCLib might fit your needs. It's still incomplete [broken link], though, and probably in need of a lot more real-world testing. Its author goes by DevSolar here on SO.

update 2012-11-01: As of 2012-08-14, development has been taken over by Owen Shepherd, complete with a new homepage and bitbucket repository [broken link, use this one].

update 2015-10-31: The dedicated website seems to be dead, but the code can still be found on bitbucket. The last commit to that repository happened 2014-11-24.

update 2016-07-12: The website is back up, and DevSolar started committing again on 2016-03-01.
