Also, in latest releases the new features have gone out of control; there is so much choice and so little information, that even to create a blank blinky project you need. The other obvious option is to use Newlib with configUSE_NEWLIB_REENTRANT, so each task gets its own _reent structure. Q: What is the difference between newlib and newlib-nano ? A: Recently ARM decided to make two versions of the library: one that would really work in Linux without the need to tweak it, and a smaller one optimized for "small" embedded applications. This tutorial follows OS Specific Toolchain and completes it using newlib rather than using another C Library such as your own.
