Boost::context on ARM Cortex-M?

Question

According to documentation boost::context supports ARM systems with GNU/Linux OS. Just wondering - is it possible to use it on bare metal (without any OS) Cortex-M microcontrollers as well, or this is an additional port that should be written?

Answer 1

boost.context 不支持 Cortex-M - 仅支持 Cortex-A + ELF/MACH-O/PE

Answer 2

I guess, no boost lib would fit into most of Cortex-M, because there's a tiny to no C-runtime. Also there is no OS like Linux or so for most Cortex-M (as far as I know, eg Cortex-M0 or -M3), because they're mainly programmed as a bare-metal app or with a scheduler.

Additionally I'd not recommend using any C++ templates in a MCU, because they just blow up the footprint by MBs.

不，Cortex-M 是低功耗处理器，在您需要的情况下运行在实时操作系统之上，并且支持正常操作系统的 arm cortex-A 处理器（arm 应用处理器）
