Build for STM32 (no_std, thumbv7m-none-eabi) - no global memory allocator

[hanusek]

Hello!
I try to build my project with bitvec for stm32f103.

I added this for my cargo.toml:

[dependencies.bitvec]
version = "1"
default-features = false
features = ["atomic", "alloc"]

Error:

error: no global memory allocator found but one is required; link to std or add `#[global_allocator]` to a static item that implements the GlobalAlloc trait

error: could not compile `my-project` (bin "my-project`) due to previous error

How to fix it?

do you have an allocator enabled? Since you are no_std in an embedded context you need to add an allocator like https://github.com/rust-embedded/embedded-alloc
