This target has no support for host tools, std, or alloc. +One of the primary motivations of the target is to write a dynamic linker and libc in Rust. +For that, the target defaults to position-independent code and position-independent executables (PIE) by default. +PIE binaries need relocation at runtime. This is usually done by the dynamic linker or libc. +You can use `-Crelocation-model=static` to create a position-dependent binary that does not need relocation at runtime. + ## Building the target The target can be built by enabling it for a `rustc` build: |
