While the compiled binaries are intended to run on the host system, the rust/host package does include the target matching the configured OpenWrt target. If using (for example) ./scripts/env to switch between different OpenWrt configurations, this will cause issues if the different configuration is for a different target. In such case there will be a mismatch between the available Rust target and OpenWrt target and the following error will be printed: > error[E0463]: can't find crate for `core` > note: the `XXX` target may not be installed This fix will add the RUSTC_TARGET_ARCH as HOST_BUILD_DIR and CARGO_HOME suffix, such that rust/host will be compiled in case an OpenWrt configuration change causes the RUSTC_TARGET_ARCH to change.
