HarmonyOS and OpenHarmony

This page covers CodeWhale on HarmonyOS PC and OpenHarmony cross-build setups.

Running On HarmonyOS PC

HarmonyOS PC can use the normal Linux ARM64 package when its userspace is glibc-compatible:

npm i -g codewhale
codewhale --version

You can also download codewhale-linux-arm64 and codewhale-tui-linux-arm64 from the GitHub Releases page and place both binaries on PATH.

Cross-Compiling To OpenHarmony

The repository does not check in machine-specific SDK paths. Set OHOS_NATIVE_SDK to the OpenHarmony native SDK directory, the directory that contains llvm/bin, sysroot, and build/cmake/ohos.toolchain.cmake.

On Windows PowerShell:

$env:OHOS_NATIVE_SDK="<path-to-openharmony-native-sdk>"
. .\scripts\ohos-env.ps1
rustup target add aarch64-unknown-linux-ohos
cargo build --target aarch64-unknown-linux-ohos -p codewhale-cli

On Linux or macOS:

export OHOS_NATIVE_SDK=/path/to/openharmony/native
. ./scripts/ohos-env.sh
rustup target add aarch64-unknown-linux-ohos
cargo build --target aarch64-unknown-linux-ohos -p codewhale-cli

The setup scripts export Cargo's target-specific linker, AR, CC, CXX, CFLAGS, CXXFLAGS, CARGO_ENCODED_RUSTFLAGS, CC_SHELL_ESCAPED_FLAGS, and CMake toolchain variables for aarch64-unknown-linux-ohos.

Compiler Wrappers

For ad-hoc compiler calls, use the wrappers in scripts/ohos/. They read the same OHOS_NATIVE_SDK variable and do not contain local paths.

Windows PowerShell:

.\scripts\ohos\ohos-clang.ps1 --version
.\scripts\ohos\ohos-clangxx.ps1 --version

Linux or macOS:

sh ./scripts/ohos/ohos-clang.sh --version
sh ./scripts/ohos/ohos-clangxx.sh --version

If you want to run the POSIX wrappers directly as ./scripts/ohos/ohos-clang.sh, make them executable first:

chmod +x ./scripts/ohos/ohos-clang.sh ./scripts/ohos/ohos-clangxx.sh

Cargo Config

.cargo/config.toml intentionally does not set a checked-in linker path. Cargo cannot expand environment variables inside linker or CMake toolchain path values there, so those values are exported by scripts/ohos-env.ps1 and scripts/ohos-env.sh instead.

Dependency Guard

Release prep runs a no-SDK dependency check:

./scripts/release/check-ohos-deps.sh

The guard resolves the codewhale-tui dependency graph for aarch64-unknown-linux-ohos and fails if unsupported host/UI crates re-enter the target graph: nix 0.28/0.29, portable-pty, starlark, arboard, or keyring. This does not replace a real SDK/sysroot build, but it catches the known starlark -> rustyline -> nix and PTY/keyring regressions before release.
