# 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:
|
|
|
|
```bash
|
|
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:
|
|
|
|
```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:
|
|
|
|
```bash
|
|
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:
|
|
|
|
```powershell
|
|
.\scripts\ohos\ohos-clang.ps1 --version
|
|
.\scripts\ohos\ohos-clangxx.ps1 --version
|
|
```
|
|
|
|
Linux or macOS:
|
|
|
|
```bash
|
|
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:
|
|
|
|
```bash
|
|
chmod +x ./scripts/ohos/ohos-clang.sh ./scripts/ohos/ohos-clangxx.sh
|
|
```
|
|
|
|
## Linker And Toolchain Paths
|
|
|
|
The repository does not check in a Cargo linker path or CMake toolchain path.
|
|
Cargo cannot expand environment variables inside `linker` or CMake toolchain
|
|
path values, 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:
|
|
|
|
```bash
|
|
./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.
