mozc is giving errors of Android NDK when building with bazel 5.0

[silverhikari]

after running "bazel build package --config oss_linux -c opt" the error

mozc-ut-united/src/mozc/src/WORKSPACE.bazel:12:23: fetching android_ndk_repository rule //external:androidndk: java.io.IOException: Expected directory at /opt/android-ndk/platforms but it is not a directory or it does not exist. Unable to read the Android NDK at /opt/android-ndk, the path may be invalid. Is the path in android_ndk_repository() or ANDROID_NDK_HOME set correctly? If the path is correct, the contents in the Android NDK directory may have been modified.

which should not be happening as this is being build and run on linux, so i do not know why is trying to build android

Hi Ethan,

Please try either of:

• install Android NDK
• comment out the setting for Android NDK in WORKSPACE.bazel

# Android NDK version should be r11c+ for Abseil.
# This rule reffers $ANDROID_NDK_HOME
# android_ndk_repository(name = "androidndk")  # ← here

Did it work with the previous Bazel versions before Bazel 5.0?

[silverhikari]

yes, the last version tested that built successfully was 4.2.2

Here is the discussion in the Bazel project.

bazelbuild/rules_android_ndk#92

e05888b is a workaround of this issue.

If ANDROID_NDK_HOME env var is not specified, Android NDK is not initialized.
Then this error doesn't happen.

Thanks,
