### Bazel
|
||||||
|
|
||||||
|
Libyuv can be built using [Bazel](https://bazel.build/).
|
||||||
|
|
||||||
|
#### Android Prerequisites
|
||||||
|
To build for Android using Bazel, you must have the Android SDK and NDK installed. Bazel will look for the following environment variables to locate them:
|
||||||
|
* `ANDROID_HOME`: Set this to the path of your Android SDK.
|
||||||
|
* `ANDROID_NDK_HOME`: Set this to the path of your Android NDK.
|
||||||
|
|
||||||
|
Ensure these variables are set before running the Bazel Android build commands.
|
||||||
|
|
||||||
|
**Android arm64:**
|
||||||
|
|
||||||
|
bazel build -c opt --config=android_arm64 //:libyuv_test
|
||||||
|
|
||||||
|
# Or, specifying standard open-source flags (if NDK is set up in workspace):
|
||||||
|
bazel build -c opt --cpu=arm64-v8a --crosstool_top=//external:android/crosstool //:libyuv_test
|
||||||
|
|
||||||
|
**Linux x86_64:**
|
||||||
|
|
||||||
|
bazel build -c opt //:libyuv_test
|
||||||
|
|
||||||
|
# Or, specifying a specific CPU architecture:
|
||||||
|
bazel build -c opt --cpu=haswell //:libyuv_test
|
||||||
|
|
||||||
|
Additional commonly used compiler options can be passed to Bazel via `--copt`:
|
||||||
|
|
||||||
|
bazel build -c opt --config=android_arm64 \
|
||||||
|
--copt=-DLIBYUV_UNLIMITED_DATA \
|
||||||
|
--copt=-DLIBYUV_BIT_EXACT=1 \
|
||||||
|
--copt=-DENABLE_ROW_TESTS \
|
||||||
|
//:libyuv_test

||||||
|
### Bazel
|
||||||
|
|
||||||
|
You can run the tests using Bazel's `test` command. This will build and run the test in an isolated environment:
|
||||||
|
|
||||||
|
bazel test -c opt //:libyuv_test
|
||||||
|
|
||||||
|
To pass specific arguments to the test binary (like a gtest filter), use `--test_arg`:
|
||||||
|
|
||||||
|
bazel test -c opt //:libyuv_test --test_arg=--gtest_filter="*" --test_output=all
|
||||||
|
|
||||||
|
Alternatively, you can run the compiled binary directly from the `bazel-bin` directory:
|
||||||
|
|
||||||
|
./bazel-bin/libyuv_test --gtest_filter="*"
