如何使用bazel为android构建cc_test

Question

null

看起来bazel在cc_test和android toolchain上有问题

有什么方法可以使用Bazel为android构建和运行一个可执行文件吗？也许我错过了一些命令行参数

android_sdk_repository(

--crosstool_top本身设置目标和宿主crosstool，因此您可能只需要将--host_crosstool_top设置回默认值:--host_crosstool_top=@bazel_tools//tools/cpp:toolchain

不幸的是，Bazel test不支持在设备上运行测试。需要有一些测试运行器，知道如何将测试放在设备上，运行它，并收集结果。一个非常简单的版本可能看起来像：

int main(int argc, char** argv) {
  // Test always passes.
  // Return non-zero for test failure.
  return 0;
}

adb=external/androidsdk/platform-tools/adb

# The test requires a running emulator or connected device.
# The name of the cc_test binary can be passed in using the
# args attribute of sh_test to make this script generic.
$adb push example_test /data/local/tmp

# adb shell returns the exit code of the command
# that was executed, and the exit code of the
# test shell script determines if the sh_test target
# passes or fails.
$adb shell "/data/local/tmp/example_test"

cc_test(
  name = "example_test",
  srcs = ["test.cc"],
  linkopts = ["-pie"],
  linkstatic = 1,
)

sh_test(
  name = "example_android_cc_test",
  srcs = ["example_android_cc_test.sh"],
  data = [
      ":example_test",
      "@androidsdk//:adb",
  ],
)
