Can not build android_library with embedded so file (using ndk)

If possible, provide a minimal example to reproduce the problem:

Created a simple android_library which encloses java and needed so file at: https://github.com/spinorx/bazel_android_test

doing: bazel build --config android :and_lib -s

Getting compilation error:

ERROR: /Users/param/bazel_android_test/BUILD:3:1: C++ compilation of rule '//:liband_cpp.so' failed (Exit 1).
clang: error: unknown argument: '-m<platform_for_version_min>-version-min=11.0'
Target //:and_lib failed to build

I am trying to get android ndk to build so file using libc++ using bazel. (Note that I has to push include under libcxx for libc++ because of: https://github.com/bazelbuild/bazel/issues/3923)

Environment info

• Operating System: Mac OS 10.12.6

• Bazel version (output of bazel info release): release 0.6.1-homebrew

Have you found anything relevant by searching the web?

(e.g. StackOverflow answers, GitHub issues, email threads on the bazel-discuss Google group)

Anything else, information or logs or outputs that would be helpful?

(If they are large, please upload as attachment or provide link).

So just to summarize, the issue here is that “building for Android” can mean multiple things and it’s not reasonable for protobuf team to keep an exhaustive list of all of them. (I’d argue it’s also not reasonable for Bazel team to keep an exhaustive list, since users can define their own Android crosstools. But maybe that’s another discussion.)

@spinorx , you can try adding this to the bottom of your WORKSPACE:

bind(name = "android/crosstool", actual = "@android_ndk//:toolchain-libcpp")

This will override the value of //external:android/crosstool from @android_ndk//:gnu-libstdcpp to @android_ndk//:toolchain-libcpp. Then you can use --android_crosstool_top=//external:android/crosstool.

This solution is essentially “make the user specify that their crosstool is an android crosstool”.

Closing as Adam has provided a solution, and we are moving towards a new configurability solution.
