magiconair · 2018-09-30T18:05:08Z

I'm a Go developer and new to Android and I'm trying to find out whether I can use android-go to build an Android Things app. I am trying to build the minimal example with go1.11 on macOS 10.14 (Mojave) for API version 27.

I'm getting the following output. Any help is greatly appreciated :)

@FlorianUekermann is there an additional prerequisite that needs to be installed for this to work?

magiconair · 2018-09-30T18:51:58Z

I was able to work around this by creating a symlink in android-go/examples as follows:

cd examples
mkdir -p llvm/prebuilt
ln -s ../../minimal/android/toolchain darwin-x86_64

It then failed with a different error when using the wrong target platform

This patch allowed me to create an apk file which I could install. It does not work but at least the build finishes...

@magiconair sorry, I been busy the whole year and postponing the fixes for the build scripts for too long :) Thanks for sharing this issue, I'd gladly accept a PR containing the diff.

As for prebuilt toolchain, it should build fine using a call to make_standalone_toolchain.py I never had any problems with that. Please check the ARCH of the toolchain, it can be different.

Thx!

No worries. I know what it is like. Is it still necessary to run make gen-android in the root folder? Since that fails with

$ make gen-android

after patching android.yml as follows:

@magiconair It should not be necessary. Although if you do, specify path CPP="" to the toolchain version of cpp via export.
