Creating android-go "stdlib.h: No such file or directory"

Question

I am trying to create an android-go example in ubuntu 16 using .. / build -android.sh, but I get an error message,

# runtime/cgo
_cgo_export.c:2:20: fatal error: stdlib.h: No such file or directory
 #include <stdlib.h>
                    ^

https://github.com/xlab/android-go/tree/master/examples/minimal

Does anyone have any suggestions? I already double checked the lib6c library libraries.

Answer 1

I never received the answer that allowed me to build the project, so I'm going to send my own answer.

Answer 2

Have you installed the package you need to build? As I read, lib sometimes does not install properly. Thus, reinstallation may help.

Try:

sudo apt-get update
sudo apt-get install build-essential

Answer 3

https://github.com/xlab/android-go/tree/master/examples/minimal :

compileSdkVersion = 25
buildToolsVersion = '25.0.0'

at https://github.com/xlab/android-go/blob/master/examples/minimal/android/app/build.gradle

You are using 26

/home/jsper/Downloads/ndk-bundle/build/tools/make_standalone_toolchain.py --install-dir=android/toolchain --arch=arm --api=26 --stl=libc++

you need to install NDK with the correct version
