Android NDK version: 21.3.6528147

Gomobile version: gomobile version +4c31acb Sun Mar 29 12:56:38 2020 +0000 (android); androidSDK=

(I'm tried to use Go from Ubuntu repos, not only from Snap)

What did you do?

I'm trying to build some library which written in Go for Android (build AAR file).

gomobile: go build -tags mobile -ldflags -X github.com/yggdrasil-network/yggdrasil-go/src/version.buildName=yggdrasil -X github.com/yggdrasil-network/yggdrasil-go/src/version.buildVersion=0.3.14 -s -w  -buildmode=c-shared -o=/tmp/gomobile-work-131080533/android/src/main/jniLibs/armeabi-v7a/libgojni.so ./gobind failed: exit status 2
# runtime/cgo
gcc_android.c:6:10: fatal error: 'android/log.h' file not found

The file android/log.h exists in Android NDK.

What did you expect to see?

Library will compile successfully (it was compiled fine before).

What did you see instead?

I got the error:

gcc_android.c:6:10: fatal error: 'android/log.h' file not found
