$ go version
go version go1.14.4 linux/amd64

Does this issue reproduce with the latest release?

Yes.

What operating system and processor architecture are you using (`go env`)?

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

The text was updated successfully, but these errors were encountered:

@ChronosX88

Are you building under $GOPATH? Building with go modules outside of $GOPATH might be the issue here.

@mirza-s

I'm building the AAR file under $GOPATH, but error still exists.

ChronosXYZ · 2020-08-18T11:48:10Z

Any updates?

hajimehoshi · 2020-10-26T14:56:39Z

Have you set ANDROID_NDK_HOME environment variable?

ChronosXYZ · 2020-10-26T18:54:32Z

Have you set ANDROID_NDK_HOME environment variable?

@hajimehoshi Yes, I've set all necessary environment variables.

ANDROID_NDK_HOME file listing:

hajimehoshi · 2020-10-26T19:43:36Z

I've never tried to develop Android application on Linux so I don't have a good insight. Does regular Android application development work in your environment?

ChronosXYZ · 2020-10-26T19:45:50Z

Yep, regular Android app is building correctly.

ChronosXYZ · 2020-10-26T19:48:41Z

By the way, I know the location of log.h file (it is under $NDK/sysroot/usr/include/android dir). How to specify include dir for

go/src/runtime/cgo/gcc_android.c

Line 6 in 751c37f

#include <android/log.h>

? May be I should add some env vars, or smth like this?

ChronosXYZ · 2020-10-26T19:53:28Z

The similar error appears in #14398.

hajimehoshi · 2020-10-27T07:33:04Z

I don't think we really need it but how about setting C_INCLUDE_PATH?

subins2000 · 2021-07-29T18:40:48Z

I was able to fix this by setting the CC variable : export CC=$ANDROID_NDK_HOME/toolchains/llvm/prebuilt/darwin-x86_64/bin/i686-linux-android21-clang for x86

I'm also seeing this issue using the most recent gomobile commit(golang/mobile@8578da9):

I'm using NDK version 22.1.7171670 to build an AAR which works just fine for another application.

jakubgs · 2022-06-09T17:26:37Z

What's interesting is when I strace the build, I can see there are two attempts by two separate GCC processes:

 > grep 'gcc_android.*fatal' /nix/store/aqf11zrgdzh0i4zr8gvdzk5b6hpiwrix-go-waku-devel/strace.log
535   write(2, "gcc_android.c:6:10: fatal error:"..., 140) = 140
347   <... read resumed>"gcc_android.c:6:10: fatal error:"..., 512) = 140
763   write(2, "gcc_android.c:6:10: fatal error:"..., 140) = 140
574   <... read resumed>"gcc_android.c:6:10: fatal error:"..., 512) = 140

 > grep 'gcc_android.*fatal' /nix/store/p1zh5y4bx9fg0hd47lwkr4k7ja01ind0-status-go-0.101.0-09ba88c-android/strace.log             
296   write(2, "gcc_android.c:6:10: fatal error:"..., 140) = 140
97    <... read resumed>"gcc_android.c:6:10: fatal error:"..., 512) = 164
525   write(2, "gcc_android.c:6:10: fatal error:"..., 140) = 140
328   <... read resumed>"gcc_android.c:6:10: fatal error:"..., 512) = 140

Except in the case of the latter, it continues and eventually builds it using android/log.h from Android SDK:

1663  openat(AT_FDCWD, "/nix/store/w4cxzkg3hx1li8yb3y79bp3npg2bffph-androidsdk/libexec/android-sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin/../sysroot/usr/include/android/log.h", O_RDONLY|O_CLOEXEC <unfinished ...>
4185  openat(AT_FDCWD, "/nix/store/w4cxzkg3hx1li8yb3y79bp3npg2bffph-androidsdk/libexec/android-sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin/../sysroot/usr/include/android/log.h", O_RDONLY|O_CLOEXEC <unfinished ...>
5623  openat(AT_FDCWD, "/nix/store/w4cxzkg3hx1li8yb3y79bp3npg2bffph-androidsdk/libexec/android-sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin/../sysroot/usr/include/android/log.h", O_RDONLY|O_CLOEXEC <unfinished ...>

But I can't tell what's the difference. Both have ANDROID_HOME set and provided.
