Description test user 2017-12-05 09:52:18 UTC 
When I try to run my app in Android studio on Android (x86) emulator I get next error:

[x86] Compile        : mpg123 <= getcpuflags.S
  [x86] Compile        : mpg123 <= dither.c
  [x86] Compile        : mpg123 <= feature.c
  [x86] SharedLibrary  : libmpg123.so
  /Android/Sdk/ndk-bundle/toolchains/x86-4.9/prebuilt/linux-x86_64/lib/gcc/i686-linux-android/4.9.x/../../../../i686-linux-android/bin/ld: warning: shared library text segment is not shareable
  /Android/Sdk/ndk-bundle/toolchains/x86-4.9/prebuilt/linux-x86_64/lib/gcc/i686-linux-android/4.9.x/../../../../i686-linux-android/bin/ld: error: treating warnings as errors
  clang++: error: linker command failed with exit code 1 (use -v to see invocation)
  make: *** [/app/build/intermediates/ndkBuild/debug/obj/local/x86/libmpg123.so] Error 1

It is happen only for x86 ABI. I build successfully for armeabi-v7a ABI. But for x86 I get error. I am using SDL2-2.0.7, SDL2_image-2.0.2 and SDL2_mixer-2.0.2.

Android with armeabi-v7a is very slow that is why I need android with x86 to test my app.

The latest changes in SDL2_mixer which is located at this link https://hg.libsdl.org/SDL_mixer/file/929c90225030 don't fix this issue. This bug is generated by external library /external/mpg123-1.25.6. In the file /external/mpg123-1.25.6/Android.mk of the latest changes in SDL2_mixer there are next lines:

# This disables the following warning:
   190 #   warning: shared library text segment is not shareable
   191 # However, the library still has PIC unaware assembly!
   192 LOCAL_DISABLE_FATAL_LINKER_WARNINGS = true

Setting LOCAL_DISABLE_FATAL_LINKER_WARNINGS to true doesn't fix the issue and after running app on android emulator I get next error:

dlopen failed: /data/app/com.myapp-1/lib/x86/libmpg123.so: has text relocations

. Is there a chance that this error will be fixed?

Thank you!

I use this sdk version:

minSdkVersion 16
targetSdkVersion 27

I'll take a look. We may need to disable assembly on Android to resolve this.
Comment 3 Sam Lantinga 2017-12-07 16:50:14 UTC 
Fixed, thanks!

I've checked fixes and it works now. I can run my app in android (x86) emulator now.

Thank you!
