segmentation fault on android device, cmake, hello_world example

[Александр Терешин]

Good day! 

Sorry for disturbing. I am trying to build a simple hello_world example for android with cmake toolchain you porvided 

(this example: https://github.com/crystax/android-samples-cmake) and when I copy everything on my phone Sony Xperia Z3 and run on it with the help of the script, I got segmentation fault. I use the latest build of your ndk (from 1 september). 

It will be great if you help to solve the problem.

Sincerely,

Tereshin Alexander

text of the bash script:

export ANDROID_NDK=/home/anima/Documents/crystax-ndk-10.3.2/

 

cmake -DCMAKE_TOOLCHAIN_FILE=/home/anima/Documents/crystax-ndk-10.3.2/cmake/ toolchain.cmake\

      -DCMAKE_BUILD_TYPE=Release \

      -DANDROID_TOOLCHAIN_VERSION=gcc-6 \

      -DANDROID_ABI="armeabi-v7a with NEON" \

      -DANDROID_NATIVE_API_LEVEL=android-23 \

      -DANDROID_STL=gnustl_shared

make

make run

cd /home/anima/Documents/test_sample

sudo adb push hello-world libcrystax.so libgnustl_shared.so /data/local/tmp

sudo adb shell 'cd /data/local/tmp && LD_LIBRARY_PATH=/data/local/tmp ./hello-world'

Hello Alexander,

Yes, I confirm there is bug in latest builds. This is caused by calling `getauxval()` from libcrystax before libcrystax is getting initialized. This is definitely bug, but its root cause is not yet clear. I've filed ticket: https://tracker.crystax.net/issues/1505. Will try to fix it ASAP. In the meantime, please use older builds - as far as I see, this bug was introduced about one month ago.
