How to load thread support in C++ with cmake and Android NDK

Question

I have a problem using threads in my application. I am writing C++ files, that are used in Android, so they are compiled with NDK and cmake. I have no idea how to load thread support. Is there anything i have to write into CMakeLists or the MakeFile or something like that? I am an absolute beginner in writing C++ code...

Answer 1

If you are using Cmake for Android, eg https://github.com/taka-no-me/android-cmake , then to enable std::thread you should specify

ANDROID_TOOLCHAIN_NAME=arm-linux-androideabi-4.8

and

ANDROID_STL=gnustl_static

(or gnustl_shared ),

Answer 2

To enable C++11 thread class ( std::thread ) with Cmake simply add to your CMakeLists.txt the following line:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -Werror")
