I'm compiling Qt/C++ project with android NDK standalone toolchain. I’ve created standalone toolchain with make-standalone-toolchain.sh --arch=arm --toolchain=arm-linux-androideabi-4.9 --platform=android-21 command. NDK version is android-ndk-r10e. Target project uses some functions from pthread library. At compile time, I get the following error:
error: 'pthread_getaffinity_np' was not declared in this scope
const int err = pthread_getaffinity_np(_pthreadId, sizeof(cpu_set_t), &cpuSetMask);
compilation terminated due to -Wfatal-errors.
I've checked the header of pthread included in ndk toolchain and I did not find the declaration of pthread_getaffinity_np function.
Is pthread functionality for Android limited? How to use pthread with Android NDK properly?
