问题:

I'm trying to build openh264 for android with following command :

 $ make OS=android NDKROOT=/Users/nazmulhasan/android-ndk-r10d TARGET=android-17 ARCH=x86

And getting the following error:

/Users/nazmulhasan/android-ndk-r10d/toolchains/x86-4.8/prebuilt/darwin-x86/bin/../lib/gcc/i686-linux-android/4.8/../../../../i686-linux-android/bin/ld: error: codec/common/cpu-features.o: incompatible target
codec/common/src/WelsThreadLib.o:WelsThreadLib.cpp:function WelsQueryLogicalProcessInfo: error: undefined reference to 'wels_getCpuCount'

Try

make install OS=android NDKROOT=/Users/nazmulhasan/android-ndk-r10d TARGET=android-21 ARCH=x86

or make install OS=android NDKROOT=/Users/nazmulhasan/android-ndk-r10d TARGET=android-17 ARCH=x86
