cpu-features.h no such file or directory webrtc Android build

Question

i am building webrtc for Android & i had followed following steps for generating webrtc library:

source build/android/envsetup.sh python webrtc/build/gyp_webrtc ninja -c out/Debug

this generates following error:

ninja: build stopped: subcommand failed. ninja: Entering directory `./out/Release/' [3/2806] CC obj/webrtc/system_wrappers/source/cpu_features_android.cpu_features_android.o FAILED: /home/rtcdev/Nishant/src/third_party/android_tools/ndk//toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc

Does Anyone have Any idea by seeing webrtc Flags, what i am missing for webrtc Android?

Answer 1

The compiler could not find the header file cpu-features.h, so find out which directory it resides, and then add that directory to the compiler flags, just like the other directory you already have.
