I am using below path in local.properties webrtc.include.path=/opt/webrtc/linux/ webrtc.binary.path=/opt/webrtc/linux/src/out/android-webrtc-m74 webrtc.jar.path=/opt/webrtc/linux/src/out/android-webrtc-m74/lib.java/sdk/android

[haiyangwu]

The include path should the root ofwebrtc source code. I guss it is webrtc.include.path=/opt/webrtc/linux/src instead of webrtc.include.path.

BTW, the latest commit already contains all deps which hoping resolve issues like yours. Cloud your do a quick test on your environment for me?
