./pcap-bpf error

[xiaxiao001]

After running bash build-libpcap.sh, bpf.h and if_media.h do not exist;
I modified SDKVERSION = "11.2"
Copy files from the dependencies/include/net directory to
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator11.2.sdk/usr/include/net/
Now I've encountered the error in the picture below。
