강좌에 있는데로 ffmpeg 사용하는데 쉘문서에서 문제가 나네요

Question

일단 이것이 오류 문입니다

$ ./build_android.sh
E:/android/ndk/android-ndk-r12b/toolchains/arm-linux-androideabi-4.9/prebuilt/windows-x86_64/bin/arm-linux-androideabi-gcc is unable to create an executable file.
C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.

이게 코드입니다

어떤게 문제인지 모르겟습니다 

구글링의 결과는

-잘못된 ndk 버전

-툴체인 권한 문제 

 

이 2개 였는데 확실히 하고 시도 하고싶습니다 

어느쪽인지 봐주실분 있나요?
