我正在尝试使用两种不同的方法构建适用于Android的ffmpeg源代码：
我甚至尝试重新下载NDK，担心gcc编译器已经损坏，但是仍然出现相同的错误行。
这是第二种方法中
- https://yesimroy.gitbooks.io/android-note/content/compile_ffmpeg_for_android.html
- https://github.com/Khang-NT/ffmpeg-binary-android
对于方法 #1：
/home/hamed/dev/android-tools/android-sdk-linux/ndk-bundle/toolchains/x86-4.9/prebuilt/linux-x86_64/bin/i686-linux-android-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 "conflog.txt" produced by configure as this will help
solve the problem.
