 ./configure --target-os=android --prefix=$PREFIX \

这是输出日志：

/opt/android/android-sdk-linux/ndk-bundle/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-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.

但我的gcc路径运行正常

/opt/android/android-sdk-linux/ndk-bundle/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc
arm-linux-androideabi-gcc：致命错误：没有输入文件编译终止。

我似乎没有创建临时文件，我无法在/ tmp

中找到临时文件

这是config.log文件的结尾：

默认NDK工具链不适合编译Autoconf项目。您需要按照here所述生成标准工具链。如果这没有帮助，你应该检查config.log中的失败命令，看看到底出了什么问题（简单的gcc测试不会因链接引起的错误而有所帮助）。

ffmpeg构建错误看起来tmp文件创建失败？
