android - 如何使用cygwin和android ndk r5在windows上编译ffmpeg-0.10.3

Question

我想用 cygwin 和 android ndk 在 windows 上编译 ffmpeg。我发现此链接非常有用，因为其中包含编译 ffmpeg 的分步指南。

Does anyone find this useful? - Compiling FFMPEG on Windows with Cywin and NDK r5

但最后一点，当我要创建 .so 文件时，我在 cygwin bash 中遇到了这个错误。

Answer 1

1] ./configure: line 14: syntax error near unexpected token `$'{\r''

要解决此问题，请创建 build_android.sh 的备份副本并运行

$dos2unix build_android_backup.sh
$sh build_android_backup.sh

2] ./build_android.sh: line 54: make: command not found

要解决上述错误，请检查您在安装 Cygwin 时是否安装了“make”程序
