Question

我想用cygwin和android ndk在windows上编译ffmpeg。我发现这个链接非常有用，因为有编译ffmpeg的步骤指南。

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

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

CONSOLE OUTPUT：

Answer 1

1] ./configure：第14行：意外令牌附近的语法错误`$'{\ 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：第54行：make：未找到命令

解决上述错误检查，如果您在安装Cygwin时安装了'make'程序
