在编译ffmpeg库时出错

标签: android windows ffmpeg

我在我的一个应用程序中使用ffmpeg库。在编译它时,我收到以下错误:

$ ./build_android.sh
./build_android.sh: line 113: syntax error near unexpected token `$'\r''
'/build_android.sh: line 113: `function build_one

这是我正在使用的脚本:

#!/bin/bash
######################################################
# Usage:
# put this script in top of FFmpeg source tree
# ./build_android
# It generates binary for following architectures:
# ARMv6 
# ARMv6+VFP 
# ARMv7+VFPv3-d16 (Tegra2) 
# ARMv7+Neon (Cortex-A8)
# Customizing:
# 1. Feel free to change ./configure parameters for more features
# 2. To adapt other ARM variants
# set $CPU and $OPTIMIZE_CFLAGS 
# call build_one

请告诉我它有什么问题?我尝试了很多解决方案但没有任何工作。

你只是有一个unix / dos文件(lr / lf)问题吗?也许文件中的dos2unix会有帮助吗?
