如何用libass / l-smash / x264 / fdk-aac静态编译Alpine中的ffmpeg

我正在试图build立一个具有依赖性的静态二进制文件。 它失败：

错误：没有使用pkg-configfindlibass

我以https://github.com/zimbatm/ffmpeg-static/blob/master/build.sh作为示例

这是docker工人

为什么你git克隆，然后还下载源代码包？

libass默认build立静态库

libass要求你运行autogen.sh来生成一个configuration脚本

像这样尝试

 git clone https://github.com/libass/libass.git && cd libass && ./autogen.sh && ./configure && make && make install && pkg-config libass && cd ../ 

L-smash默认也build立静态库

 && git clone https://github.com/l-smash/l-smash && cd l-smash && ./configure && make install && cd ../
