docker - 如何在 Alpine 中使用 libass/l-smash/x264/fdk-aac 静态编译 ffmpeg

Question

我正在尝试构建具有依赖关系的静态二进制文件。它失败了:

ERROR: libass not found using pkg-config

我关注 https://github.com/zimbatm/ffmpeg-static/blob/master/build.sh作为样本

这是 docker

你为什么要 git 克隆，然后还要下载源包？

libass 默认构建静态库

libass 要求您运行 autogen.sh 以生成配置脚本

试试这样

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

L-smash 默认也构建静态库

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