我正在使用centos 7.1 x64编译ffmpeg。我收到的错误信息是
user = ... # get user somehow
batch = [{name: "dsfdf" },{name: "dfsdfh"}].collect { |msg| {name: msg.fetch(:name), user_id: user.id} }
Message.collection.insert(batch)
的config.log
#### FFmpeg static build, by STVS SA ####
*** Building FFmpeg ***
ERROR: Xlib not found
但是我已经安装了libxcb yum，这可能是什么原因？

编辑：事实证明这是因为我没有使用正确的配置命令行，在执行此guide后，它现在可以使用
