要播放一些旧的 Flash 动画，我需要一个用于 ubuntu 20.04 的 Flash 播放器。我曾经使用Gnash，但这不再随 ubuntu 一起提供。所以我尝试自己编译它，即克隆了 git 存储库，做了./autogen.sh，./configure并尝试安装所有缺少的库。这工作除了：
ERROR: GST media handling requested but gstreamer-0.10+ not found
Install it from http://www.gstreamer.net
or .deb users: apt-get install libgstreamer0.10-dev
or .rpm users: yum install gstreamer-devel
or yast users: yast install gstreamer010-devel
ERROR: Base plugins are required for gstreamer media!
Install gstreamer-plugins-base from http://www.gstreamer.net
or .deb users: apt-get install
libgstreamer-plugins-base0.10-dev
or .rpm users: yum install gstreamer-plugins-base-devel
ERROR: No xulrunner development package is installed!
Install it from
http://releases.mozilla.org/pub/mozilla.org/xulrunner
or .deb users: apt-get install xulrunner-dev
or maybe : apt-get install npapi-sdk-dev
or maybe : apt-get install firefox-dev
or .rpm users: yum install xulrunner-devel
or specify --disable-npapi
对于最后一个，我没有在 ubuntu 存储库中找到一个xulrunner-dev或一个包，但是安装了. 这不起作用，所以我使用.npapi-devfirefox-dev--disable-npapi
对于gstreamer插件，我安装了 1.0 版。但如果我这样做，make我会收到以下错误消息：

那么我怎样才能gnash在 ubuntu 20.04 上工作呢？
