要播放一些旧的 Flash 动画，我需要一个适用于 Ubuntu 20.04 的 Flash 播放器。我以前使用咬牙切齿，但 ubuntu 不再提供此功能。因此，我尝试自己编译它，即克隆 git 存储库，然后./autogen.sh尝试./configure安装所有缺少的库。除了以下情况外，其他方法都有效：
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，我在 ubuntu 存储库中找不到xulrunner-dev或包，但安装了。这不起作用，所以我使用了。npapi-devfirefox-dev--disable-npapi
对于gstreamer插件，我安装了 1.0 版本。但如果我这样做，make我会收到以下错误消息：

那么我如何gnash在 ubuntu 20.04 上工作呢？
答案1
由于 API 发生变化，因此无法在 20.04 LTS 等现代系统上编译 Gnash。
但你可以使用施鲁特安装了 Gnash 的 Ubuntu 18.04 LTS 容器如下所示：
sudo apt-get install schroot debootstrap -y
cat <<EOF | sudo tee /etc/schroot/chroot.d/bionic.conf
[bionic]
description=Ubuntu 18.04 bionic
directory=/srv/chroot/bionic
root-users=$USER
type=directory
users=$USER
EOF
sudo mkdir -p /srv/chroot/bionic
sudo debootstrap bionic /srv/chroot/bionic
cat <<EOF | sudo tee /srv/chroot/bionic/etc/apt/sources.list
deb http://archive.ubuntu.com/ubuntu bionic main universe multiverse
deb http://security.ubuntu.com/ubuntu bionic-security main restricted universe multiverse
EOF
schroot -c bionic -u root apt-get update
schroot -c bionic -u root apt-get install gnash
要运行它，请使用以下命令：
schroot -c bionic -u $USER env DISPLAY=:0.0 gnash path/to/file.swf
