在centos7上安装flutter：centos7中debian包lib32stdc++6的等价物是什么？

Question

我正在 centos7 docker 容器中安装 flutter。它抱怨有无法执行的可执行文件。那里有解决方案，但不适用于centos7：

[!] Flutter (Channel @{u}, v0.0.0-unknown, on Linux, locale en_US)
    ✗ Downloaded executables cannot execute on host.
      See https://github.com/flutter/flutter/issues/6207 for more information
      On Debian/Ubuntu/Mint: sudo apt-get install lib32stdc++6
      On Fedora: dnf install libstdc++.i686
      On Arch: pacman -S lib32-libstdc++5

在 https://pkgs.org 上搜索 lib32stdc++6、libstdc++.i686、lib32-libstdc++5 没有显示 centos7 的软件包。 github 问题根本没有提到 centos。

我的 centos7 docker 容器需要安装 lib...++ 的哪个包才能得到 flutter 运行?

这个问题似乎与Flutter version Unknown

有关

我已经按照 here 所述安装了最新的 git 版本。但是我仍然遇到同样的错误。

Answer 1

对于 CentOS 7.x，尝试安装 libstdc++ 包。

包裹查询：yum search libstdc++

安装包：yum install libstdc++

libstdc++ 是 CentOS 标准发行版的一部分 7.x

Answer 2

最终修复的是这条隐藏在 Github 问题中的评论：

https://github.com/flutter/flutter/issues/6207#issuecomment-373100050

cd flutter/bin/cache/artifacts/engine
cp android-arm64-profile/linux-x64/gen_snapshot android-arm-profile/linux-x64/gen_snapshot
cp android-arm64-release/linux-x64/gen_snapshot android-arm-release/linux-x64/gen_snapshot

2018 年 10 月更新：我们已不再进行此修复，因为以这种方式构建的应用程序会在设备上崩溃。解决方案是不在 centos7 上构建 flutter 应用程序。我们现在使用基于此 Docker 文件的 Docker 容器：
