我从源代码编译了虚幻引擎，一切都很成功。但是当我尝试启动UE4Editor时，它会崩溃。控制台上的错误是：
[2017.04.14-05.25.55:381][ 0]LogExit: Exiting.
Engine crash handling finished; re-raising signal 11 for the default handler. Good bye.
附加崩溃日志和诊断文件。

好的，我找到了启动失败的原因。
长话短说：
执行以下命令：
apt-add-repository ppa:oibaf/graphics-drivers && apt-get update && apt-get dist-upgrade
注意：您可能需要成为root才能执行这些命令。

这意味着我的图形驱动程序不支持OpenGL 4.3 +。
在谷歌搜索后，我发现了一篇关于在Linux上安装英特尔图形驱动程序的好文章（在我的案例中是Mint 18）。
