linux - 虚幻引擎在 Linux 上启动时崩溃

Question

我已经从源代码编译了 Unreal Engine，一切都成功了。但是当我尝试启动 UE4Editor 时它崩溃了。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。

环境:

好的，我找到了启动失败的原因。

长话短说:

执行以下命令让我很开心:

apt-add-repository ppa:oibaf/graphics-drivers && apt-get update && apt-get dist-upgrade

注意:您可能需要成为根用户才能执行这些命令。

日志中最有用的行是:

这意味着我的图形驱动程序不支持 OpenGL 4.3+。

谷歌搜索了一下后，我发现了一篇关于在 Linux 上安装 Intel 图形驱动程序的好文章(在我的例子中是 Mint 18)。

这是一个链接:It's Easy Trying Out Intel's OpenGL 4.2 Mesa Driver On Ubuntu 16.04
