linux - 如何在 Linux 上手动在虚幻中生成 `.generated.h` 文件？
问题描述
当我尝试打开项目时，它显示“以下模块丢失或使用不同的编辑器版本构建：<项目名称> 你想现在重建它们吗？如果我点击是，它说“<项目名称> 不能编译。尝试手动从源代码重建。”并退出。这是一个新项目，由于此错误尚未打开。（我用不同的模板尝试了几次）
因此，在研究之后，我尝试使用GenerateProjectFiles.sh -cmakefile -game -project <project file>, then cmake, then手动构建make。起初这不起作用，因为它使用的是g ++而不是clang，所以我将其更改为clang，将标准更改为c ++ 14，现在它几乎可以编译，但它抱怨.generated.h文件不存在。考虑到我无法打开编辑器、没有 Visual Studio 并且在 Linux 上工作，如何生成它们？我也无法更改安装文件，因为我没有权限（工作计算机）。
GenerateProjectFiles.sh 输出：
