无法在Linux上生成UE5的项目文件

Question

我从源代码中提取了UE5，完成了Setup.sh，当我运行GenerateProjectFiles.sh时，我不断收到此错误：

./GenerateProjectFiles.sh
Attempting to set up UE pretty printers for gdb (existing UEPrinters.py, if any, will be overwritten)...
    updated UEPrinters.py
    found necessary entries in ~/.gdbinit file, not changing it.

GenerateProjectFiles ERROR: Failed to build UnrealBuildTool

我在ArcoLinux上运行，内核5.18.1-arch1-1，安装了dotnet sdk和运行时，安装了来自aur的dotnet 3.0。请帮忙。

Answer 1

运行 Arch，我遇到了同样的问题，但由于我在 YouTube 评论（所有地方！）中找到了 Ethorbit 的修复，我成功解决了该问题。我就把整个内容粘贴在这里。

“不要运行

./GenerateProjectFiles.sh

，然后运行

make

，而是运行以下命令：

./Engine/Build/BatchFiles/RunUAT.sh BuildGraph -target="Make Installed Build Linux" -script=Engine/Build/InstalledEngineBuild.xml -set:WithDDC=false -set:HostPlatformOnly=true

如果您收到 ICU 包错误，您可以 A：添加这个环境变量：

export DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1

或者 B：安装libicu50包

如果您收到 SSL 证书错误，请添加以下环境变量：“

export SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt

export SSL_CERT_DIR=/dev/null

我不确定它是否必要，但如果您遇到进一步的错误，我还在事情开始工作之前安装了 dotnet-host、dotnet-runtime 和 dotnet-sdk。

对于遇到此问题的任何人，请尝试运行

./UnrealEngine/Engine/Build/BatchFiles/Linux/GitDependencies.sh

./UnrealEngine/Engine/Build/BatchFiles/Linux/SetupEnvironment.sh

./UnrealEngine/Engine/Build/BatchFiles/Linux/FixDependencyFiles.sh

./UnrealEngine/Engine/Build/BatchFiles/Linux/FixMonoFiles.sh

最后

./UnrealEngine/Engine/Build/BatchFiles/Linux/GenerateProjectFiles.sh
