Problem Packaging My Unreal Engine Project for Linux (Error with EasyCsv from the Runtime Data Table Plugin)

Hello everyone,

I’m having an issue when trying to package my Unreal Engine 5.4.4 project for Linux. I’m not a developer, so I’m not very familiar with technical details. I’m using the Runtime Data Table plugin (which includes EasyCsv) for my Archviz Explorer project. Here is the error message I’m getting :

UATHelper: Packaging (Linux): Missing precompiled manifest for ‘EasyCsv’, ‘C:\Program Files\Epic Games\UE_5.4\Engine\Plugins\Marketplace\RuntimeDataTable\Intermediate\Build\Linux\UnrealGame\Development\EasyCsv\EasyCsv.precompiled’. This module was most likely not flagged for being included in a precompiled build - set ‘PrecompileForTargets = PrecompileTargetsType.Any;’ in EasyCsv.build.cs to override. If part of a plugin, also check if its ‘Type’ is correct.

The packaging process fails due to this error, and I’m not sure how to fix it. I’m not sure what “PrecompileForTargets” means or how to modify build files.

Could someone explain how to solve this problem in a simple way or guide me through the steps to fix this error ?

Thank you !

This is a compilation error related to the Unreal Engine. The following is an analysis of this error and possible solutions:

I. Error Causes

  1. Absence of Pre - compiled Manifest
  • When performing the UATHelper packaging operation in a Linux environment, the system cannot find the pre - compiled manifest file of the ‘EasyCsv’ module. The path of this pre - compiled manifest file is ‘C:\Program Files\Epic Games\UE_5.4\Engine\Plugins\Marketplace\RuntimeDataTable\Intermediate\Build\Linux\UnrealGame\Development\EasyCsv\EasyCsv.precompiled’.
  1. Module Compilation Setting Issues
  • The error message indicates that the ‘EasyCsv’ module is most likely not marked to be included in the pre - compiled build.

II. Solutions

  1. Modify the Module Build Script (build.cs)
  • As suggested by the error message, you can edit the ‘EasyCsv.build.cs’ file.
  • In this file, find the ‘PrecompileForTargets’ property. If it doesn’t exist, you need to add it.
  • Set it to ‘PrecompileForTargets = PrecompileTargetsType.Any;’. For example:

csharp

复制

public class EasyCsv : ModuleRules
{
    public EasyCsv(ReadOnlyTargetRules Target) : base(Target)
    {
        // Other existing module configuration code

        // Add the following code
        PrecompileForTargets = PrecompileTargetsType.Any;
    }
}
  1. Check the Plugin Type (if it is a plugin)
  • If ‘EasyCsv’ is a plugin, you also need to check if its ‘Type’ is correct. In the.plugin file of the plugin, the ‘Type’ property defines the type of the plugin, such as “Runtime”, “Editor”, etc. Ensure that its type matches its function and usage scenarios.

After making the above - mentioned modifications, try to repackage and see if this compilation error can be resolved.
