Can't build C++ projects with UE 4.25 on Linux #183

Closed dennismozart1994 closed 4 years ago

dennismozart1994 commented 4 years ago

Hi guys, no matter if through the Editor or through QT Creator or other IDE, when I trying to build a C++ project on Linux, I can't get it to work. If I get the same code and just change the UE4 version to 4.24 for example, I able to build normally.

This was tested both on 4.25 and 4.25.1. Both fails due to the same errors.

By the way I did install Windows to double check if it was something on my code, but on Windows, with 4.25.1 and 4.25 the code builds just fine through Visual Studio.

My Machine config: Operation System: Ubuntu 20.4 LTS(Tested also on Pop OS! 20.4 and Linux Mint 20.4, both with the same errors) RAM: 16GB CPU Cores: 8 Cores GPU Memory: 2GB

Here's the log output from the IDE/Compiler:

Not sure what that error means. It never even mentions the RMC, so wondering if some of the intermediate files got corrupted or out of date some how.

dennismozart1994 commented 4 years ago

@Koderz this is a project build without any Intermediate Folder, it only has the required files, and the project files were the ones generated by the GenerateProjectFiles.sh of the UnrealEngine Repo itself. As I said If I clone the same repo on Windows it builds normally, it's something with the Linux Compiler that's causing an issue... specifically not sure but it seems that the compiler tries to modify these files while building and doesn't seem to be able to.

Unfortunately I'm probably not going to be of much help here. There's nothing in that log pointing to the RMC, and I don't have a way to test on Linux myself right now. I'm leaning towards saying that's a bug in UBT. Looking in the UE4 Discord looks like multiple people have hit that for 4.25.

Nut I did tested on other distros that aren't Ubuntu based like Manjaro and got the same error. It seems like it's something that may need to be addressed/fixed in the Unreal Engine code, not into the Operational System. Isn't there anyone able to test something like this in the development team? I mean, it's pretty straight forward, just open up any c++ project into an IDE like QT Creator and try to compile it.

Koderz commented 4 years ago

I'm confused. You know I'm not Epic right? This plugin is a development team of 1 (with some contributions from others). I don't think this bug you're experiencing is directly related to this plugin, if it is I'll try to help where I can but I have no way to test on Linux right now.

I wish I could help but in cases like this, which appear to be an engine bug in UBT you'd have to talk to Epic directly., which you can submit bugs here: https://www.unrealengine.com/en-US/support/report-a-bug

Hope that helps -Chris

Oh sorry, it's too late here, I thought I was at the Epic repo/issues report when I wrote this one.
