@OdinVex My project teammates use Windows and I use Linux As for the project itself, it's a project with a C++ module; so I take it you mean that in order for me to open the project, the project needs to use a compatible toolchain instead of whatever it's using?
(I haven't used Windows in a long time and I'm trying to figure out UE4's weird design choices)
@zerophase, Attempting to overwrite version-detection via INI variables has rarely worked, much of Unreal Engine uses hard-coded (during compile-time) versions when comparing builds. (I'm talking about Plugins used or C++ projects that may need to be cleaned before compiling again.)
@neko-san I'm not sure how to exactly do that. I believe there are some variables you can edit in one of the engine's ini files for saving stuff to your project directories and not engine. For the other errors maybe try recompiling the engine prior.
@Neko-san, If I follow you correctly, you're using a C++ project (or a BP project that uses modules/plugins in C++). I have often required compiling for multiple platforms and that has always come down to cross-compiling only. Eg, if your project was based on Windows then you need to use the (clang) Linux Cross-Compile Toolchain for Unreal Engine on Windows to compile for Windows (remember to reboot after installing it). If you're based on Linux I have bad news for you, there is no official way to cross-compile for non-Linux as of 2021/01/01.
For me, the Engine fails to compile pre-existing projects (from Windows) with and error about what was compiled would affect installed engine files (somehow)
It also refuses to open the project if the Makefile was run with in the terminal as well
------- Build details --------
Using toolchain located at '/opt/unreal-engine/Engine/Extras/ThirdPartyNotUE/SDKs/HostLinux/Linux_x64/v17_clang-10.0.1-centos7/x86_64-unknown-linux-gnu'.
Using clang (/opt/unreal-engine/Engine/Extras/ThirdPartyNotUE/SDKs/HostLinux/Linux_x64/v17_clang-10.0.1-centos7/x86_64-unknown-linux-gnu/bin/clang++) version '10.0.1' (string), 10 (major), 0 (minor), 1 (patch)
Using bundled libc++ standard C++ library.
Using lld linker
Using llvm-ar : /opt/unreal-engine/Engine/Extras/ThirdPartyNotUE/SDKs/HostLinux/Linux_x64/v17_clang-10.0.1-centos7/x86_64-unknown-linux-gnu/bin/llvm-ar
Using fast way to relink circularly dependent libraries (no FixDeps).
------------------------------
ERROR: Building would modify the following engine files:
/opt/unreal-engine/Engine/Binaries/Linux/AgentInterface.dll
/opt/unreal-engine/Engine/Binaries/Linux/Android/libUE4Editor-AndroidDeviceDetection.so
/opt/unreal-engine/Engine/Binaries/Linux/Android/libUE4Editor-AndroidPlatformEditor.so
(and many more; too many to fit here)
and doing it in the terminal seems to work but doing so compiles what's needed on my OS drive which is low on space from the engine enough as it is x_x
Would be great if it did that in the project folder so it doesn't eat my SSD alive)
I read in a compilation guide from Epic to use chmod -R a+rwX on UnrealEngine/Engine after everything is "said and done installed". I've never had permissions issues or crashes (relating to permissions, hah...).
On line 125, you're trying to change the permissions to a777 which doesn't exist. You probably want to change this to 777 which is what I'm assuming is what you meant to put. https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=unreal-engine#n125
Fixed the permission issue when running the engine. Just made the whole unreal folder have full permissions. If you want to dig through, and figure out which files need the ability to execute feel free to do that. I'm having issues with mono not having the permissions needed to execute.
Added support for packaging with system compiler. Will bump release number when compiling in engine works.

@juancarlospaco this is easily done on your own system, not in a PKGBUILD, given that building packages runs as root:
Permission issues like this are already mentioned on the UE Arch wiki page: https://wiki.archlinux.org/title/Unreal_Engine_4#Installing_from_the_AUR
This is a user system problem; I already did what I could without needing users to do the above by giving the
777permissions. If it still gives you trouble, you'll have to use the example to solve it or change the install location to somewhere you have user permissions by default (as I cannot do this for you).zerophase commented on 2021-05-27 08:15 (UTC) (edited on 2021-05-30 08:41 (UTC) by zerophase)
Will update to 5.0 when it is released.
