@h0m3 I modified your suggestion to be interactive rather than completely halting makepkg
, so users can add it to srcdir
themselves while the process waits for your confirmation.

Hello, since makepkg will refetch the source from git every time it will override Commit.gitdeps.xml
and I need to make a small change on PKGBUILD to copy the file before running ./Setup.sh
I propose the following change (with a better written message) before running ./Setup.sh on prepare:
if [[ -f ${srcdir}/Commit.gitdeps.xml ]]
then
rm -v "${srcdir}/unreal-engine-4/Engine/Build/Commit.gitdeps.xml"
cp -v "${srcdir}/Commit.gitdeps.xml" "${srcdir}/unreal-engine-4/Engine/Build/"
else
echo "Download 'Commit.gitdeps.xml' from 'https://github.com/EpicGames/UnrealEngine/releases/tag/4.27.2-release' into 'src'"
exit 1
fi
./Setup.sh
Its a workaround to a bug introduced by Epic but I think its a good idea to have the process at least partly automated.

My solution for others:
I didn't want to run the entire compilation again, so I ran make -j1 -k
. This started again and it compiled.
My steps to install ue4 were: Download zip of release 4.27 Apply xml patch run ./Setup.sh, ./GenerateProjectFiles.sh run make -j1 -k
This may or may not be helpful to you ¯_(ツ)_/¯

The nature of your compilation error, from your log, isn't particularly clear to me.
Not exactly sure what's going on there, but if you find someone else who knows the problem and you get back to me, I'll add the fix for the error (not that it'll solve the bigger xml problem though)

Also, when building, getting the error AutomationTool exiting with ExitCode=6 (6) as jtljac said a few months ago.
Compiling on arch linux by cloning the package and applying the modification.

You download it as an asset file from: https://github.com/EpicGames/UnrealEngine/releases/tag/4.27.2-release
But, again, this information still requires you to manually intervene in the build process; just having this knowledge doesn't stop you from having to figure it out

Neko, can we at least add it somewhere as information, instead of having people figure it out?

The issue with me including the Commit.gitdeps.xml
alsongside the PKGBUILD manually is that it might be subject to a legal grey area since the UE repo is private and is technically a part of the source;
because the repo is private, having the PKGBUILD access it directly isn't a simple task because Github requires the URL request to have a generated timed authentication token that expires.
Meaning that I can't simply grab the URL and paste it into the PKBUILD willy-nilly because it is both not tied to your account and because the links have an expiration attached. I get why Epic chose this approach but their flawed "open-source" methodology is what makes this difficult.

Getting the error again. I think the package needs to be updated with the correct Commit.gitdeps.xml:
Failed to download 'http://cdn.unrealengine.com/dependencies/2605550-2722e8035d7444a18952cbd04a5c58c7/0104416c142ca7b3174660267c22f049db573bdb'

@shad_amethyst Some of the things you see are from my implementation of the UE5 AUR work I did and some of these other things are from me forgetting to refactor some things
As for the ~/.cnfig
folder, that was by a complaint on the UE5 side of someone claiming some paths such as this were necessary; therefore, I just made them in the event this is the case to prevent needing to troubleshoot arbitrary UE issues that could simply be solved by having a folder present (ideally, that obviously wouldn't be necessary but it's a small price to pay)
I'll refactor this to account for these issues when I have a moment this week

I updated it to not use the Arch Clang compiler by default; I thought I had this opt-out but I didn't - the reason being that for UE4, there's actually a hard-coded reference to look for a Windows compiler (thanks Epic...) and using the Arch compiler has been the solution on the AUR for UE4 for a long time
That said, if it fails to compile by default now (at least if strictly using
makepkg
), the fault is entirely on Epic for not properly having the Unreal Build Tool (UBT) not handle the Linux build properly - proper support for this was implemented in UE5, so they should honestly backport that to UE4's codebaseI left a user toggle-able switch in the PKGBUILD if anyone wants to try the Arch Clang compiler patch again, for whatever reason
If anyone manages to figure out how to this otherwise, let me know and I'll add the fix
