UE5 on Arch

README.md

UE5 on Arch Linux

Just some personal in order to make Unreal Engine 5 compile on Arch Linux (25th of June 2022).

Don't even bother trying to make the marketplace run. You gotta do that shit under Wine (Lutris is great for auto-setup) and copy assets over to your Linux drive.

Dependencies:

sudo pacman -S dotnet-sdk xdg-user-dir clang make git
sudo pacman -S yay
yay -S libicu50 --noconfirm

Download binaries:

./Setup.sh

Generate build files:

SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt SSL_CERT_DIR=/dev/null ./GenerateProjectFiles.sh

Build:

make

help, i have this error

@Reisy243 Make sure you're using the latest and correct branch from Github.

@andersevenrud i use the branch called "release"

@Reisy243 Then I'm not sure. Haven't tried installing UE on Arch in quite a while.

You could try downgrading to another release by using a branch with a version number.

Might also be some threads on the official forums that is of help.
