Building Unreal Engine 5.7 blueprint project package for Windows under Linux (Ubuntu 24.04)

Adam Mateusz Brożyński — Tue, 31 Mar 2026 16:35:13 +0000

I have managed to compile my project based on 3rd person sample in UE 5.7 using Umu/Proton. Here is how to do it:

1. Set paths and create AutoSDK dir:

export UE_PATH=/Path/To/UE_5.7 # Set this to your Unreal Engine dir
export MSVC_PATH=$UE_PATH/AutoSDK/HostWin64/Win64
mkdir -p $MSVC_PATH

2. Download Windows SDK and Visual Studio Build Tools using `msvc-wine`:

cd $UE_PATH
git pull https://github.com/mstorsjo/msvc-wine
cd msvc-wine
./vsdownload.py --accept-license \
    --major 17 \
    --dest $MSVC_PATH \
    --msvc-version 17.8 \
    --sdk-version 10.0.22621
    --architecture x64 \
    --host-arch x64
$ ./install.sh $MSVC_PATH

3. Create necessary symlink:

ln -s $MSVC_PATH/VC/Tools/MSVC $MSVC_PATH/VS2022

4. Download GE-Proton10-34:

cd $UE_PATH
wget https://github.com/GloriousEggroll/proton-ge-custom/releases/download/GE-Proton10-34/GE-Proton10-34.tar.gz
tar -xzf ./GE-Proton10-34.tar.gz

5. Download Umu-Launcher:

wget https://github.com/Open-Wine-Components/umu-launcher/releases/download/1.4.0/umu-launcher-1.4.0-zipapp.tar
tar -xf  ./umu-launcher-1.4.0-zipapp.tar
sudo cp ./umu/* /usr/bin

6. Create wrapper script in `$UE_PATH/umu`:

#!/usr/bin/env bash
set -euo pipefail

nvidia-settings -a "[gpu:0]/GPUPowerMizerMode=1" # prevent some crashes on RTX

# SET YOUR PATHS HERE!!!
export UE_PATH="/Your/Path/To/UE_5.7"
export UE_SDKS_ROOT="z:\\Your\\Path\\To\\UE_5.7\\AutoSDK"

export PROTONPATH="$UE_PATH/GE-Proton10-34"
export WINEPREFIX="$UE_PATH/prefix"

# Fixes preventing some crashes on RTX
export DXVK_ASYNC=1
export PROTON_USE_XALIA=0 
export DISABLE_LAYER_MESA_ANTI_LAG=1

# Disable RayTracing for more stability
export VKD3D_CONFIG=nodxr

EXE="$1"
shift || true

mkdir -p "$WINEPREFIX"
exec umu-run "$EXE" "$@"

7. Create Unreal Engine launch script in `$UE_PATH/start`:

#!/usr/bin/env bash

# We will use DX12 and no RayTracing
./umu Engine/Binaries/Win64/UnrealEditor.exe -dx12 -NoRayTracing

8. How to build a package outside the UE editor?

I was not able to build a package directly from editor:

LogOutputDevice: Error: === Handled ensure: === 
LogOutputDevice: Error: Ensure condition failed: BuildTargetInfo [File:D:\build\++UE5\Sync\Engine\Source\Editor\TurnkeySupport\Private\TurnkeySupportModule.cpp] [Line: 447] 
LogOutputDevice: Error: CookOrPackage BuildTargetName='' IniPlatformName='Windows' Mode='1' 
BuildCookRunParams='-nop4 
-utf8output 
-nocompileeditor 
-skipbuildeditor -cook 
-project="S:/Unreal/Projects/Janek_new/Janek1.uproject" 
-unrealexe="S:\Unreal\UE_5.7\Engine\Binaries\Win64\UnrealEditor-Cmd.exe" 
-platform=Win64 
-installed 
-SkipCookingErrorSummary 
-JsonStdOut 'where BuildTargetInfo is null 
and architecture 'x64' is specified. 
One way to do this is to add c++ code to a project, 
but not build the project editor, then package. 
Returning without cook or package instead of asserting. 
LogOutputDevice: Error: Stack:

But it is possible to do it using cmd launched by umu wrapper:

cd $UE_PATH
./umu wineconsole cmd

This is the build command that you can change accorging to your needs:

set UE_PATH=Z:\Your\Path\To\UE_5.7
cd %UE_PATH%\Engine\Build\BatchFiles\RunUAT.bat BuildCookRun -nop4 -utf8output -project="%UE_PATH%\Projects\YourProject\YourProject.uproject" -unrealexe=%UE_PATH%\Engine\Binaries\Win64\UnrealEditor-Cmd.exe" -platform=Win64 -clientconfig=Development -serverconfig=Development -installed -nocompileeditor -skipbuildeditor -nobuild -cook -stage -package -pak -iostore -prereqs -archive -archivedirectory="%UE_PATH%\Projects\YourProject\Packaged\Win64"

This should produce packaged files into 'Projects/YourProject/Packaged/Win64`.

Be aware that UE 5.7 is unstable. Both Linux native and Windows version run on Proton are crashing very often so save your project often and try to tinker with DefaultEngine and DefaultEditor configuration.

Laravel 11: Vite in Twig (rcrowe/TwigBridge)

Adam Mateusz Brożyński — Mon, 01 Jul 2024 14:45:31 +0000

This registers vite tag to Twig that allows to dynamically link css and js (works for dev and prod):

{{ vite('resources/css/app.scss')|raw }}
{{ vite('resources/css/app.js')|raw }}

1. Create new Twig extension:

app/Twig/TwigExtension.php:

<?php
namespace App\Twig;

use Twig\Extension\AbstractExtension;
use Twig\TwigFunction;
use Twig\Markup;
use Illuminate\Foundation\Vite;

class TwigExtension extends AbstractExtension
{
    public function getFunctions(): array
    {
        return [
            new TwigFunction('vite', [$this, 'vite']),
        ];
    }

    public function vite(string $resource): string
    {
        return new Markup((new Vite)->__invoke($resource),'UTF-8');
    }
}

2. Generate config:

php artisan vendor:publish --provider="TwigBridge\ServiceProvider"

3. Add extension to config:

app/config/twigbridge.php:

        'enabled' => [
            ... 
            'App\Twig\TwigExtension',
        ],

Cronless queue:work in Laravel executed in background

Adam Mateusz Brożyński — Sun, 30 Jun 2024 23:28:56 +0000

There are some approaches how to execute queue:work but I found them useless. Here is a solution for most shared hostings that:

does not require additional route
does not require remotely visiting website
does not require shell access
does not require cron access
requires bash with flock on server (for single execution protection)
requires PHP exec function available
requires shell php command (php-cli installed on server)
runs in the background so makes no website slowdowns
can be set to execute not more than once between minimum time span of $runEverySec seconds

1. Let's create new Middleware:

$ php artisan make:middleware QueueWorkMiddleware

2. Use it as global middleware in `bootstrap/app.php`:

...
    ->withMiddleware(function (Middleware $middleware) {
        $middleware->append(App\Http\Middleware\QueueWorkMiddleware::class);
    })
...

3. Put contents to `App/Middleware/QueueWorkMiddleware.php`:

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;


class QueueWorkMiddleware
{

    // lock file that prevents too many executions
    public $lockFile = 'queue.lock';
    // log from queue command
    public $logFile = 'queue.log';
    // log from background exec command
    public $execLogFile = 'exec.log';
    // pid of executed command
    public $pidFile = 'queue.pid';
    // php command path
    public $phpExec = '/usr/bin/php';
    // queue:work command
    public $queueCmd = 'artisan queue:work --stop-when-empty';
    // minimum time in seconds between executions
    public $runEverySec = 10;

    /**
     * Handle an incoming request.
     *
     * @param  \Closure(\Illuminate\Http\Request): (\Symfony\Component\HttpFoundation\Response)  $next
     */
    public function handle(Request $request, Closure $next): Response
    {
        // get pid and lock file names
        $pidFile = base_path()."/".$this->pidFile;
        $lockFile = base_path()."/".$this->lockFile;

        if( 

            // if there is no lock file and
            !file_exists($lockFile) && 

            // there is no pid file (queue was never executed before)
            // or time between pidfile modification is more or equal $runEverySec
            (!file_exists($pidFile) || (time()-filemtime(base_path()."/{$this->pidFile}") >= $this->runEverySec))
          ) 
          { 
            // do the work
            $this->work(); 
          }

        return $next($request);
    }


    public function work() {     
        // file names
        $basePath = base_path();
        $lockFile = "{$basePath}/{$this->lockFile}";
        $logFile = "{$basePath}/{$this->logFile}";
        $execLogFile = "{$basePath}/{$this->execLogFile}";
        $pidFile = base_path()."/".$this->pidFile;

        // main queue command and lock file removal
        $cmd = "{ {$this->phpExec} {$this->queueCmd} > {$logFile} 2>&1; rm {$lockFile}; }";

        // go to base path and run command by flock (this guarantees single execution only!)
        $cmd = "cd {$basePath} && flock -n {$lockFile} --command '{$cmd}'";

        // execute command in background
        exec(sprintf("%s > {$execLogFile} 2>&1 & echo $! >> %s", $cmd, $pidFile));

        return true;
    }

}

nvidia-dkms-545 error in Ubuntu 24.04

Adam Mateusz Brożyński — Wed, 29 May 2024 12:18:41 +0000

nvidia-dkms-545 module won't build in Ubuntu 24.04 LTS with kernel 6.8. The only solution for now to have nvidia-driver-545 with CUDA is to remove linux-image-6.8.0-31-generic and use linux-image-6.5.0-35-generic instead.

Slack history archiver with UI

Adam Mateusz Brożyński — Thu, 07 Mar 2024 19:57:38 +0000

This project allows to download available message history from Slack server. History is limited in free accounts so this way you can keep private archive of messages by running script everyday via cron. To make it work you need only a website token and a cookie. There is also a UI based on Flask and Vue.

Ispconfig3 jailkit DokuWiki nginx directives

Adam Mateusz Brożyński — Mon, 04 Mar 2024 15:13:04 +0000

This directives can be saved in ispconfig3 admin panel and used for domains with DokuWiki.

    #Support for X-Accel-Redirect
    location ~ ^/data/ { internal ; }

    location ~ ^/lib.*\.(js|css|gif|png|ico|jpg|jpeg)$ {

    }

    location / { try_files $uri $uri/ @dokuwiki; }

    location @dokuwiki {

Ispconfig3 jailkit laravel api nginx directives

Adam Mateusz Brożyński — Mon, 04 Mar 2024 15:09:37 +0000

Ispconfig limits user webspace to public /web folder and /private folder. Since Laravel needs to use parent of public folder directory it is necessary to put all project files to /web including public folder. Here are working directives for nginx that allows to run laravel api project using ispconfig3 nginx directives that can be saved in admin panel and used for domain configuration. It redirects all public queries to /web/public folder.

location / {
   if (!uri) { rewrite ^ /public/index.php; }
   try_files /public/$uri /public/$uri/ @rewrite;
}

location @rewrite {
    rewrite ^/(.*)$ /public_html/index.php?$query_string;
}

    location = /public_html/favicon.ico { access_log off; log_not_found off; }
    location = /public_html/robots.txt  { access_log off; log_not_found off; }

    location ~ /\.(?!well-known).* {
        deny all;
    }

Wagtail menu with children

Adam Mateusz Brożyński — Mon, 26 Feb 2024 20:59:36 +0000

Unfortunately there's no examples of admin menu with submenu in Wagtail 6 docs, but here's Nigel van Keulen's solution from Wagtail's Slack #support channel:

# wagtail_hooks.py

from wagtail import hooks
from wagtail.admin.menu import Menu, SubmenuMenuItem, MenuItem, SubMenuItemComponent
from wagtail.images.wagtail_hooks import register_images_menu_item
from wagtail.documents.wagtail_hooks import register_documents_menu_item
from wagtail.admin.wagtail_hooks import register_collections_menu_item

# change app to your main app folder with settings/base.py
from app.settings.base import HIDDEN_SETTINGS_MENU_ITEMS, HIDDEN_MAIN_MENU_ITEMS


assets_menu = Menu(
    register_hook_name="register_assets_menu",
    construct_hook_name="construct_assets_menu",
)

@hooks.register("register_assets_menu")
def register_assets_menu():
    return register_images_menu_item()

@hooks.register("register_assets_menu")
def register_assets_menu_item():
    return register_documents_menu_item()

@hooks.register("register_assets_menu")
def register_assets_menu_item():
    return register_collections_menu_item()

@hooks.register("register_admin_menu_item")
def register_assets_menu_item():
    return SubmenuMenuItem(
        _("Assets"),
        name="assets",
        icon_name="folder-open-1",
        menu=assets_menu,
        order=300,
    )

@hooks.register("construct_settings_menu")
def hide_settings_items(request, menu_items):
    menu_items[:] = filter(lambda item: item.name not in HIDDEN_SETTINGS_MENU_ITEMS, menu_items)

@hooks.register("construct_main_menu")
def hide_main_items(request, menu_items):
    menu_items[:] = filter(lambda item: item.name not in HIDDEN_MAIN_MENU_ITEMS, menu_items)

# settings/base.py, adjust to needs

HIDDEN_SETTINGS_MENU_ITEMS = [
    "collections",
    "workflow-tasks",
    "workflows",
    "redirects",
    "menu",
    "groups",
    "users",
]
HIDDEN_MAIN_MENU_ITEMS = [
    "reports",
    "images",
    "documents",
    "wagtaildocs",

How to add edit link to wagtail-autocomplete items

Adam Mateusz Brożyński — Mon, 29 Jan 2024 18:54:15 +0000

Wagtail-autocomplete is a good solution for creating relations between pages. By default you can only search for a page and add or remove relation. Here is a solution to add edit icon that allows to edit related page in new tab.

In views.py we put page edit url to edit variable:

def render_page(page):
    if getattr(page, 'specific', None):
        # For support of non-Page models like Snippets.
        page = page.specific
    if callable(getattr(page, 'autocomplete_label', None)):
        title = page.autocomplete_label()
    else:
        title = page.title
    edit = reverse('wagtailadmin_pages:edit', args=[page.id])
    return dict(pk=page.pk, title=title, edit=edit)

In dist.js we look for this code (prettify first!):

return e.createElement("div", {
                                key: n.pk,
                                className: ee("selection")
                            }, e.createElement("span", {
                                className: ee("selection__label")
                            }, n.title), e.createElement("button", {
                                type: "button",
                                className: ee("selection__button"),
                                onClick: t.handleRemove.bind(t, n)
                            }, e.createElement(k, {
                                className: ee("selection__icon")
                            }), e.createElement("span", {
                                className: ee("sr-only")
                            }, "Remove")))
                        }))))

And we make it look like this:

return e.createElement("div", {
                            key: n.pk,
                            className: ee("selection")
                        }, e.createElement("span", {
                            className: ee("selection__label")
                        }, n.title),

                        e.createElement("div", {
                            className: ee("selection__controls")
                        },

                        // edit icon here
                        e.createElement("a", {
                            href: n.edit,
                            target: '__blank',
                            className: ee("edit__button")},
                            e.createElement("svg", {
                                className: ("icon icon-edit icon--item-action")},
                                e.createElement("use", { href: '#icon-edit'}),
                        )),

                        e.createElement("button", {
                            type: "button",
                            className: ee("selection__button"),
                            onClick: t.handleRemove.bind(t, n)
                        }, e.createElement(k, {
                            className: ee("selection__icon")
                        }), e.createElement("span", {
                            className: ee("sr-only")
                        }, "Remove"))))
                    }))))

Now we need to uninstall wagtail-autocomplete from pip and put our wagtailautocomplete folder with modified files directly to our app folder (where we have home, search etc. so it can be found by Wagtail).
