Running Windows Tools on Linux

This article will cover the process of running Hammer on Linux-based operating systems and address many common questions or issues that may arise.

Prerequisites

This process uses a program named Wine , which is a translation layer that converts calls for Windows into native Linux calls, without the need for emulation. Wine can be installed using your distro's appropriate package manager, typically under the package name wine, or from Wine's website.

Caution:

Since Wine 11, both the 32 and 64 bit packages of wine have been combined into one, so you only need to install the wine package for the tools to run properly. Installing the seperate outdated 32 and 64 bit packages is not recommended and will likely cause issues.

If using a Virtual Machine or emulator such as WinBoat, the tools should work as-is, apart from any configuration file changes.

Running Windows Tools

This section uses Hammer as an example, but applies also to HLMV and Faceposer. Just replace all instaces of hammer.exe with the appropriate executable.

First, run a Terminal window and navigate to <game>/bin/win64 using cd. Now, copy this command into the terminal:

wine hammer.exe -winecompat -game "./../../YOUR_MOD_HERE"

Tip:

If you are starting Hammer for the first time on your system, -game should not be necessary, as the default config file will usually generate a correct path. Once you run this option, Hammer should launch and provide you with the normal configuration prompt.

For HLMV/Faceposer, -game is required and the program will fail to launch or throw frequent errors if it is missing.

If you are running Hammer after previously using the program on Windows, you will have to edit your configurations to the correct filepaths. Make sure to point to the Windows executables, even for tools that have Linux-native versions, as Wine is not able to run Linux applications.

Creating a Shell script

For ease of use, you may find it useful to create a Shell (.sh) script that automatically runs Hammer under wine. Here is an example of a script for Portal 2: Community Edition named hammer.sh located in /bin/linux64/.:

echo "Launching Hammer under Wine" cd "./../win64" wine "./hammer.exe" -winecompat -game "./../../YOUR_MOD_HERE"

If placing this script somewhere other than /bin/linux64, then make sure to change cd "..." and -game to the appropriate path. When in doubt, use an absolute path.

When you create the file for the first time, you may need to give it permission to execute. This can be done by running this command:

sudo chmod +x "./hammer.sh"

Common Issues and Fixes

This section should cover most of the issues most users have when setting up Windows tools. If this guide does not solve your issue, as for help in your game's Discord server. Make sure to list what steps you have taken to attempt to solve the issue, and follow Dont Ask to Ask !

"Setup file 'gameinfo.txt' doesn't exist in subdirectory" when launching

Typically, this occurs when a path in your configuration file is incorrect, especially for Hammer if it has previously been run on Windows.

For Hammer, if you see the Select Config dialog when you start the program, edit the config to use the correct path.

For HLMV or if you only have one config for Hammer, first try making sure that the path specified in your -game option exists and that a gameinfo.txt file exsits. This should fix most cases of broken paths. If this does not fix your issue, navigate to <game>/hammer/cfg and either delete or rename gameconfig.txt. This will recreate your game configuration file next time you start Hammer, and will likely fix all issues with broken paths. Alternatively, you can manually edit the file to alter the paths to their correct location.

Note:

Wine prefixes all paths with a fake drive letter, Z: by default, to maintiain compatibility with Windows filesystems. Make sure to add this to the beginning of all your paths for them to work correctly.

My game looks washed out when ran from Hammer!

In some distros or Desktop Environments, when launching the game through the compilation can appear washed out or overbrightened when ran through Wine. This appears to be an issue with how some Desktop Environments, like Hyprland, interact with Wine applications, so the best way to remedy this issue is by running the game through Steam and manually running the map through the console.

"Portal 2 is not installed" (Portal 2: Community Edition)

This error can occur for a variety of reasons, but usually it is because Portal 2 cannot be found by Steam. Make sure that Portal 2 is in fact installed and visible in your Steam library, then try Verifying the game files of both Portal 2 and Portal 2: CE. Next, try restarting Steam to reload your library. If this does not fix your issue, try moving your Portal 2 install to the same drive as your Portal 2: Community Edition install. If all else fails, contact a programmer with your issue.
