Overgrowth Linux

From Wolfire Games Wiki
Jump to: navigation, search

The Linux version of Overgrowth has different dependencies which need to be fulfilled, otherwise the game won't run. Those dependencies can vary from distribution to distribution.


We currently don't ship an installer anymore, but we intend to do this in the future.

The Linux installer is a Bash script which loads a graphical installer. The shebang points to /bin/sh, but it will not work with every shell.

# readlink -f /bin/sh

If the installer won't load and /bin/sh doesn't point to bash try to force using bash.

# bash overgrowth-xxx-linux.sh

root rights are not necessarily required to install Overgrowth. If you only have a single user on your system (that wants to play Overgrowth) it is not a bad idea to install it to your home directory, because then you do not have to start SUMLauncher as root user.



This also includes Ubuntu, Mint etc.


# apt-get install libfreeimage3
# apt-get install libalut0
# apt-get install libsdl-net1.2

64-bit systems

The following is no longer necessary as we build and deliver a 64 bit binary package, but is still necessary if you wish to run the 32 bit version.

Overgrowth tries to access the 32-bit (i386) version of many libraries whose 64-bit version (amd64) might already be installed in your system. In order to install the 32-bit version of these libraries, append :i386 at the end of the package name when using apt-get. For example, when running Overgrowth Alpha 208 on a 64-bit Ubuntu 14.04, the following 32-bit libraries must be installed, despite its 64-bit versions already being installed:

sudo apt-get install libgconf2-4:i386 libnss3:i386 libgtk2.0-0:i386 libglu1-mesa:i386 libxft2:i386



Overgrowth needs different libraries in order to work. This list might not be complete.

# emerge -av gnome-base/gconf
# emerge -av media-libs/freeimage
# emerge -av media-libs/freealut
# emerge -av media-libs/libpng:1.2
# emerge -av media-libs/libsdl-net:1.2


If your user is not already in this groups you have to add him. Otherwise the game may not start and it is even possible that X will completely crash.

# gpasswd -a your_user audio
# gpasswd -a your_user video


SUMLauncher does not work with dev-java/sun-jdk, you will need dev-java/icedtea-bin to use it.

# emerge -av dev-java/icedtea-bin
# eselect java-vm list
Available Java Virtual Machines:
  [1]   icedtea-bin-6 
  [2]   sun-jre-bin-1.6  system-vm
# eselect java-vm user set 1


You can install the package overgrowth from the AUR.


If you install the AUR package all required libraries should be pulled in automatically. If you install Overgrowth manually, using SUMLauncher or using Steam you will need to acquire the dependencies manually. The following should provide a good starting point:

# pacman -S --needed freeimage freealut sdl sdl2_net


You can install the package sumlauncher from the AUR.

Problems and solutions

Overgrowth currently has many severe bugs and issues on Linux. Luckily, there are fixes or workarounds for most of them. The below specifically assumes a199, so please upgrade before trying the suggestions here.

Errors about GLSL appear, mentioning GLSL versions.

This is another one that happens with Intel graphics on Linux. Add #version 130 to the tops of all files that end with .vert or .frag, but not any of the files that end with .glsl, in the Overgrowth/Data/GLSL directory. If you install mods that provide new shaders you may need to fix them as well.

You can use BASH code:

# cd to your Overgrowth/Data/GLSL
cd /usr/local/games/Overgrowth/Data/GLSL
# adds #version 130 to files
for f in $(ls *.vert *.frag); do echo -e "#version 130\n$(cat $f)" > $f; done

Textures are missing. Loading screen shows a white box and the game appears in black and white

Overgrowth requires S3TC texture support, which is not enabled by default in open source graphics drivers. If you have this issue, you need to set up S3TC texture support. You can probably find out how by googling

S3TC <your distro here>

Also, you may need to start with "LC_ALL=en_US" parameter e.g.:

LC_ALL=en_US ./Overgrowth.bin.x86_64 

Could not find "Data" folder

Unlike Windows systems, Unix-based systems are mostly case-sensitive in its directory paths. This reflects when, after starting Overgrowth, the system tries to find a "Data" folder, when the folder that is provided is actually called "data", without the capital D. Changing the lowercase D to uppercase should fix this issue.
