Linux / FreeBSD

Installing

Ubuntu 15.10 or higher

You can install tgui by adding the PPA to your system and install the "libtgui-dev" package:

sudo add-apt-repository ppa:texus/tgui-0.7
sudo apt-get update
sudo apt-get install libtgui-dev

Arch Linux

You can download, build and install the latest tgui version with the "tgui-git" packet from the AUR. There are multiple ways to do this, here is one:

yaourt -S tgui-git

Other distros / FreeBSD

Download the source code from the download page.

You will need to use CMake in order to build TGUI. How you do this depends on your distro, but it will be similar to “sudo apt-get install cmake” (Ubuntu) or “sudo pacman -S cmake” (ArchLinux).

Also make sure that you already have sfml on your computer. It would be even better to make sure you have sfml working before trying to use TGUI. If something goes wrong afterwards, you can be sure that the problem does not lie with sfml.

Type the following in the terminal in order to install tgui. Of course you will have to be inside the downloaded tgui directory. You can change the 2 in -j2 to a higher number if you have more cores.

cmake .
make -j2
sudo make install

Using TGUI (Terminal)

The two things to add is linking to tgui and tell the compiler that it uses c++11.

g++ -std=c++11 main.cpp -ltgui -lsfml-graphics -lsfml-window -lsfml-system -o program

Using TGUI (CodeBlocks)

Open the “Project build options” and choose whether you want to change debug or release target settings. Or you can just click on the name of your project (here TGUI_Test) and set them for both.

CodeBlocks Project Build Options

Add ‘-ltgui’ to the “Linker settings” under “Other linker options”. The order should be as follows: first tgui, then the libraries from sfml. (you might also need to add -lGL at the end of the list)

CodeBlocks Linker Settings

You must also enable c++11.

CodeBlocks Compiler Flags

You should now be able to use TGUI.

Possible error

It is possible to get the following error when running your program:
“/pathname/of/program: error while loading shared libraries: libtgui.so: cannot open shared object file: no such file or directory”

If you get this then you did install tgui correctly, but it is not in the shared library cache.
All you have to do is open the terminal, type “sudo ldconfig”, hit enter and type your password.

If that doesn’t solve it then make sure the library was installed to a place where your distro searches for it.
The easiest solution is probably to add the line “/usr/local/lib/” (without the quotes) at the end of /etc/ld.so.conf and then run “sudo ldconfig” again.
