Integration UI Error

[dadal00]

Issue summary

After compiling the Integration UI with make, I am unable to properly run the executable. I get the below errors.
make

qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Aborted

In addition, when I was running cmake I got the below warnings even though I have installed both python and CapnProto. I was wondering if this was affecting the compilation.

sudo cmake . -DBUILD_UI=ON -UPYLIB_DIRECTORY

-- Could NOT find Python (missing: Development.Module) (found suitable version "3.10.12", minimum required is "3")
CMake Warning at CMakeLists.txt:306 (message):
  Could not find CapnProto, disabling search save/load

System information

• Ubuntu 22.04
• Python 3.10.12
• Gym Retro 0.9.2

You are using WSL2 right?
Just as a note you don't have to use sudo to run cmake

Just so I repro your issue. You did a fresh install of Ubuntu 22.04 on WSL 2, then ran these commands for integration tool?

sudo apt-get install python3 python3-pip git zlib1g-dev libopenmpi-dev ffmpeg
sudo apt-get install capnproto libcapnp-dev libqt5opengl5-dev qtbase5-dev
#Get the lastest retro source code
git clone https://github.com/Farama-Foundation/stable-retro.git
cd retro
cmake . -DBUILD_UI=ON -UPYLIB_DIRECTORY
make -j$(grep -c ^processor /proc/cpuinfo)

I am using WSL2 and without the sudo I get the following output for cmake. Otherwise I ran the same commands to build the integration UI. The only difference would be that I cd into stable-retro instead of retro.

I also tried using Ubuntu 20.04 on WSL2 and I was able to get a different cmake output without using sudo.

However, I still get the same error when I compile the integration UI using the above steps.

qt.qpa.xcb: could not connect to display 
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Okay, I was able to get it to work. I had to install VcXsrv, then run XLaunch. These additions are mainly because I am using Ubuntu on WSL2 so I would need to do some configurations to connect the X server.

Within the application window of XLaunch keep clicking next until you get here and make sure the "Disable access control" is checked".

Then, open Ubuntu and put these commands in.
