QDriverStation Crashes After compilation about qdriverstation HOT 16 CLOSED

Well, I did not stumble with this error before. Some Google searches indicate that this error could be related to GCC (e.g. using an older version that does not fully support C++11). Could you try to follow the commands outlined in the Travis build file?

Anyways, I will install Ubuntu 14.04 on a VirtualBox and see what happens. If I find a solution, I will post it here.

Thanks for the report!

Update It seems that your error comes from the code that gets CPU usage under Linux. We use regex to do that, which only works with C++ 11 or greater. Updating your GCC to a later version (e.g what the Travis CI file does) should fix your issue.

Let me know if the above solution works for you!

Thank you for answering,
I have tried both with gcc and g++ version 4.8 and with them version 4.9 that supports c++11 but didn't manage to run the program.

@GreenBlitz4590Programmers @DanielEliad I will try to replace the standard regex functionality with Qt's built-in regex functionality. Hopefully this will fix this issue.

Update I re-wrote the code that obtained CPU usage under GNU/Linux using Qt functions. The application should compile and run fine, regardless of GCC version or C++11 support.

@DanielEliad @GreenBlitz4590Programmers Can you try the latest commit to see if this issue was solved?

Thank you so much for helping, i'm trying it out right now. actually Daniel and I are the same person. This account is my FRC tean's github account.

Unfortunately, it didn't work. However, now I am getting a different error message,

Well at least we got our first issue solved 👍

For the second error to be fixed, you must install qml-module-qt-labs-settings. If you are using Ubuntu 14.04 or 14.10, you may need to download and install this package manually, since it is available for Ubuntu 15.04 or greater.

I have been trying to find a way to install this package manually, I found a .deb file and installed it but now I am getting this message saying the version does not suffice:

I have installed both qml-module-qt-labs-settings version: 5.3.0 and 5.4.2
I have tried installing version 5.5.1 but htis outputs the message:

Do you have any ideas?

Thanks in advance 👍

The only thing that I can think of is adding a PPA to your system and upgrading Qt with it, you can do this with the following commands:

sudo add-apt-repository ppa:beineri/opt-qt57-trusty # Add repository
sudo apt-get update                                 # Update package list
sudo apt-get install qt57*                          # Install every Qt 5.7 component
sudo sh /opt/qt57/bin/qt57-env.sh                   # Setup correct environment (according to repo)

Note: I have not tested these commands, I am just following the repository instructions.

It worked!

Thank you so much for your help 😄

@DanielEliad Glad to hear it! Thanks for the report!
@GreenBlitz4590Programmers Did you manage to fix your issues? Maybe we still can help you out.

We are the same person actually, one account is just my FRC team's account and the other is my private account.

I am having one issue which may be present in the original driver station for windows. I am using 2 Logitech Extreme joysticks and one XBOX controller. When I connect all three the driver station(both in windows and linux) detects two joysticks as the same one, so when I move either joystick the axis values change in a single joystick element. There is another joystick element, but no actual joystick changes it's values.

Did you hear about this issue before?

from qdriverstation.

Also now I appear to not have connection through QDriverStation but I do have a connection to the robot through wine.

Maybe these warnings have to do with it:

00:00.6 WARNING QSslSocket: cannot resolve SSLv2_client_method
00:00.6 WARNING QSslSocket: cannot resolve SSLv2_server_method

from qdriverstation.

These warnings are about the updater, nothing to worry about. I have received other issues regarding the communications...I am uploading the fixed builds right now :)

Regarding the joysticks, I will open a new issue about them (so that we keep the issues organized) and mention you there.
