Qt + RaspberryPi Compile issues
My friend is working on a Pi project and he found some issues on cross compiling Qt5 with raspberry pi. The issues are added below. Any help is really appreciated.
1). After referring this guide http://wiki.qt.io/Raspberrypi_beginners_guide, I was able to deploy my project on raspberry but i am not able to see GUI on my PC. Then i connect raspberry pi with TV through HDMI and there i am able to see the GUI. So does that mean GUI will only display on separate connected TV or i have done something wrong step?
2). The "websocket" project builds successfully on DESKTOP KIT. But when i select my RASPBERRY KIT, it shows error like 'no websocket module'.
3). Using 'wiringPi' library with Qt deploys successfully to Raspberrypi, but it shows run time error like: "wiringPi must be root", So is there any way to run my qt project with root privilege ?
Thanks in advance
1.) You haven´t done something wrong. The deployed application is running on your pi and therfore not displayed on your pc.
2.) It seems you didn´t configure / compile the websocket modul.
3.) You can change the deployment configuration of your projects to run your application with sudo. The default pi user is in root group.
Thanks for that. Let me check with my friend, I hope this will solve his problem.
Hi, I suggest you to use pigpio instead of wiringpi. You can run an application on raspberry with ssh -X and sudo.
