I don't know if this applies to embedded targets, but did you accidentally change the "Base environment for this run configuration" in Creator?
Go to Projects > Build & Run > Run Environment and check which value the combobox has; it should probably say "Build Environment", which is the default. Sometimes I accidentally mouse wheel over it when I'm scrolling down and it selects e.g. "Clean Environment", causing the application to fail to start because it's missing a bunch of environment variables. The error about the display in particular seems kinda familiar. From: Interest [mailto:interest-bounces+mitch.curtis=qt...@qt-project.org] On Behalf Of Abin Joseph Sent: Wednesday, 6 September 2017 8:27 AM To: interest@qt-project.org Subject: [Interest] Unable to do Valgrind Memory Analyzer on i.MX6Q target Hi, I am trying to do valgrind memory analysis with Qt Creator on iMX6Q board. I am able to run the application from Qt creator and also able to run application from terminal using command /opt/HelloWorld -platform wayland I have valgrind in my target board, and if I run valgrind -v /opt/HelloWorld -platform wayland, it gives me whole logs which are so difficult to trace out the exact errors. But still application launches. But if I click Analyze->Valgrind Memory Analyzer on Qt Creator, it gives me error and the application does not launch. If I do not give any run time arguments I get the error: Analyzing memory of /opt/HelloWorld QML debugging is enabled. Only use this in a safe environment. This application failed to start because it could not find or load the Qt platform plugin "xcb" in "". Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, wayland-egl, wayland. Reinstalling the application may fix this problem. Analyzing finished. ** Process killed by signal ** If I do not give any run time arguments -platform wayland, I get the error: Analyzing memory of /opt/HelloWorld QML debugging is enabled. Only use this in a safe environment. Failed to create display (No such file or directory) Analyzing finished. ** Unknown error ** Is there something I am missing to run valgrind memory analysis on iMx6Q board?
