Hello,

I'm trying to import okular from git into KDevelop with cmake. Building the project with Ninja an Llvm works fine, but when I try to debug the project, lldb stops automatically without showing the window. When I set a breakpoint in the first line of the main, I'm able to go through step by step for one line. At the line with "QApplication app(argc, argv);" the debugger stops. In the debugging window is the following Message:

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-martin'
qt.qpa.screen: QXcbConnection: Could not connect to display
Could not connect to any X display.
*** Normal beendet ***

While debugging the breakpoints in the symbol column are not visible. Also when the debugging ends, the breakpoints are not visible but still are present which I see in the breakpoints tab.

I already tryed to build the project with gcc (-DCMAKE_CXX_COMPILER=g++) and debugging with lldb (did not find the option to change to gdb), but it does not change anything.

With qtcreator I can debug the hole main and okular starts after getting to the app.exec() loop. But I cannot set breakpoints in an other file.

Best regards,

Martin
