Debugger won't break at breakpoints in qt creator



  • I have imported a project to Qt Creator (latest gedit from git) and I have now managed to make it run, but I'm still not able to debug it since it won't break at my breakpoints. The gdb output shows this:
    [QUOTE]&"warning: GDB: Failed to set controlling terminal: Inappropriate ioctl for device\n"
    no loadable sections found in added symbol-file system-supplied DSO at 0x7ffff7ffa000[/QUOTE]

    The second line is shown when debugging from the terminal too, but not the first one. Breaking works well from the terminal (but I prefer putting my breakpoints graphically).

    Did you do a debug build?

    The first line is due to GDB not being happy about being embedded into a UI... I have seen this with other IDEs, too. That one can safely be ignored.

    Yes. I configured the project with "CFLAGS='-g -O0' ./configure". Then Qt Creator builds with make and runs it. That should do it, right?



  • Anyone? This really bugs me out



  • What kind of project are you building? Does it consist of shared libraries and such?



  • Got a similar error in gdb:

    @warning: no loadable sections found in added symbol-file system-supplied DSO at 0x7ffff7ffa000@

    I was able to run gdb without problems, but since I've installed the Qt 5 libraries from the installer (as opposed to previously building from Git), this error suddenly showed up.

    Any solutions?
