QtCreator use gdb as debugger is quite slow
-
System: Linux 64bit
Qtcreator version:
gdb version: 8.2_1
I found it is very slow if I use Qtcreator to do debugging, even just step to next line sometimes may cost 40 - 50 seconds. it has bothered me for almost 2 years, but still no solution.
if I use gdb directly, it can be very fast, less than 1 second.
this is my qtcreator debugger configuration:
and here's the debugger log info for a slow 'step into next line' operation:

I found it is very slow if I use Qtcreator to do debugging, even just step to next line sometimes may cost 40 - 50 seconds. it has bothered me for almost 2 years, but still no solution.

@fanyha
Are you showing anything in debugger Watch pane? Updating that after every step can be slow... -
System: Linux 64bit
Qtcreator version:
gdb version: 8.2_1
I found it is very slow if I use Qtcreator to do debugging, even just step to next line sometimes may cost 40 - 50 seconds. it has bothered me for almost 2 years, but still no solution.
if I use gdb directly, it can be very fast, less than 1 second.
this is my qtcreator debugger configuration:
and here's the debugger log info for a slow 'step into next line' operation:

new update:
I've found an important clue: if I start my program with 'env LD_PRELOAD='/some/path/qt/5.15.6_g/lib/libQt5Core.so /some/path/qt/5.15.6_g/lib/libQt5Gui.so /some/path/qt/5.15.6_g/lib/libQt5Widgets.so' the debugger can be very quick.
note /some/path/qt/5.15.6_g qt binaries have debug info, but my program's own used qt binaries don't.do you know why this happen?

@fanyha : It probably tries to use some Qt related debug info and doesn't find it in your build. There are more options you could try to switch off: GDB tab: "Use dynamic object type for display", and "Locals & Expressions" tab: "Show QObject names if available".
