Locals and Expressions window is blank

BasicPoke

Hello, my Locals and Expressions window has stopped working and is blank. I have read that I should download gdb but I can't find that. What should I do? Would downloading the latest Qt help?

Here is my pro file:
@QT += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = GaugeMon
TEMPLATE = app

SOURCES += main.cpp
GaugeMon.cpp

HEADERS +=
../DAQ_C/cbw.h
GaugeMon.h

FORMS +=
GaugeMon.ui

OTHER_FILES +=

#---Following added when DAQ library was added---
#win32:CONFIG(release, debug|release): LIBS += -L$$PWD/../DAQ_C/ -lcbw32
#else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/../DAQ_C/ -lcbw32d
LIBS += -L$$PWD/../../DAQ_C/ -lcbw32

INCLUDEPATH += $$PWD/../../DAQ_C
DEPENDPATH += $$PWD/../../DAQ_C

The only thing that looks odd in my debug log is this:
@>&"Python Exception <type 'exceptions.UnicodeEncodeError'> 'ascii' codec can't encode character u'\xff' in position 867: ordinal not in range(128): \n"

&"Error occurred in Python command: 'ascii' codec can't encode character u'\xff' in position 867: ordinal not in range(128)\n"
3473^error,msg="Error occurred in Python command: 'ascii' codec can't encode character u'\\xff' in position 867: ordinal not in range(128)"
dDUMPER FAILED: 3473^error,data={msg="Error occurred in Python command: 'ascii' codec can't encode character u'\\xff' in position 867: ordinal not in range(128)"}

Any ideas? Thanks.

It started working again today for no apparent reason.

Ok, my Locals and Expressions window is sometimes blank, and occasionally works. Really annoying. Any ideas?
Thanks

Hi,

Got any non-ascii char in your code/data ?

BasicPoke

I don't believe there are any odd characters. Don't even have any C strings. Now I am losing debug info exactly when I need it, very frustrating. I have a breakpoint in a function, I stop there, step a few times (Locals and Expressions is working correctly), then add another breakpoint, click continue, then it stops at the new breakpoint. When I start stepping, the Locals and Expressions window all goes gray and values are no longer updated. The values are also wrong when I hover over a variable.

With the L&E window closed, then values when I hover are grayed out and incorrect.

I have restarted Qt Creator, powered down & rebooted. Any ideas?
Thanks
Ron

What OS and Qt Creator versions are you running ?

BasicPoke

Windows 7 64-bit, and I believe that was Qt Creator 3.1.0 and Qt 5.2.1. I installed Qt Creator "3.2.1 (opensource)" and the problem has gone away for now. I may be back later. Thanks for your help.
