Seer uses Qt's logging in a few places. This is for the purpose of debugging issues
|
|
for a released version.
|
|
|
|
Qt's logging is described in:
|
|
|
|
https://doc.qt.io/qt-5/qloggingcategory.html
|
|
|
|
Seer has these logging categories:
|
|
|
|
seer.seergdbwidget.debug # The object that communicates with the gdb process
|
|
seer.gdbmonitor.debug # The object that monitors output from the gdb process
|
|
^ ^ ^ ^ ^___^___________The logging channel. Can be debug, warning, critical, info.
|
|
| | |________|_________________The logging category. It should follow the Seer class name, in lowercase.
|
|
|__|____________________________Always the seer name.
|
|
|
|
Not all Seer classes have logging programmed. The above list will be updated as needed.
|
|
|
|
There are a few ways to enable logging. The easiest is by the environment variable.
|
|
Turn on logging like this:
|
|
|
|
% export QT_LOGGING_RULES="default.debug=true"
|
|
% export QT_LOGGING_RULES="default.debug=false;seer.gdbwidget.debug=true"
|
|
% export QT_LOGGING_RULES="default.debug=false;seer.gdbmonitor.debug=true"
|
|
% export QT_LOGGING_RULES="default.debug=true;seer.gdbwidget.debug=true"
|
|
|
|
To turn on simple logging of qDebug(), et al, set this:
|
|
|
|
% export QT_LOGGING_RULES="default.debug=true"
|
|
|
|
Then start seer. There should be lots of debug output.
|
|
|
|
|
|
|
|
If qDebug() output is missing filename and lineno information. Like:
|
|
|
|
[16:57:16][unknown:0][default] Some text...
|
|
|
|
Then build with debug turned on.
|
|
|
|
cmake -DCMAKE_BUILD_TYPE=Debug ..
|
|
