My app.pro has DEFINES += QT_MESSAGELOGCONTEXT
and log with qCDebug(embApp) << msg; or qDebug() << msg; in my source file.
How can i fix it?
You have to use the macros l4qError(..), l4qError(..) for logging? file, line, and function are only set if you use this macros.
If you log with:
logger()->debug() << "Debug output";
or
logger()->warn("Warning");
or ...
file, line, and function are not set.
Duplicate of #34
I think that find the reason why.
I compile the log4qt as third party, and then in order to capture the context in qDebug/qWarning as on, you will need in log4qt.pro add DEFINES += QT_MESSAGELOGCONTEXT, and in my project this is also needed.
I will verify it tomorrow, and give feedback here.
Fixed it!
If you compile the log4qt as third party, you need add DEFINES += QT_MESSAGELOGCONTEXT in log4qt.pro.
Also, you need add it in your pro which you want to capture context in release mode, if you doesn't see the context in logs, you will need to run qmake and rebuild your project.
I think that this should be added to build readme, if you want to build the log4qt as third party, using Qt internal QMessageLogContext and log4j.handleQtMessages=true.
