Qt Project How to ?

Could someone help me write a .pro file that by default compiles in both release and debug mode. In release mode. I don't want the debug message from qDebug() to get printed

I tried some thing like this. But to no avail

Qt Code:

Switch view

TEMPLATE = app
TARGET   = Driver
 
DESTDIR = ../Bin
 
CONFIG += qt \
          plugin \
          warn_on \
          debug_and_release  \
          build_all
 
UI_DIR = Build/Ui
MOC_DIR = Build/Moc
OBJECTS_DIR = Build/Obj
 
CONFIG( debug, debug|release ) {
    CONFIG += console      #show console in Windows platform
    CONFIG -= app_bundle   #console in MAC also
    unix: TARGET = $$join( TARGET,,,_debug)
    else: TARGET = $$join( TARGET,,d)
}
 
release {
    DEFINES += QT_NO_DEBUG_OUTPUT
}
INCLUDEPATH = ../Common/Include \
              ../Plugins/Include
 
DEPENDPATH  += ../Common/Include \
              ../Plugins/Include
 
#HEADERS +=
 
SOURCES += Src/main.cpp

TEMPLATE = app
TARGET   = Driver

DESTDIR = ../Bin

CONFIG += qt \
          plugin \
          warn_on \
          debug_and_release  \
          build_all

UI_DIR = Build/Ui
MOC_DIR = Build/Moc
OBJECTS_DIR = Build/Obj

CONFIG( debug, debug|release ) {
    CONFIG += console      #show console in Windows platform
    CONFIG -= app_bundle   #console in MAC also
    unix: TARGET = $$join( TARGET,,,_debug)
    else: TARGET = $$join( TARGET,,d)
}

release {
    DEFINES += QT_NO_DEBUG_OUTPUT
}
INCLUDEPATH = ../Common/Include \
              ../Plugins/Include

DEPENDPATH  += ../Common/Include \
              ../Plugins/Include

#HEADERS +=

SOURCES += Src/main.cpp

Try this:

Qt Code:

Switch view

CONFIG += debug_and_release
 
CONFIG( release, debug|release ) {
   DEFINES += RELEASE
}
 
CONFIG( debug, debug|release ) {
   DEFINES += DEBUG
}

CONFIG += debug_and_release

CONFIG( release, debug|release ) {
   DEFINES += RELEASE
}

CONFIG( debug, debug|release ) {
   DEFINES += DEBUG
}

Sorry I did not get you ?

If you run qmake on that .pro file, you'll two Makefiles, which look like this:

Makefile.Debug:

...
DEFINES = -DDEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED
...

Makefile.Release:

...
DEFINES = -DRELEASE -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED
...

Now you can replace DEFINES += xxx with whatever you want.

with CONFIG += debug_and_release

In Qt 4.1.4 running qmake && make; compiles the project in debug mode
where as in Qt 4.3.0, the Makefile generated runs the Makefile.Release by default, can I force it use the Makefile.debug
