    Default Linking against different Libs

    I am using Qt Creator and want to link against different libs in debug mode.

    This is my .pro file:
    Qt Code: 
    1. # -------------------------------------------------
    2. # Project created by QtCreator 2009-02-06T01:28:15
    3. # -------------------------------------------------
    4. TARGET = uglyviewer
    5. TEMPLATE = app
    6. UI_DIR = tmp
    7. MOC_DIR = tmp
    8. INCLUDEPATH  += C:\\OgreSDK\\include
    9. SOURCES += src/uglyviewer.cpp \
    10.     src/main.cpp \
    11.     src/ogrewidget.cpp \
    12.     src/ogremanager.cpp \
    13.     src/inputmanager.cpp
    14. HEADERS += src/uglyviewer.h \
    15.     src/ogrewidget.h \
    16.     src/singleton.h \
    17.     src/ogremanager.h \
    18.     src/inputmanager.h
    19. FORMS += ui/uglyviewer.ui
    20. RESOURCES += res/resource.qrc
    21. RC_FILE = res/app.rc
    22. debug {
    23.     OBJECTS_DIR = tmp/debug/
    24.     RCC_DIR = tmp/debug/
    25.     LIBS = -L%OGRE_HOME%\bin\debug -lOIS_d -lOgreMain_d
    26. }
    27. release {
    28.     OBJECTS_DIR = tmp/release/
    29.     RCC_DIR = tmp/release/
    30.     LIBS = -L%OGRE_HOME%\bin\release -lOIS -lOgreMain
    31. }
    To copy to clipboard, switch view to plain text mode 

    The problem is that release overwrites debug because the Qt Creator always adds an debug_and_release to the CONFIG and therefore both debug and release are always definded.

    Use
    Qt Code: 
    1. CONFIG -= debug_and_release
    To copy to clipboard, switch view to plain text mode 
    to remove debug_and_release from the configuration (I dont know if this works with Creator, but thats the normal way to remove configuration entries)

    or define 2 targets. one for debug and one for release

    qmake Code: 
    1. CONFIG(debug, debug|release) {
    2.     OBJECTS_DIR = tmp/debug/
    3.     RCC_DIR = tmp/debug/
    4.     LIBS = -L%OGRE_HOME%\bin\debug -lOIS_d -lOgreMain_d
    5. } else {
    6.     OBJECTS_DIR = tmp/release/
    7.     RCC_DIR = tmp/release/
    8.     LIBS = -L%OGRE_HOME%\bin\release -lOIS -lOgreMain
    9. }

    Thank you guys! jpns snipped worked

    Edit: I wanted so save my executables to annother dir. the problem now ist that the Creator always start the binary inside the system folder even if I selected Debug as build mode:

    Qt Code: 
    1. CONFIG(debug, debug|release) {
    2.     OBJECTS_DIR = tmp/debug/
    3.     RCC_DIR = tmp/debug/
    4.     LIBS = -L%OGRE_HOME%\bin\debug -lOIS_d -lOgreMain_d
    5.     DESTDIR=bin/system_d
    6. } else {
    7.     OBJECTS_DIR = tmp/release/
    8.     RCC_DIR = tmp/release/
    9.     LIBS = -L%OGRE_HOME%\bin\release -lOIS -lOgreMain
    10.     DESTDIR=bin/system
    11. }
