multiple target patterns. Stop.

[MONTIN]

Hi all,

I am a beginer with Qt511 under windows XP with Qtcreator 2.8.1 and mingW48_32
I first try a console application "hello world", of course it works but when I add an external library without invoking it in the same code, I get this error : "Makefile.Debug:76: erreur : multiple target patterns. Stop."
What does that mean and how to fix it ?

Thanks

How are you adding this external library? What have you changed in your project?

Thanks for your reply.

I added it via the IDE (Right clic on the project and add a library, I tryed both the static and dynamic linking for windows only)

he project that works:

QT += core
QT -= gui
TARGET = Test_0
CONFIG += console
CONFIG -= app_bundle
TEMPLATE = app
SOURCES += main.cpp

and the second that does not works :

QT += core
QT -= gui
TARGET = Test_0
CONFIG += console
CONFIG -= app_bundle
TEMPLATE = app
SOURCES += main.cpp

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/C:/MCC/CWIN/ -lcbw32
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/C:/MCC/CWIN/ -lcbw32d

INCLUDEPATH += $$PWD/C:/MCC/CWIN
DEPENDPATH += $$PWD/C:/MCC/CWIN

win32:CONFIG(release, debug|release): PRE_TARGETDEPS += $$PWD/C:/MCC/CWIN/cbw32.lib
else:win32:CONFIG(debug, debug|release): PRE_TARGETDEPS += $$PWD/C:/MCC/CWIN/cbw32d.lib

Those 2 lines seem unnecessary:
@
win32:CONFIG: PRE_TARGETDEPS += $$PWD/C:/MCC/CWIN/cbw32.lib
else:win32:CONFIG: PRE_TARGETDEPS += $$PWD/C:/MCC/CWIN/cbw32d.lib
@

Thanks
Without these lines it does not work. I have reinstalled qt51 and now it works but only in release mode in debug mode i get this error

:-1: erreur : No rule to make target 'C:/qt/test/TestConsole0/../../../MCC/CWIN/cbw32d.lib', needed by 'debug\TestConsole0.exe'. Stop.

??

Can you help ?

I found a solution, maybe it is not the good one but it works.
When adding the library cbw32.lib under qtcreator I had cheked the option "add the d suffix for debug" BUT the file cdw32d.lib is not existing in my environnement that's why I had this error. Now it works.
Thanks sierdzio, with your reply, I did not feel alone with my problem ant it helps very much.
