_ITERATOR_DEBUG_LEVEL error for libraries
-
I am having a Qt app with a few C++ libraries all built using Qmake & QtCreator on windows. I am using VisualStudio 2015 community edition which provides the C++ compiler to Qt on windows. By selecting debug option in bottom left corner, I generated debug libs out of all my library projects. But when I build my app in debug mode now, it results in following error.
LNK2038:mismatch detected for_ITERATOR_DEBUG_LEVELvalue0doesnt match value2in main.obj -
IIRC you can use
TARGET = $$qtLibraryTarget(MyLib) -
Hi,
AFAIK, it comes when you are mixing objects built for different type of builds. Did you clean everything before changing the build type ?
-
Yes I did. really strange. i just need the debug libs ONLY on windows so I am linking them on myapp.pro like this
LIBS += -L$$MyLib_build_location -lMyLib
Debug:win32: LIBS += -L$$MyLib_build_location -lMyLibD
INCLUDEPATH += $$MyLib_include_location/
DEPENDPATH += $$MyLib_include_location/
unix:PRE_TARGETDEPS += $$MyLib_build_location/MyLib.a
win32:PRE_TARGETDEPS += $$MyLib_build_location/MyLib.libIs above not correct ? Can you pls provide a sample ?

@SGaist Qt is not appending a D to the debug version of of lib. It names MyLib.lib even in debug version whereas I am expecting it to be MyLibD.lib. In pro file of my MyLib I have defined the following
TARGET = MyLib
Is it because of above line of code in MyLib.lib. Is there some way I can ensure that debug version of my lib gets a name with D appended to it ?

IIRC you can use
TARGET = $$qtLibraryTarget(MyLib) -
@SGaist Thanks a lot. That solves my problem.
