QtCreator and TBB under Windows

Question

I have compiled TBB from source using Mingw following the comment #5 in this post: http://software.intel.com/en-us/forums/topic/291331. That went ok.

When I try to use the new TBB library in a QtCreator project, I end with this errors (ignore the warning messages): http://postimage.org/image/yrrecugix/

Here's the sample code I tried (I omit the non-tbb code):

#include "tbb/task_scheduler_init.h"

int main()
{
  tbb::task_scheduler_init init;
  /// more things.
}

And here's the .pro file:

TEMPLATE = app
CONFIG += console
CONFIG -= qt

SOURCES += main.cpp

#QMAKE_CXXFLAGS += -fopenmp
#QMAKE_LFLAGS += -fopenmp
INCLUDEPATH += "E:\TRABAJO\LIBRERIAS\tbb-4.1_src\include"
LIBS += -L"E:\TRABAJO\LIBRERIAS\tbb-4.1_src\build\windows_intel64_gcc_mingw4.5.4_debug\" \
        -ltbb_debug

Any idea?.

Thanks!.

When built with MinGW on Windows, TBB binaries are tbb.dll and tbb_debug.dll. The option -ltbb_debug in your configuration files probably causes the linker to look for libtbb_debug.<something>. It can't find such a binary and reports about unresolved symbols.
