When trying to switch to gcc 4.6.2 in qt (setting it in a toolchain)

When trying to switch to gcc 4.6.2 in qt (setting it in a toolchain) I’m getting the following error: 

c:\ndk_buildrepos\qt-desktop\src\winmain\qtmain_win.cpp:93: error: undefined reference to `_Unwind_Resume'

Any idea how to fix it?

//.pro
QMAKE_CXXFLAGS += -std=c++0x

SOURCES += \
    main.cpp

    1. I download and installed a Qt library alone (i didn’t download the whole SDK)
    2. I Wrote a simple Hello Qt window..
    3. I link it with my Dev-Cpp (since Dev-Cpp is using MinGW as well) mine version actually is 3.4.x not 4.4.x…
    4. I compile it the Qt way using qmake .. etc..
    5. I got an error you have experienced as well..

    … “_Unwind_Resume …” …

    My Solution (simple, very simple)

    1. Run the Qt X.X.X. (Build Debug Libraries) or..
    2. Run the qtvars.bat (depending on the version of Qt you are using) mine is 4.8.0..
    3. 1 and 2 are the same thing..

    I did a hit of make again.. it runs..:)

    p.s. it solves my problem.:) I hope it can solve yours too.
