QT5 (VisualStudio2012 addin) won't link
-
Hi,
i just startert working with Qt5 for some university worksheets, and im even stuck before i really started.
I use VisualStudio2012 Ultimate (latest version update1) with the lates version of the QT addin.
My Code Compiles fine, but uppon linking i get tons of errors. The first one:
@
error LNK2038: Konflikt ermittelt für "_MSC_VER": Der Wert "1600" stimmt nicht mit dem Wert "1700" in bmi.obj überein.@
(Translated: Conflict detected for....: The Value"1600" is not the same as the Value "1700" in bmi.obj ) (i'm writing a bmi calc so bmi.hpp and bmi.cpp contain my main class)After that i get
@error LNK2019: Verweis auf nicht aufgelöstes externes Symbol ""__declspec(dllimport) public: __thiscall QWidget::QWidget(class QWidget *,class QFlags<enum Qt::WindowType>)" (_imp??0QWidget@@QAE@PAV0@V?$QFlags@W4WindowType@Qt@@@@@Z)" in Funktion ""public: __thiscall BMI::BMI(void)" (??0BMI@@QAE@XZ)".
error LNK2019: Verweis auf nicht aufgelöstes externes Symbol ""__declspec(dllimport) public: virtual __thiscall QWidget::~QWidget(void)" (_imp??1QWidget@@UAE@XZ)" in Funktion "__unwindfunclet$??0BMI@@QAE@XZ$0".
@(Both are the same error message, which translates to: "Reference to unresolved extern symbol", there are way more of those errors, pasting them all would be quite pointless i think)
and after that lots and lots of:
@error LNK2001: Nicht aufgelöstes externes Symbol ""protected: virtual void __thiscall QWidget::actionEvent(class QActionEvent *)" (?actionEvent@QWidget@@MAEXPAVQActionEvent@@@Z)".
error LNK2001: Nicht aufgelöstes externes Symbol ""protected: virtual void __thiscall QAbstractSlider::changeEvent(class QEvent *)" (?changeEvent@QAbstractSlider@@MAEXPAVQEvent@@@Z)".
@which translates to: Unresolved extern symbol
if you need the code just say it, but i think i did somethign wrong on setting everything up and not with the code itself.

Well the variable _MSC_VER holds the compilers version number. 1600 is for vs2010 and 1700 is for vs2012.
"MSDN _MSC_VER definition":http://msdn.microsoft.com/en-us/library/b0084kay.aspx
"This might help some...":http://stackoverflow.com/questions/4061929/help-with-linker-error-lnk2038
Also, the install for the Qt libraries is compiled for 2010 not 2012.

so basically there is an addin for vs2012 but vs2012 itself is not supported -.-
i guess the easiest solution would be installing vs2010? is the express version enough as it should bring everything compilerrelated with it?
e: nope, and i have no idea how i would do that. i think i remember seeing a tutorial for that yesterday (even though i can't find it now) but i think there where quite some needed tools and i really don't wanna mess up my whole system with compilers and stuff for one use...

qt creator does not want my vs2012 compiler as well.. i tried mingw, didn't work out as well. (no compiler found, even if the correct kit is selected).
guess i would have to use 4.8 with minggw for that. but i try compiling it, i guess i migth be using qt even after those university exercises^^ always wanted to get into gui programming and not only cmd programms...
-
so, i build qt5 (i think succesfully as i had no errors)
but again, another linker error that says:"Qt5Guid5.lib cannot ne opened". and well in the path where it trys to open this file it doesn't exist. There is one Qt5Gui.lib and a Qt5Guid.lib bot no Qt5Guid5.lib...
the path is: C:\qt-source\qt5\qtbase\lib\Qt5Guid5.lib and the q path is set to the qtbase folder.
e: found the bug report... i guess i can just change that in the linker settings.
e2: yep, working as it should :)
