Problem with qt5 and cryptopp

Hi.
Recently, I downloaded QT 5 from here http://releases.qt-project.org/digia...st_successful/ (mingw version).
I was trying to compile and link the cryptopp library but I have lot of errors that I didn't have when I was using mingw with gcc in version 4.4 (qt 4)

Code:

---

cryptlib.cpp:-1: error:undefined reference to `_Unwind_Resume'

---

I tried to build with gcc, g++ but always the same error.
The version of gcc in mingw that I am using is 4.6.1, this is only version that is working with qt5 under windows, mingw with gcc 4.7 give me errors like:

Code:

---

:-1: error:[ui_about.h] Error -1073741515
 
 
Makefile.Debug:2333: recipe for target 'ui_about.h' failed

---

Any idea what could help?
