SIGSEGV fault when compiling with custom MinGW distro (but OK with Qt's MinGW)



  • Hello, I am developing an application on Qt using Qt Creator, so far so good,
    but my partner asked me if i could use another distro of MinGW from http://nuwen.net/mingw.html, that He has been using for a while and He is happy with it so I decided to give it a try.

    I was able to add the new toolchain to Qt creator without major problems, and the building worked OK, but when running the application sent a SIGSEGV fault, this happens when launching the app, I a run the release version, crashes without message.

    Thank you and I hope someone can help me with this.



  • You might run into binary compatibility issues between the libraries (built using GCC 4.4) and your application (built using GCC 4.7 C++11).

    "Rebuild the libraries":http://qt-project.org/wiki/Get_The_Source using your new toolchain.



  • Thank you very much, that seems to be the problem
