Hi Rainer,
have a look at the code.
CAppSetup* env = CAppSetup::getPlattformInstance();
env->/installMessageHandler/();
It crashes when accessing env. Therfore env must be a bad pointer. Let's have a
look at getPlattformInstance ()
CAppSetup* CAppSetup::getPlattformInstance()
{
if(nullptr == instance)
{
#ifdef Q_OS_MAC
instance = new CAppSetupMac();
#endif
#ifdef Q_OS_LINUX
instance = new CAppSetupLinux();
#endif
#ifdef Q_OS_WIN32
instance = new CAppSetupWin();
#endif
}
return instance;
}
Probably none of the defines is defined for MinGW/Cyqgwin. Or instance is not
nullptr as it is not pre-set. ->bug (I fix that).
Make sure getPlattformInstance() returns a good pointer.
