[Solved] Transition Problem between different Qt libraries built by different MinGW versions
There has been QtSDK with Qt 4.8.0 on my system before. Then I’ve built Qt 4.8.4 libraries with the last MinGW version in order to add openssl support. Now when I add Qt 4.8.4 build configuration from Qt Creator’s projects settings, it crashes (forced to close). How should I do the transition between different Qt libraries built by different MinGW versions?
Qt SDK 4.8.0 libraries built by C:\QtSDK\mingw\bin
Qt 4.8.4 libraries built by the last MinGW version (C:\MinGW\bin)
The problem has been solved when I've used and installed Qt Creator 2.6.0. Thanks to developers for "Kits" module.
If you still experience problems: Please upgrade to the Qt Creator version found in the Qt 5 RC release (which is 2.6.0 plus quite some fixes, most of them to make it work better with Qt5). That version also includes a fix for an issue with different mingw versions causing crashes.
That version should become available as 2.6.1 once Qt 5 is out.
