Basic apps builds crash as soon as I add a new class...
I installed Qt 5.5.1 (Creator 3.6.0) with all the default options.
The compilator is MinGW 4.9.2 32 bit.
I have Windows 7 64 bits, and an Intel i5 processor.
I tried to open an old Qt project of mine, the compilation process is fine, but the build .exe does nothing, there is no error message and I can't even kill the process.
While investigating I realised it is the same with almost any Qt project, even the built-in exemples ! Only the basic ones with only a single main.cpp (and eventualy resources) work.
If I just add a new class to these working projects (just basic cpp and h files, no function or attributes at all beside the constructor), again the compilation is fine but the build does not run !
I tried reinstalling the whole thing, no effect.
I really have no clue what is happening, if anyone have an idea...
Nevermind, it was only Avast Antivirus blocking the builds without any notification...
