Problem with Qt Creator

[koahnig]

Interesting ! ? ! :-(

It may be

• the HW
• the compiler with your HW
• the installation
  Probably one can continue the list with more guesses.

Personally I would reinstall Qt SDK again. However, you have done that already at the beginning.
You could just reinstall MinGW4.7.2, but you may pick up some incompatibilities, if the compile models are not the same.

You could use your msvc2012 setup. However, this requires a complete build of Qt 5.0.1 because a pre-build with msvc2012 is not available. On an old machine this might take quite a bit of time. On more recent HW it takes typically a couple of hours to compile.
Compilation with msvc2012 had some issues. I am not sure if those are solved. You need to browse through this forum to find out.

You could download a previous version of MinGW (eg. 4.6.2) and check, if the compiler does work. However, you need to recompile Qt yourself.

You could revert to Qt4.8.4 and its prebuild for MinGW. The prebuild is based on MinGW 4.4 which is a pretty old version. This might help in case of an exotic issue based on combination new MinGW compilers with your old HW. However, you to check this forum where to download the MinGW compiler. It is no longer downloadable as an official MinGW distribution. However, that is managable. At least it would save yourself the compilation of complete Qt libs.

There might be more options. However, it is hard to know, which one will succeed.

Certainly new HW would help to circumvent all this.

It is all your choice.

The Athlon XP doesn't have the sse2 instruction set. Could this be the problem? Is Qt Creator being compiled with sse2 instructions included, which would then fail as an executable on Athlon XPs, Penium III and some Celerons?
