Hello,

I can't run all the QThread applications. The problem is the same. Maybe the compiler need some configuration. I have the Qt 4.1.1 open source for windows XP. The problem is the following:

C:\Qt\4.1.1\MyThread>make
mingw32-make -f Makefile.Debug all
mingw32-make[1]: Entering directory `C:/Qt/4.1.1/MyThread'
