My app launches from inside Qt Creator no problem, but when I go into the debug folder, I
find the .exe file and I try to launch it, it complains that there is a missing DLL called mingwm10.dll.
I don’t know how to fix this problem I tried the release as my build target, same thing happened.
Unless you compiled Qt statically and link to it statically, you will need to copy the Qt DLLs with your app when you go to deploy it to another computer, just copy the mingwm10.dll with them (it’s in at least two places in my Qt install:
<install path>\Qt\2010.02.1\mingw\binand<install path>\Qt\2010.02.1\qt\bin).For just running on your own machine, I would suggest you add the
<install path>\Qt\2010.02.1\qt\binpath to your “Path” environment variable. This should allow your apps to run properly outside the IDE without having to copy the dll around for every project until you go to deploy it elsewhere.
