[SOLVED] My program crashes only when launched with QtCreator

billconan

hello,

my old machine got really slow. I then reinstalled new os (win8.1) on a new ssd.

after setting up Qt and everything, I noticed that my program will crash when launched with QtCreator. I didn't see this issue before. the crash happens before even calling into main().

I down graded my QtCreator to that of Qt5.2, the same problem still happens.

but if I directly run the built executable, everything is fine. only when I launch it with qtcreator, it crashes.

I enabled c++ exception in cdb, but it doesn't capture anything.

I don't know how to debug this. very weird problem.

the only changing factor seems to be the harddrive and the os. before I used win8, now it's win8.1

this doesn't happen with simple Qt examples. only my large project.

I kinda figure out the problem.
everything worked after I moved dlls from one folder to another. let me explain the details:

I selected "launch in console", and saw this error message:

exited with code -1073741515

this is an error of loading dlls.

usually, a qt project directory structure looks like this:

/root/qtproject
/root/build-qtproject_4_8_6-debug
/root/build-qtproject_4_8_6-debug/debug
/root/build-qtproject_4_8_6-debug/release

the executable is in /root/build-qtproject_4_8_6-debug/debug
but the default working directory is /root/build-qtproject_4_8_6-debug

I usually copy all the dlls inside /root/build-qtproject_4_8_6-debug, this worked for win7 and win8.

but somehow on win8.1, I have to copy dlls inside /root/build-qtproject_4_8_6-debug/debug, even in qt creator, the working dir is set to /root/build-qtproject_4_8_6-debug
