build qt program in release version run carsh

[leeguevara]

I write a Qt program and build a release version "myProgram.exe" to run on other PC. The release version can run on my pc, but can't run on other pc. Other pc didn't install Qt enviroment, but I copy the QtCore4.dll and QtGui4.dll to the same directory with "myProgram.exe". When I run "myProgram.exe", the program will crash, the error information is "APPCRASH, ..., error module: QtCore4.dll, ..., error code: c0000005".
I write and build "myProgram.exe" using vs2010
Thanks a lot.

you should use an installer - maybe those dlls are not the only required dependencies?

Otherwise, I suggest you make a debug version and try that on your friends machine.

Use Dependency Walker on the target box to see what's missing.
