C ++，Qt - 如何摆脱dll依赖？

Question

I have compiled my Qt application and now have the following question - now my built project requires QtCore4.dll and QtGui4.dll to be located at the same folder where the .exe file is. (I built my project using MSVS2008 with Qt addon)

Q:

Is there any way to combine my final application with these .dll files so that they make one large .exe -file? (I simply don't want to have another bunch of dll files with my release - app)

Thank you.

Answer 1

You need to build and link to Qt statically.

Edit: Here's an updated link to at least similar information .

Answer 2

Bundle them into a self-extracting .exe (eg using 7zip) which extracts all files to a temporary directory, runs the program, then deletes the files after the program exits.

This will be easier, less time consuming and less legally constraining than statically linking Qt as previously suggested.

Answer 3

Of course you could statically link someway. But the point of using DLL should be to make program smaller (both on disk and in memory, if other apps are using Qt libs of course)... DLL such as those should be systemwide so that other apps needing them can use them. Basically you have to say to people wanting your program to work, to install the Qt framework.

Deploying the other way is explained here , read the part related to Static Linking.
