Creating 64 bit version of my application?
-
Hi,
I am successful in developing my application with Qt 4.8.1 with MinGW compiler for 32 bit Windows.
Now I want to support 64 bit version of my application too.
I want to move on to the latest version of Qt i.e. Qt5.2 and already have downloaded the source files.The problem is that I dont know whether I have to build the entire Qt or just the dll's that I am using - QtCore4.dll QtGui4.dll and QtNetwork4.dll?
Since I already have the source code for my application I just need to compile it in 64.
So for building my 64 bit application do I only need to build the required modules of Qt?
If yes then how do do this?
Please forgive me if I am asking a basic question, but this is my first time with application development and hence am looking for some help... -
Hi,
To build a 64bit application you need to either download or build a 64 bit version of Qt.
You can find "here":http://www.tver-soft.org/qt64 unofficial packages of Qt that includes a MinGW 64 bit version
Hope it helps

Thank You SGaist for your reply.
Qt for my compiler is not available, I have to build my own Qt.
But my question is that whether I need to build all of the Qt modules or just the ones I am using? -
Depends on your future development tasks, so it's really up to you
