How to build 64bit Qt 5.3 for Windows 7 x64? Is there any differences between builds with MinGW-w64 and MSVS?

Question

Maybe this question is very simple and was asked a lot of times, but, despite that I googled a lot, I can't find step-by-step instructions for building Qt. All of them either for Qt4 or contains some bugs. I need 64bit version of Qt for Windows 7. How it can be done?

Answer 1

I think that qt docs on building from source and requirements look like step-by-step instruction on how to build Qt5. If you follow the steps thoroughly, you'll be able to do this.

In particular your issue "Can't find icuin.dll" tells that you didn't install icu. You have an option to either install it, or specify option "-no-icu" when running configuration script.

If you build MSVS version, you should build Qt form MSVS x64 console, that you can find in Start menu->programs->MSVS folder. In this case you will not have to set some environment variables like QMAKESPEC, etc
