Why are there no mingw-w64 Qt x64 bundles?

xtemp09

Why do the developers keep ignoring gcc-x64? I've compiled Qt with TDM-GCC, mingw-w64 many times, it works fine.

Hi and welcome to devnet

It is merely a trade-off issue IMHO. MinGW 64 bit is working, but would be another additional compile run binding capacity. Respectively, there would be a bunch of different compilations required because of different possible options. There are some external sites providing complete MinGW 64 bit compiles for Qt libs.

Been there, tried that. Qt64-NG was closed, Qt-x64 was abandoned.
Maybe, the developers just don't want to support opensource projects.

I can't find the original source now but it was basically due to resource constrain. they analysed which binaries were downloaded more frequently and cut the rest to save on machine resources required to deploy

Pretty much the opposite, you can always compile it yourself

@xtemp09 Possibility of x64 MinGW packages is considered for 5.9

You can read the (quite lengthy) recent discussion about pre-built packages on the development mailing list. It boils down to how many configurations it is practical to maintain. Especially on Windows there are multitude of available compilers, versions and bitness. The move to x64 for MinGW will happen. There's just question of how to do it and not explode the number of pre-built packages. To make it feasible some need to be cut down, and these will likely be the older versions of MSVC, since another one is already on the horizon.

I think I found the solution - clang. This compiler is used to compile Qt on OS X, I think it's a good idea to use it on Windows as well. It will facilitate its support on Windows.

Konstantin Tokarev

@xtemp09 There are no prebuilt Clang binaries for Windows either so it solves nothing. Also, Qt does not support clang on Windows yet, while MinGW 64 works fine, packages are shipped in MSYS2

@Konstantin-Tokarev I am downloading it now! Thank you! The msys2 package works like a charm
