[Releasing] Binary packages for Qt 5.4 / Qt WebEngine 1.0

[Knight Andrew]

Hi,

>From a CI perspective, I believe you are asking for a testconfig which runs under the win-msvc2013-Windows8.1-x64 nodes, but builds under the x86 "vcvars" command prompt.

This is already done for packaging machines building Windows Phone mkspecs (ARM and x86), and must be done for CI once Windows Phone is there as well. In all WinRT cases, the OS is 64-bit while the command prompt is the "default" x86 one.

So, you are not alone in this requirement. It's a matter of changing the configure scripts to allow building from a non-x64 command prompt within the 64-bit environment. If we made this a hard requirement across the board, we could even drop the win-msvc2013-x86 stage *nodes*, and just make sure the relevant stages are executing with the correct (x86, ARM, X64) vcvars.

Cheers,
Andrew

Subject: [Releasing] Binary packages for Qt 5.4 / Qt WebEngine 1.0

Hi all,

As you might already know, Qt WebEngine for Windows can only be built on a 64bit machine. This is a strict requirement imposed by Chromium. However Chromium used to build 32bit binaries only for quite a long time, and Windows 64bit support has only been added very recently.
Further requirements on Windows are ANGLE and msvc2013.

Matching this with our packaging infrastructure leaves us with a single build to produce packages: win-msvc2013-Windows8.1-x64_ANGLE
Assuming that the x64 in the name resembles both host and target operating system.

This also means that we will not have 32bit Windows packages that include QtWebEngine. And I think this is something we might want to change.

I believe the only change necessary to allow building 32bit Windows packages is to change the configuration win-msvc2013-Windows8.1-x86_ANGLE to be actually running on a Windows x64 installation. Do you think this change is feasible?

Best Regards,

Zeno Albisser
