Basic fix for QT 6.x applications

Unread post by K4sum1 »

The modded dlls come from dmginc's post on this thread, but the original author uses a wack file sharing site, and I've done a slight mod, so I've reuploaded it on the forum. I've also uploaded patches for 6.3.0 and 6.2.2 to this post, but they can also be found in the previous link.

In the attached .zips are the dlls for getting QT 6.2.2, 6.3.0, and 6.3.1 based applications working. Copy and replace any files in the application directory, and it should work. If you have any problems with QT 6 applications that don't have specific posts in this category, reply and I may be able to help.

Thank you for the compatibility fix, but I have some issues tho..

1. Dolphin Emulator does not start at all, even replaced all files.. (It's just completely silent there)
2. Can you add support for Qt 6.4 and later? (Since PCSX2 uses newer Qt version on their updates)

Anyways, keep doing.

PCSX2 past the version I posted about in this category is very unlikely to work on 7, unless someone manually creates a patch, then it might work. There might be a QT 6.4 patch in the thread above, I'll take a look and update the post if there is one.

I'll also take a look at Dolphin.

Dolphin be kinda weird, it gives a BluetoothApis.dll error with a very early QT6 release. I guess just use the 16380 beta or get the last build before QT6, 16391.

I'm not sure if QT6.1 needs 10+, but I found a QT6.1 application that runs on 7 stock, so I pulled these files from it to make a patch in case it's needed.

dmginc released a 6.4.2 patch, and same website that hates Firefox. So I downloaded it with Chromium, and reuploaded it here. I also did the slight mod. (Added a different folder for qwindows.dll that some applications use.)

About PCSX2, there's a Qt6.2.2 backporte version of the new PCSX2, which should be covered by existing Qt6 compatibility hacks: https://github.com/Darthagnon/pcsx2-win7

My fork, as the original master was deleted, and I had to contact the author to get it restored. I also have the final binary from the original master's Github CI somewhere, too. I've spoken with the author of this backport, and he said the patch should be portable to newer versions of PCSX2, just needing some adjustments.

That said, I'm not a Qt developer. I can just about figure out how to build things.

Why QT? WxWidgets is objectively superior, and the PCSX2 team maintains both builds.

They fully removed wxWidgets by Dec 2022 (Source), only the Qt GUI remains (unless there's some sort of legacy build I don't know about). As far as the end user is concerned, it seems Qt has a slightly easier-to-use GUI, but I am miffed that they ditched older Windows versions for that.

Maybe a good fork would be to update the core of the WxWidgets release.

Anyone know if there's a Qt 6.3.2 mod, or if any of the related mods are usable on Qt 6.3.2? I'm experimenting with Literature & Latte's Scapple, which is made in Qt 6.3.2.

It's got:

Code: Select all

Qt6Core.dll
Qt6Core5Compat.dll
Qt6Gui.dll
Qt6Network.dll
Qt6OpenGL.dll
Qt6Positioning.dll
Qt6PrintSupport.dll
Qt6Qml.dll
Qt6QmlModels.dll
Qt6Quick.dll
Qt6QuickWidgets.dll
Qt6SerialPort.dll
Qt6Svg.dll
Qt6TextToSpeech.dll
Qt6WebChannel.dll
Qt6WebEngineCore.dll
Qt6WebEngineWidgets.dll
Qt6Widgets.dll
Qt6Xml.dll
Honestly not sure how many of those it actually uses, as it is an offline minmapping software...

Weirdly, FBReader is made in Qt6, but runs fine on older Windows if I recall correctly.

6.5.1 is out, same site that I hate, but at least it works in Firefox now. Still mirroring it here because I foresee it breaking in older browsers in the future.

Not quite sure what that is, but if the PY in the name is what I think it is, you might need the Python fix here too.

rpcs3 has now been upgraded to qt6, and using the basic fix on the new version doesn't at all and gives out an error.

Either wrong QT6 ver or they use a special version. Maybe compiling a version with the QT6 patches and using those dlls for later releases could work.

For Qt6 RPCS3, more changes are needed, already done by Alan_A/okt01475 here: https://www.patreon.com/posts/rpcs3-0-0-29-qt-88446670

There's also a new project to port Qt 6.5.3, 6.6.0, 6.6.1, etc. in a more complete way to Win7: https://github.com/crystalidea/qt6windows7/releases

It has already been successfully used to backport PrismMC, see here:

I've been meaning to test these later QT dlls, but haven't gotten around to it.
