Problems encountered when I use vs2022+qt6 static compilation

[Christian Ehrlicher]

@injertao said in Problems encountered when I use vs2022+qt6 static compilation:

I used -static

'-static-runtime'

These are two different kind of things. You compile with a static runtime (MT) therefore you also have to compile Qt with a static runtime as @kkoehne told you.

[injertao]

@Christian-Ehrlicher I successfully built QT using -static -static runtime, and vs2022 successfully generated a simple exe, but this exe cannot run normally on win7 x64,

---

QtWidgetsApplication1. exe - System Error

---

The program can't start because api-ms-win-shcore-scaling-l1-1-1. dll is missing from your computer. Try reinstalling the program to fix this problem.

---

OK

---

How can I further solve this problem? I hope my exe can run without any explicit DLL.

thanks u

Please help me.

Hi, the error "No space left on device" means your C: drive is full :-(
Try removing some stuff

[injertao]

@hskoglund I'm stupid, but my C drive has 100GB, isn't that enough?

[JonB]

@injertao
Yeah, that really should be plenty :) Re-verify you still have that much space left. It's possible that error message is "misleading". Can you manage to copy the file in question from/to the exact paths in the message? Is there some issue creating the destination path?

Please note Qt 6 only supports Windows 10.

[injertao]

@JonB Thanks, I'm rebuilding(This may take up to 2 hours), but my problem is still that I can't run my EXE on Windows 7 X64 and shrink it perfectly

Well, you're asking for a static debug build + static release build of all of Qt. If you combine static with debug, executable sizes add up quite fast :)

Do you really need the debug build?

@kkoehne thanks
What is the last version to support Windows 7 x64?
I have a strange problem.

I have 100GB on my hard drive

Qt 5.15

have 100GB on my hard drive

Check your file system. Is there enough space left?

[injertao]

@kkoehne thanks
My operation is in VMWARE, there is only one C drive, I am sure it has 113GB left

[hskoglund]

Hi, iperhaps iit is because your host OS has no space left (even thougjh your C: drive inside VMWare is ok)
This can happen when you tell VMWare to dynamically allocate space for the C: drive (i.e. not a fixed size C:)

[cristian-adam]

Note that Qt6 applications, even compiled statically, won't run on Windows 7.

If you really want to achieve this, you need to patch Qt6, see details at https://forum.qt.io/topic/133002/qt-creator-6-0-1-and-qt-6-2-2-running-on-windows-7

If you run out of disk space, you can set the NTFS compression flag of your build directory.

@hskoglund
I confirm that the disk capacity of the host is sufficient

thanks

@cristian-adam
Thank you, I will make further Chan
