Windows.h errors when including QtGui but not QtCore

patrickkidd

I am getting the following error when including QtGui. Including QtCore works just fine:

Any idea how to fix this compile error?

Seems like this sort of thing usually as to do with platform-oriented defines or config settings. But it's been a long time since I've done serious windows build system work.

Thanks!

@patrickkidd What exact compiler and Qt versions do you use?

patrickkidd

@jsulm Visual Studio 2019 (v142), qt-5.15.1 installed from qt.io installer, Windows 10 Pro with all latest updates.

jsulm

@patrickkidd Can you reproduce this issue with a minimal application including QtGui module?
Your qmake file looks quite complex, could be that something there is causing the issue.

The age-old question. I suppose I was hoping for it to be well-known enough to have a simple answer. I'll see what I can do with a simple example.

@patrickkidd said in Windows.h errors when including QtGui but not QtCore:

prsht.h(609): error C3646: 'hdr': unknown override specifier

Please take everything I say here with a grain of salt, and fact-check me aggressively, because I am definitely more of a Linux developer than Microsoft Windows.

However, I think this might be more of an issue of "general usage of Win32 in C++" than anything particular to Qt. Which in today's case (your case, @patrickkidd ) is likely to be good news, because the universe of people who know about this error is bigger than the universe of just Qt users.

To my surprise, the EXACT error (with line numbers and all!) has many hits on a web search: "prsht.h(609): error C3646: hdr: unknown override specifier"

Maybe these help?

(they all suggest either adding particular #include lines, or moving certain #include lines higher up in your files. this is a "game" i remember not-so-fondly from my Win32 days)

patrickkidd

@KH-219Design Yeah, I've dealt with this problem and its derivatives plenty of times over the years. As indicated in the posts you link, it usually has something to do with getting the order of windows.h and other headers (QtGui in this case) right. Less likely a stray macro. Though no luck in this case yet.

patrickkidd

I was able to solve this for this project by including Python.h before QtGui. Including windows.h should have fixed it, but it doesn't. Oh well.

KroMignon

@patrickkidd I often got suck kind of problems with Windows and Qt. The solution I found is to use #include "qt_windows.h" instead of #include "windows.h"

hope this helps

Interesting. I was not aware of this header. But it also didn't solve it for me. Including Python.h did. No idea how that is so.
