Hi @ivec

Is it normal that I needed to select the compiler manually?

No. but please select the C compiler also.

And how can I enable the use of a debugger to step through my program?

You need to install the Debugging Tools for Windows, included in the Windows SDK. Due to licencing, this is not possible otherwise.

Regards

@JonB Noooo... I did not understand that the enumeration of multiple paths in the Windows example referred to a list. Now I know :o) thanks.

@kshegunov said in App crushes when Qt core calls WinAPI's "DispatchMessage" function:

This address is rather suspicious. Please tell me you don't have global QWidgets?

No, I have only a dll with function

extern "C" CORE_SHARED_API QMainWindow * svCreateMainWindow() { return new MainWindow; }

(CORE_SHARED_API is __declspec(dllexport))

@kshegunov said in App crushes when Qt core calls WinAPI's "DispatchMessage" function:

Btw, 0xc0000409 is stack overflow, so be on the lookout for endless recursion.

As I said, QWindowsGuiEventDispatcher::processEvents() is called twice, and I believe those calls are on the same stack level (crush happens in the second call).

what is your suggestion about server app design ?

People usually refer to "server app" as "middleware" or "web application". There are tons of web frameworks and ORMs for various languages including Java and C# on "enterprise" side and scripting languages (pphp, python, perl, ruby, node.js). C++ is not really convenient language here. As for protocol, if you are not pursuing real-time data processing with lowest possible latency, it makes sense to use REST API on top of HTTP, so that on server side you have the most typical "web app" with ORM inside and REST outside, and on client side you can easily add web client if needed, and even if not, you get some additional convenience as compared to e.g. RPC over plain TCP

Hi,

An educated guess is that the second case is handled by the window manager (the decoration is not done by Qt).

One possible thing to do would be to check the screen resolution in your method and try to adapt to that.

@smhrambo deleting the *.pro.user file often helps when you do such moves...

@SGaist Thank you inform about me QtSingleApplication class. I will modify code and use QtSingleApplication.

There is a way to force an external window to become part of a widget, but the API isn't really meant to be used this way and there are multiple issues: https://bugreports.qt.io/browse/QTBUG-45275

@wrekler
ok. Im not sure what system buttons are.
But yes, its most likely there are bugs as its pretty involving across
platforms to support such decoration less window.

@JonB sorry for long reply
debug size is 29.5M
release size is 18.3M
Free memory always a more than needed PC have 16Gb ram. Also i checked swap, swap is newer used for last days. So problem is not here.
Next step i will check all dlls one by one in tes Win32 pure C application, maybe problem is here.

no cpecific initial code ... but as u can see a lot of dependencies.. In linux exist LD_PRELOAD key but there is no solution for windows i found.

Thanks for response, if i found any solution or reason i'll report it here.
Cheers.

@Natalya if your issue is solved, please don't forget to mark your post as such. Thanks.

For sake of completeness here is the answer from Qt developers (in case someone reads this and has the same issue):
http://lists.qt-project.org/pipermail/development/2018-April/032630.html

Unfortunately the reason why it was done in that way is still a mystery but it seems that the hook code can be safely removed

@aha_1980 i cleaned my old project build tried it again. The build is successful but when i try to run same error as mentioned above.

any changes : just uninstalled Qt5.9.1 .other than that nothing much.

this is my compiler tab if it helps any !!

p.. i have downloaded windows 10 SDK too now there is no triangle on msvc 32bit one but the problem still remains :/ .

Could you show full output of cmake? Did you install libsqlite3-dev package and cmake reports that sqlite is not found? That does not make any sense

Hi
Do you really need that many kits installed ??

Desktop QT 5.6.2 MinGW 32bit -> can make normal win32 apps in 32 bit. Run on win 10 64 bit too ( as 32 bit)
Desktop QT 5.6.2 MSVC2013 32bit. -> 32 bit, you must install compiler yourself. VS 2013 ONLY ( runs on 64 bit too)
Desktop QT 5.6.2 MSVC2013 64bit -> 64 bit, you must install compiler yourself. VS 2013 ONLY ( runs ONLY 64 bit )
Desktop QT 5.6.2 MSVC2015 32bit -> 32 bit, you must install compiler yourself. VS 2015/17 ONLY ( runs on 64 bit too)
Desktop QT 5.6.2 MSVC2015 64bit -> 64 bit, you must install compiler yourself. VS 2015/17 ONLY ( runs ONLY on 64 bit)
Desktop QT 5.6.2 for Universal Windows Patform 32bit Not a Desktop app. WinRT only app
Desktop QT 5.6.2 for Universal Windows Patform 64bit Not a Desktop app. WinRT only app

Sounds to me you can just use mingw. for both 32/64 bit unless you want app to be 64 bit ?

@raven-worx
I have also test the Registry Key changes, but doesn't have any impact.
By the way, I just realize that the XP build of my application is using ANGLE (because OpenGL is not supported) and Windows7 is using OpenGL.
By forcing Windows7 to use ANGLE, TeamViewer is working also with Windows7 :)

QCoreApplication::setAttribute(Qt::AA_UseOpenGLES); qputenv("QT_OPENGL", "angle"); qputenv("QT_ANGLE_PLATFORM", "d3d9");

Thanks a lot for your time

Regards

For example: QCameraImageProcessing

@VRonin said in QCA no Makefile:

also, if you are using MSVC you have to tell cmake to generate makefiles instead of project files. Pass the -G "NMake Makefiles" arguments to your cmake call

You sir, have saved me. I can't believe they don't specify that in the guide (it also uses MSVC, so idk why there wasn't the same problem).

I've run into some trouble while building, but that can/should be its own topic.

@VRonin said in QCA no Makefile:

Slightly related, is QCA supported and updated? The last thing you'd want is to use an out of date cryptographic library.

I normally use Crypto++ but libcrypto of OpenSSL is also very good (if you don't mind messing with C)

It is still active, looking at the the git (https://cgit.kde.org/qca.git/) the last commit was in 2017-09-30 (some months ago, but it isn't dead).
I had also been looking at Crypto++, but ended up settleing for QCA for no pacticular reasons. And I wouldn't mess with C, I'm still even just a C++ newbie afterall ;) QCA can also use OpenSSL btw.

Hello

I can't try with webview because i don't use QML in my project.

If I load the flash applet into Google Chrome, or Windows ActiveX Flash component, it works perfectly. :(

@kshegunov said in qmake install error detection on Windows:

target.depends = baseLibs

This was a very promising idea but unfortunately it looks like .depends does not work with other INSTALLS tagets

Hi,

One small correction: you can use Visual Studio 2017 with libraries built for VS2015, these two compilers are compatible (which is the first time two Microsoft Compilers are compatible).

Replying to myself:

The bugrepport said is is fixed for 5.10.1

https://bugreports.qt.io/browse/QTBUG-64121

And it can be made to work with correct folder permissions :

$ ls -ld /etc/config/ drwxr-xr-x 2 root root 4096 avril 1 11:15 /etc/config/ $ sudo chgrp pi /etc/config/ $ sudo chmod g+w /etc/config/ $ ls -ld /etc/cleandrop/ drwxrwxr-x 2 root pi 4096 avril 1 11:15 /etc/config/

resolving simlink doesn't helps

// resolve symlink // https://bugreports.qt.io/browse/QTBUG-64121 QFileInfo info(_configuration_file); if (info.isSymLink()) _configuration_file = info.symLinkTarget();

So I removed this fix, and fixed the folder permission and it worked.

@kshegunov Thank you for your suggestion I will try to follow it.

@mrjj

Ok. I have fixed it temporary by defining in the .pro file:
DEFINES += _ATL_NATIVE_INITIALIZATION

And also reported it https://bugreports.qt.io/browse/QTBUG-63772 . Thank you.

Nobody has replied, so I've entered it as a bug: https://bugreports.qt.io/browse/QTBUG-63901. I'll see what happens.

Nowadays the software renderer for WebGL works fine. I wonder if there is some easy way to detect if the video adapter is affected (probably intel && being "old") and if that's the case, to switch to software renderer, at run-time - maybe before initializing QApplication? in order to pass --enable-webgl-software-rendering parameter programmatically.

I've been digging around for the last couple of days trying to find the root cause of the issue and then it turned out that even the simplest Qt Quick application will crash with the same stack trace as long as it displays some text. Likewise none of the examples that are shipped with Qt (accessible through the Welcome -> Examples screen in Qt Creator) work, they simply crash on startup.

Would it be safe to assume it's a bug with Qt 5.9.1 built using MSVS 2017 (VC14.1)?
How do I even proceed now? Do I report it on the issue tracker?

Here's the relevant backtrace:

Hi, googling finds many with the same problem, for example here
Just guessing, but perhaps you could try some of the suggestions in there...

Thanks for the link.
It seems this issue doesn't even solved in Stack Overflow :(

Any way, I did some of the suggestions mentioned in it.

Installed all redistributable package of x86 (cuz I built my app using Qt mingw53_32) for 2012 - 2013 - 2015 - 2017 (I tested my app after each vcredist) Installed all redistributable package of x64 for 2012 - 2013 - 2015 - 2017 (I tested my app after each vcredist)

Nothing changed still see my app crashes without any logical reason!

Now I'm very sad because I can run my app only if I installed Qt on my machine which is impractical solution for deploying my app.

Ok. I have found the issue.

Since QT5_WRAP_UI macro is delivered as part of Qt5Widget packacge it is necessery to make a call to find_package (Qt5Widget) before issuing QT5_WRAP_UI call.

Ehh :D

yes, specify 32 and 64 for msvc2015
i was able to ignore the warnings
the kits i picked worked

Then, AFAUI, you have all what you need to continue. If implementing the proxy model looks daunting start by just a custom QAbstractItemModel with a QListView and once you have what you want you can go with the proxy and the shifting I suggested before.

Right, the library doesn't seem to be very Windows friendly. It assumes the pointers to GL functions resolved and available in global scope, which is not how it usually works on this platform. Moreover it seems to force ANGLE and OpenGL ES (or at least tries to) on Windows in the .pri file, but then is inconsistent in how it checks for that.

I'd say contact the authors and ask them to fix the Windows parts.
