@Marcel-Thiele said in Build qt6.5.3 from source fails due to CMake Error:

Same problem here Ubuntu 24.10

why are you so keen on LTS versions if you don't even use one for your Ubuntu (which is 24.04) ? :))

The online installer provides 5.15.2.

It also provides a more recent version of Qt Creator which might work better than the one you are currently using.

Qt6 is a whole new library. There's no way I'm going to try to build a Qt5 app with it. There's a 0% chance it would build. So I went through the trouble of figuring out how to apply those patches.

The link above is to a confusing web tool, but I eventually figured out that you can download the patches. Both of them are identical, so only one is needed. But the patch can't be applied to Qt5 automatically, so you'll have to manually edit the file.

If you downloaded the "qt-everywhere-src-5.15.2" archive, the file to patch is:

qtbase/src/plugins/platforms/cocoa/qiosurfacegraphicsbuffer.h

Somewhere before the line that says QT_BEGIN_NAMESPACE, insert this line:

#include <CoreGraphics/CGColorSpace.h>

Then configure without qtwebengine:

./configure -opensource -confirm-license -skip qtwebengine && make -j 8

@oblivioncth I can confirm that this was fixed in 6.0.1

@MLeone said in Using qmake and it can't find qtquickcontrols2:

@SGaist I create a folder inside the src folder, called qt-biuld. Then I do
-prefix ../qtbase

You are installing (make install) into qtbase, so it's not a clean build. Pick a different install target directory, like $PWD or something entirely different.

@oblivioncth said in Building 5.12.1 32-bit static Qt for MSVC on Windows 10: The system cannot find the file specified (qgltf5.pdb).:

C:\Engineering\Development\Qt\Tools\QtCreator\bin\jom -j 8

I wanted to keep the versions for the standard and static versions consistent, but its not like it would really matter since its just a small revision difference. So, I attempted to build 5.12.3 this time and while I was at it I grabbed the dynamically linked version of 5.12.3 from the maintenance tool as well.

This time I ran the Visual Studio Native Tools command prompt as an administrator since I figured that had a shot at mattering even though I didn't see it mentioned anywhere and wasn't doing this is a UAC protected directory.

And... it built completely with no issues and I was able to produced a statically linked version of the app I'm working on like I wanted to. I don't know if there was a bug in the 5.12.3 source, if it actually was running the prompt as administrator, if there was just a simultaneous access issue with some of the files/tools on the last run, or if it was just a fluke, but everything works fine now.

The build ended on the same two lines but succeeded in copying qgltf.pdb instead of not finding it and the process took much longer than the previous attempt, so I'm guessing that there were errors earlier in the process that didn't stop the build script so I didn't catch them.

@jsulm said in Qt creator cannot successfully start app built with custom built qt bundle on windows:

@farta clone means here cloning from Qt repository (git clone)

Thank you.
I never clone it from Qt repository.

Also note that Qt 5.4 was released before VS2015 came out, you should use at least Qt 5.6 with this compiler

@no_ideaw Can you show your pro file?
Also did you run qmake and rebuild your project after changing Kit to "Android for armeabi-v7a"?

You're welcome !

I'm pretty sure not all these packages are necessary but at least you have it working now :)

You have here a list of the modules and their state.

QtWebkit as been deprecated and removed.
QtQuick1 as been deprecated and removed

You can still build them from sources but you have to clone them specifically.

In my case the package extracted were not complete so I had to extract it again and finally it was working

i still think there is simpler explanation for your issue.
The linker can't even find the lib file specified.
Are you really sure that the libs are in "C:\source\icu2\lib"? And not in a release/debug subfolder, etc.?
