@abhishek999 What exact Qt version did you use to build QGIS? Is it the same you're using to build the application?

[abhishek999]

@jsulm i am using qt 5.15.2

[jsulm]

@abhishek999 You did not answer the second question.

[abhishek999]

@jsulm
qt version 5.15.2
qgis version QGIS 3.34.12

@abhishek999 This also does not answer my question.
Again: did you use same Qt version to build QGIS as you use to build your app?

And why do you have this in your pro file:

INCLUDEPATH += C:/Qt/5.15.0/msvc2019_64/include/QtXml

There is no need to add Qt include folders to the include path, you just have to enable the Qt modules you want to use in "QT +="

@abhishek999

You say you are using Qt 5.15.2 but your include path says Qt 5.15.0? Which one is correct?

And post code as text, don't post images please.

[abhishek999]

@jsulm i did not understand can you please tell me wich version i have to use if i am using Qt 5.15.0 and along with download link.

Use same Qt version to build QGIS and your app...

It doesn't matter which version exactly, as long as it works... The important thing is that you use the same to build QGIS and your programs.

@Pl45m4 @jsulm
QGIS is built in qt 5.15.13
but this version is not showing in qt installer 5.15.2,5.15.1,5.15.0 are available in installer how i download this version

[jsulm]

@abhishek999 said in QGiS Windows Source Build:

how i download this version

You need a commercial license for that version or you build that version by yourself. But it should also work if you use Qt 5.15.2 for your app.
Was QGIS built using MSVC or MinGW?

[xanthas]

@jsulm QGiS which version should be worked with Qt 5.15.2?

[jsulm]

@xanthas See https://github.com/qgis/QGIS/blob/master/INSTALL.md
Yes, 5.15.2 is supported.
