Building Qt 6.5.0 from source with GStreamer enabled

[aleksandar14]

Hi, I am trying to build Qt 6.5.0 from source on windows 11 with enabling gstreamer.
When I run

..\qt-everywhere-src-6.5.0\configure --help

I get this for enabling gstreamer:

And I try to configure Qt with the following command:

..\qt-everywhere-src-6.5.0\configure -release -platform win32-g++ -opensource -confirm-license -make libs -nomake tools -nomake examples -nomake tests -prefix C:\output\qt6.5.0 -gstreamer

And I get the following error:

-- Windows 10 SDK version:
CMake Error at C:/Sources/qt-everywhere-src-6.5.0/qtbase/cmake/QtProcessConfigureArgs.cmake:299 (message):
  Invalid value '' supplied to command line option 'gstreamer'.

Also I tried with -gstreamer 1.0 or -gstreamer 1 but got the same error.
Any idea what I am doing wrong?

Hi and welcome to devnet,

Did you build and install GStreamer for Windows ?

[aleksandar14]

@SGaist Hi and thank you.
I have installed GStreamer MinGW 64-bit runtime installer and development installer.
Do I need to build GStreamer from the source and specify the path in the configure command?

[SGaist]

@aleksandar14 if you have the development files, it should be good. Did you point the configure script so it can find GStreamer's development files ? Also, are you using MinGW as well to build Qt ?

[aleksandar14]

@SGaist No, I didn't specify any paths to the configure script about GStreamer's development files. Should I pass the path on the configure command or I should add the path in some file?

Also, yes about the compiler, If I run the configure command without -gstreamer in the config summary I am getting Compiler: gcc 13.1.0.

I tried passing it like this and same error occurred:

-gstreamer C:\gstreamer\1.0\mingw_x86_64\bin

Qt 6 use cmake as build system. You can't just put a path somewhere expecting it to be picked up.
