    configure had a help parameter which gave me the instructions on how to adjust my build to my needs.

    ../configure -h
    

    When I only build qtbase it works.

    ../configure -cmake-file-api -submodules qtbase -prefix /install/path
    

    I could not find a qtwidgets submodule, thus for now I assume that it is part of qtbase.

    By "I haven't built that module yet", I just mean that I personally did not build that module.

    What I requested was not the version of the QtGrpc module but the version of grpc itself.

    QtWidgets is part of qtbase.

      I could not figure out the version by examining the qtgrpc submodule.
      Then I installed 1.58.1-1 onto my machine.
      Is this the version you are asking for?
      Build again and it still fails.

        Can you manually try to manually configure qtgrpc to see what the summary tells you ?

              Maybe I have checked out the wrong commit for build or some other beginners mistake, which I am not able to spot.
              First I tried with origin/6.5.3 and then the label v6.5.3, both fail with very similar, if not the same, protobuf error.
              I followed the building guide: https://wiki.qt.io/Building_Qt_6_from_Git

              Is this an actual bug that should be reported in the bug tracker?
              Has anyone advice or additional information on how to build from source?

                    @SiGa I have never asked for the QtGrpc module version. I requested the grpc version.

                      @SGaist
                      Okay, currently I have grpc 1.59.2-1 installed.

                      Previously I had following version installed.
                      @SiGa said in Build qt6.5.3 from source fails due to protobuf:

                      I could not figure out the version by examining the qtgrpc submodule.
                      Then I installed 1.58.1-1 onto my machine.
                      Is this the version you are asking for?
                      Build again and it still fails.
