Hello Forum,
I tried to compile qt6.5.3 from source and it fails with:cmake --build . --parallel [714/11191] Check QtWebEngine support QtWebEngine will not be built: node.js version 12 or later is required.

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

Hi and welcome to devnet,
I haven't built that module yet but which version of grpc are you using ?

Thank you for the answer.
I checked out the head of the "origin/6.5.3" of the qt6 repository.Commit: 0a1e4f22cdf6a099d01e4a32aace997b874c4d42 Parents: 96287a77e8645d0010695d2544e105ee6e9e4dbe Author: Qt Submodule Update Bot <qt_submodule_update_bot@qt-project.org> Author Date: Mon Oct 16 2023 05:36:08 GMT+0200 (Central European Summer Time) Committer: Qt Submodule Update Bot <qt_submodule_update_bot@qt-project.org> Committer Date: Tue Oct 17 2023 05:36:33 GMT+0200 (Central European Summer Time) Update submodules on '6.5.3 in qt/qt5' Change-Id: If7addaf2048bba0ba914ac94c18cbc78f3662b83 Reviewed-by: Qt Submodule Update Bot <qt_submodule_update_bot@qt-project.org>The qtgrpc module is at "origin/6.5.3" | "v6.5.3".

Is this not commonly build and used one?
I don't need to use grpc, and could ommit it during the build.
Since I saw no commands for ommitting certain modules I will look into the configure scripts.
Do you know how to ommit a certain module? -
configure had a help parameter which gave me the instructions on how to adjust my build to my needs.
../configure -hWhen I only build qtbase it works.
../configure -cmake-file-api -submodules qtbase -prefix /install/pathI could not find a qtwidgets submodule, thus for now I assume that it is part of qtbase.

I have the config.summary from trying to build the qtgrpc submodule, with its dependencies.

qtbase folder contains a configre script, but qtgrpc does not. -

@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. -
