Hello Forum,
I tried to compile qt6.5.3 from source and it fails with:

cmake --build . --parallel

ninja: build stopped: subcommand failed.

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?

[semlanik]

Addressed here: https://codereview.qt-project.org/c/qt/qtgrpc/+/488623 backported to 6.5 lts.

[SGaist]

Hi and welcome to devnet,

I haven't built that module yet but which version of grpc are you using ?

[SiGa]

Thank you for the answer.
I checked out the head of the "origin/6.5.3" of the qt6 repository.

Update dependencies on '6.5.3' in qt/qtgrpc

You mentioned that you don't build this module. 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?

[SiGa]

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.

[SGaist]

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.

[SiGa]

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.

[SGaist]

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

[SiGa]

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

How do I manually configre the qtgrpc submodule?
qtbase folder contains a configre script, but qtgrpc does not.

[SGaist]

cd "somewhere out of Qt sources"
mkdir build_qtgrpc
cd build_qtgrpc

@SiGa the cherry-pick of this commit https://codereview.qt-project.org/c/qt/tqtc-qtgrpc/+/514999 is missing in 6.5. There are some more commits.

I can not understand how I should figure out the qtgrpc version from this.

[SGaist]

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

[SiGa]

@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.
