Build qt6.5.3 from source fails due to protobuf

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
/path/to/your/Qt/bin/qt-cmake /path/to/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.

SGaist

@semlanik would you have the corresponding public patch link ?

-- Configuring incomplete, errors occurred!

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.
