Qtweb, problem with QtWebEngineProcess

[goluckyryan]

Following up on a closed post on Qtweb, don;t know how to reopen the post.

The root is compiled from the source, version 6.28/05, with

>cmake ../root_source -Dwebgui=ON -Dqt6web=ON -Droot7=ON -DCMAKE_CXX_STANDARD=17

I install Qt6 using apt.

compilation of the qtweb is OK. But when I run it. it shows

Could not find QtWebEngineProcess
Aborted (core dumped)

I have the following qt6 packages installed

qt6-3d-assimpsceneimport-plugin/jammy 6.2.4+dfsg-1 amd64

QtWebEngineProcess

Hi,

This is special executable which is provided with Qt WebEngine.

See Deploying Qt WebEngine Applications | Qt WebEngine 6.6.1

On my OpenSUSE it is in /usr/lib64/qt6/libexec directory.

It is provided by qt6-webengine package.

[goluckyryan]

Oh, I found the solution.

I though all qt6 packages are with the name

qt6-XXX

like the webengine, they are

qt6-webengine-dev
qt6-webengine-dev-tool

But, in Ubuntu 22.04 qt6-webengine was removed from the repository, and moved to

libqt6webenginecore6

after sudo apt install this package, qtweb can run!!
