ODБOï

Hi i, have compiled QtOpcUa and Open62541 for my opensource Qt 5.12

Now c++ side is can use QtOpcUa but in QML

import QtOpcUa 5.12 as QtOpcUa

output : QML module not found (QtOpcUa)

Did you add QT += opcua in .pro file?

ODБOï

@Ratzz Hello, yes, of course, as i said ' c++ side is can use QtOpcUa '

@LeLev

I referred https://doc-snapshots.qt.io/qtopcua/qtopcua-qmlmodule.html for QML.

Here is an example which may help you.

@Ratzz thx, i read this page.
i do
QT += opcua in .pro
and i do
import QtOpcUa 5.12 as QtOpcUa in qml

then in C++ i can use QtOpcUa but in QML i have error saying :

QML module not found (QtOpcUa)

there is no Opcua dir under my C:\Qt\5.12.0\mingw73_64\qml

@LeLev
U need to download and install the module as suggested here https://forum.qt.io/topic/67023/how-to-connect-to-opcua-server-using-qt-library/5

@Ratzz Thank you for the link, but i Already downloaded and installed QtOpcUa module like i'm repeating since the first post ...

I did qmake, make, make install

Now in c++ im able to create my opcua client.

My probleme is in QML i cant write import QtOpcUa 5.12 as QtOpcUa

Sorry if i'm missing something in that link you provided.

edit : When i do 'git Log' on the version of qtopcua i compiled i see this

SHA-1: 326bf6a1058d878b7891ee6d7078ed381c462df1

* Bump version number from 5.11.2 to 5.11.3

Are QML Types avalable in this version ?

Check your build folder: Do the QML files and QML plugins exist?

ODБOï

@JKSH Hi,
the 'plugins' folder contains open62541 .a and .dll
the 'lib' folder contains Qt5OpcUa .dll .a .prl
in the 'include' .pri and hraders

There is no qml folder

JKSH

@LeLev said in OPC UA QML Types not found:

That might be the issue. If I'm not mistaken, there should be a qml folder containing:

Some QML DLLs
plugins.qmltypes
qmldir

The last two files tell Qt Creator what modules you have.

For example, have a look inside <QTDIR>/qml/QtWebSockets/

ODБOï

@JKSH yes as i mentioned earlier i cant find opcua folder in C:\Qt\5.12.0\mingw73_64\qml

So what do you think is wrong with my QtOpcUa install ?

I know QML types came out with Qt 5.12

QtOpcUa i compiled version log is

SHA-1: 326bf6a1058d878b7891ee6d7078ed381c462df1
Bump version number from 5.11.2 to 5.11.3

Am i compiling wrong version ?
Doc of QML opcua Types says

Since:	QtOpcUa 5.12

I'm not sure, sorry. I haven't tried to compile a module in a long time.

I'll let someone more experienced take over.

@JKSH hi,
It looks like nobody used QML opcua types yet...
i did a double post
https://forum.qt.io/topic/97363/how-to-use-qtopcua-qml-types-windows-qt5-12-opensource/1
is there a chance QtOpcUa is directly avalable in the 5.12.0 LTS ?

D'oh! I didn't notice this part earlier.

You were compiling from the Qt 5.11 branch, which did not have the QML types.

Qt 5.12 has just been released, so have a look at its source code.

@JKSH hi,
but on github i select 5.12 in branch dropdown menu
https://github.com/qt/qtopcua/tree/5.12

i clone it, then if i do 'git log' i see the same thing

SHA-1: 326bf6a1058d878b7891ee6d7078ed381c462df1
Bump version number from 5.11.2 to 5.11.3

i don't understand why.

That's the Qt 5.11 branch.

Call git checkout v5.12.0

ODБOï

@JKSH Thx!

ODБOï

@JKSH one more question please.

Can i just update (git checkout v5.12.0) my QtOpcUa and re-do

qmake
make
make-install

directly or i have to delete my current (5.11) QtOpcUa installation ?

edit :
and git checkout v5.12.0 gives me error

error: pathspec 'v5.12.0' did not match any file(s) known to git.

@LeLev

Did you do git fetch before?

Depending on your remote name, you'll probably need git checkout origin/v5.12.0.

PS: Don't forget to remove all build results from to old Qt version before building new.

Edit: It seems that github repository is outdated. Please clone from (or add as remote) the official repository http://code.qt.io/cgit/qt/qtopcua.git

Hi,

Github is to be considered a backup mirror. It might (as you discovered) be a bit outdated with regards to current state of https://code.qt.io.
