OPC UA QML Types not found

ODБOï

@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

Ratzz

@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

ODБOï

@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 ?

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

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

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/

@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

URL is https://code.qt.io/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.

@aha_1980 Thank you! now i got qtopcua 5.12!

Do you mean i have to delete for exemple : Qt5OpcUa.dll / Qt5OpcUad.dll
from my C:\Qt\5.12.0\mingw73_64\bin dir before i reinstall newer version ?

@SGaist thanks
this is good to know for the next time

I'm not sure how you did build the module before. Did you use shadow building? Then I'd just wipe the shadow build folder. Or did you build inside the source dir? Then a git clean -dfx removes everything that is not under version control.

Deleting the DLLs will not hurt, but they should be overwriten by make install. More critical are the things I mentioned above, e.g. old Makefiles.

@aha_1980
i did :

git clone
cd qtopcua && mkdir build && cd build
qmake ..
mingw32-make
mingw32_make install

so i can only delete my build folder right ?
thx
