OPC UA QML Types not found

@LeLev said in OPC UA QML Types not found:

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

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 ?

@LeLev said in OPC UA QML Types not found:

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 ?

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

@JKSH Thx!

@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Edit: It seems that github repository is outdated.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 It might (as you discovered) be a bit outdated with regards to current state of https://code.qt.io.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

aha_1980

@LeLev Correct! :)

Hello
Dear @aha_1980 and @SGaist do you please know why qtopcua 5.12.0 cant find open62541 backend ?

With my qtopcua 5.11 i do

qmake c:\users\lagayev.meca\documents\lib\qtopcua -- OPEN62541_PREFIX=c:\users\lagayev.meca\documents\lib\
open62541 OPEN62541_INCDIR=c:\users\lagayev.meca\documents\lib\open62541\build OPEN62541_LIBDIR=c:\users\lagayev.meca\documents\lib\open62541\build\bi
n

output is

Qt Opcua:
  FreeOpcua......................... no
  Open62541......................... yes
  Unified Automation C++ SDK........ no

But with qtopcua 5.12.0 output is

Qt Opcua:
  Open62541 .............................. no
  Unified Automation C++ SDK ............. no
  Support for namespace 0 NodeId names ... yes
  Namespace 0 NodeIds generator .......... no

i made new post for this..
Thank you

Qtopcua Build process has changed, now Open62541 is included - see Building Qt OPC UA with open62541
