QtOpcUa build error.

athyc

Hi

I'm trying to build the QtOpuUa lib with open62541 using qmake.
i'm using this guide https://blog.basyskom.com/2018/want-to-give-qt-opcua-a-try/
but when i run the mingw32-make .exe i get an error
I'm at a loss and don't know how to continue.

any suggestions?

@athyc have you tried the more recent blog from the link you posted?

athyc

Yes, same error it's the mingw32-make that's giving me issues :(

Pablo J. Rogina

@athyc so you did these steps below, right?

Execute the following commands in the “Qt 5.12.0 for Desktop (MinGW 5.3.0 32 bit)” shell

git clone https://code.qt.io/qt/qtopcua.git
cd qtopcua
git checkout 5.12
mkdir build
cd build
qmake ..
mingw32-make
mingw32-make install

could you post (as text, not an image please) the output where the error is showing up?

@Pablo-J-Rogina said in QtOpcUa build error.:

https://code.qt.io/qt/qtopcua

I found it more useful to use one of the backends they are using with qtopcua. The Qt interface didn't provide a server and was client only at the time. I am having success using open62541 as a server in my Qt console application I am developing. YMMV

Qt is now configured for building. Just run 'mingw32-make'.
Once everything is built, you must run 'mingw32-make install'.
Qt will be installed into 'C:\Qt\5.14.1\mingw73_64'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

So i did a reinstall of everything now, the error i get now is related to perl after i run mingw32-make.

All steps at show above.

athyc

Switched to Qt 5.12.2 mingw73_32 still same error.

@athyc

Project ERROR: Failed to run: perl

Do you have Perl installed?
If so, is it available in the path?
What's the output of following command:

perl -w C:\Qt\5.14.1\mingw73_64\bin\syncqt.pl -module QtOpcUa -version 5.12.8 -outdir

athyc

I just reinstalled Strawberry perl (32-bit) to ensure all versions are 32-bit.
I changed the path from a desktop folder to the QT\mingw folder and cloned the git link there.
It's running the mingw32-make now will update you when its done.

athyc

It works, got my first OPC connection now!
