Do you use Visual Studio as compiler? That environment has such a tool embedded

Hi,

No there's not. You can use the OpenLDAP library to interact your your LDAP server.

At some point, there was the Luma GUI application.

@Ace04 said in Unresolved external symbol _strerror_r error while executing libcurl with QT:

LIBS += -L"$$PRO_FILE_PWD/dependencies/SSL/lib/" libcrypto.a libssl.a

Your LIBS lines are wrong.

Correct would be: LIBS += -L"$$_PRO_FILE_PWD_/dependencies/SSL/lib" -lcrypto -lssl (Add -l, omit lib... and .a.

Also, convert all backslashes to forward slashes.

Also, remove all trailing slashes from the paths (INCLUDEPATH and LIBS)

Regards.

There should also be a folder with the tests that ran. That's the one I am suggesting to check.

Note that there seems to be some mixing of forward and backward slash which might explain the failure. Use all forward slashes when giving parameters.

Unfortunately WinCC OA 3.15 requires no later than QT 5.5.1, MSVC 2013 and Win 64bit

I have downloaded a different file from https://download.qt.io/archive/qt/5.5/5.5.1/ and that does indeed seem to have resolved the compilation issue :)

I am now getting an error at runtime but could be something daft so I will look into more.

Thanks

@jsulm I already use MockOpcConf _selectedConfValid;

But I have got the other objects.

Sorry for the post. It seems that my CMakeLists was wrong and hence the building of my program was failing.

In addition to the Qt libraries, I have got Qt5OpcUa.dll and open62541_backend.dll, but it won't work.

Fix this by copy / pasting a sample project into QuickQanava root after forking QuickQanava on GitHub. Rename the .pro, .pro.user and the folder. In the .pro file, put in the new path to the apparent .pri file.

It builds and runs now.

@Christian-Ehrlicher Thanks for your reply. I have used a newly installed machine with only qt 5.14 compiled, and I did not change any source code so it is strange if I by error have somehow included any Qt4 headers.

I see that the build also fails at https://github.com/KDAB/GammaRay (ERROR: could not open HSTS store at 'C:\Users\appveyor/.wget-hsts') but I guess this is unrelated.

Best

I understand your frustration but there's nothing we can do here. Qt just provides tools. Someone just made a poor use of them. I'm a game engine programmer myself so I can tell you that it can be hard to diagnose these types of issues and it is often hard to even know they exist. It might be a bug, bad network design or a simple case of "works on my machine". Sometimes it's an entirely different team that makes a crappy launcher for otherwise good game or vice versa.

Try to contact the creators. Developers often don't read forums but there's a lot of them on social media like twitter or reddit. Just be polite and keep your head cool. They're people too. Try to imagine how you'd like to be approached when something you made doesn't work for somebody ;)

Hi and welcome to devnet,

You should take a look at the QtPositioning and the QtLocation modules.

Hi and welcome to devnet,

That's a question better asked to the CERN folks.

I solved by creating a stored procedure then passing the values to a json object. Created a trigger on Insert then execute the procedure. In my app it detects the source with switch case. I followed some examples and implemented to my needs.

@lee64456546 Have you tried Doxygen?

Hi all,
Someone please reply to this query.....still I'm not getting the result.

The problem was solved by changing the tread to pthread
