3021 – error: call of overloaded 'tqDebug(TQCString&)'

By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

Description Roman 2019-06-26 15:56:00 CDT

On the assembly of the example "widgets" the assembly ends with an error:

http://dpaste.com/0TX8FGR

Since there is no function:
Q_EXPORT void tqDebug( const char *);
ends with an error...

You need to either add a new function to tqt3, or change the function call in the example.
Something like that:

tqDebug (output, 0);

File: examples/widgets/widgets.cpp

System Gentoo, gcc version  8.3.0. TDE - 14.1.0.

Hi Roman,
is this still valid?
There was such problem for a very short while around the time of this bug report when doing some improvement in tqt3. But it was almost immediately fixed.
What is the status now?

Comment 2 Roman 2019-09-03 12:45:42 CDT

Hi!
Yes, it is still valid. The error is still present.
An argument of type TQCString is passed to the tqDebug function.
The compiler cannot select a function with an argument of type TQString or an argument of type char.
That's why I suggested replacing the call to the tqDebug function in the widgets.cpp file with a call:
tqDebug (output, 0);

The second argument will be ignored, so the compiler will use the tqDebug variant with the type  argument char.
Otherwise, you will have to write another handler for the tqDebug function with an argument of type TQCString.

For the assembly, I simply removed the example “widgets” from the assembly list:
sed '/widgets \\/d' -i ${S}/examples/examples.pro

Comment 3 Michele Calgaro 2019-09-04 08:01:52 CDT

We will add functions which take TQCString arguments.

Comment 4 Michele Calgaro 2019-09-04 22:00:12 CDT

I was able to replicate the problem here. Commit 80dc1e531 added the new functions and solved the problem.

Can you please verify and confirm before I close the bug?

Comment 5 Michele Calgaro 2019-09-04 22:00:52 CDT

Note, the fix is only in tqt3. qt3 is no longer maintain for R14.1.x onwards.

Comment 6 Roman 2019-09-05 02:23:44 CDT

Now everything is fine, the error no longer pops up. 
For assembly I use overlay https://github.com/ormorph/TDE
There is no qt3 package in this overlay.
Deleted the line:
sed '/widgets \\/d' -i ${S}/examples/examples.pro

Now everything is going without errors.

Comment 7 Michele Calgaro 2019-09-09 20:59:54 CDT

Great, glad to know that and thanks for reporting the issue.
By the way, we encourage you to report bugs there, since TGW is now the place to go for development :-)
