error: unrecognized debug output level ‘nuplot_qt’

I still can't get it to function... looked through the src/qtterminal/embed_example file.cpp, but the problem lies in not knowing how to use those classes—QtGnuplotWidget and QtGnuplotInstance—from a different QT programme. Any assistance would be greatly valued.

Work on any project requires effort but the consistent effort is above all.
Get ready and know your domain.
Have a read.

Cpp isn't required to exist as a without delay executable program. The accurate manner to run the preprocessing step on its very own, on any POSIX tablet device, has been "cc -E" for just about all the time, that's what autoconf simply tries first.

I am unable to make the shared library. after manually patching the files mentioned in https://sourceforge.net/p/gnuplot/patches/649/
./prepare doesnt seem to work. following with the procedure, resulted in executable files rather than a shared library

Thanks for the reply. I will try it soon.

still unable to make it work... had a look in to src/qtterminal/embed_example.cpp but the issue is how to access those classes namely QtGnuplotWidget and QtGnuplotInstance from another QT application. any help would be highly appreciated.

Well I am trying to create an interactive plot inside a QT application. some thing like in GNU Octave. my idea was to link gnuplot to the program and use QT to add QtGnuplotWidget as a widget to my application and control the plot using QtGnuplotInstance

widget_ = new QtGnuplotWidget(this);
instance_ = new QtGnuplotInstance();
instance_->setWidget(widget_);
widget_->show();
widget_->resize(600, 600);
*instance_ << "plot(sin(x))";

I am trying to link gnuplot_qt as a shared library to one of my projects in Qt5. however the attempt is failing with the following error:
g++ -Wl,-O1 -Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now -o visualization main.o MainWindow.o moc_MainWindow.o -gnuplot_qt -gnuplot_x11 -lQt5Widgets -lQt5Gui -lQt5Core -lGL -lpthread
g++: error: unrecognized debug output level ‘nuplot_qt’

A shared library of gnuplot was created from source using the following commands
./configure --with-qt=lib
make

how to fix this ?
