Hi Duncan,

it looks like the developers have added the implementation of std::hash in 5.13 and we do not need anymore the content of include/nodes/internal/QStringStdHash.hpp

See commit https://code.qt.io/cgit/qt/qtbase.git/commit/?id=4469e36d7203a55a4e158a50f0e9effc3f2fa3c2

I have Qt 5.13 on my machine as well and strangely can't reproduce your issue.

Temporarily you could comment out the content of QStringStdHash.hpp to proceed with your work. I'll see what could be done.

Thanks

Dmitry

Ok, it seems that the change made it to 5.14

@paceholder Hi there, I believe that is now functioning on my end. It successfully installed when I comment out the content of that file.

Additionally, I'm not sure if I'm going about compiling the examples the wrong way:

1. navigate to example directory
2. cmake CMakeLists.txt
3. make then gives me an error:

[ 12%] Building CXX object CMakeFiles/calculator.dir/Converters.o In file included from /usr/local/include/nodes/NodeDataModel:1, from /home/duncan/github/external/nodeeditor/examples/calculator/DecimalData.hpp:3, from /home/duncan/github/external/nodeeditor/examples/calculator/Converters.hpp:3, from /home/duncan/github/external/nodeeditor/examples/calculator/Converters.cpp:1: /usr/local/include/nodes/internal/NodeDataModel.hpp:4:10: fatal error: QtWidgets/QWidget: No such file or directory 4 | #include <QtWidgets/QWidget> | ^~~~~~~~~~~~~~~~~~~ compilation terminated. make[2]: *** [CMakeFiles/calculator.dir/build.make:76: CMakeFiles/calculator.dir/Converters.o] Error 1 make[1]: *** [CMakeFiles/Makefile2:76: CMakeFiles/calculator.dir/all] Error 2 make: *** [Makefile:84: all] Error 2

I'm probably missing something as I'm not incredibly familiar with this build process. Perhaps there's something I need to export or I am compiling them incorrectly?

Typically I do this:

> cd nodeeditor
> mkdir build
> cd build
> cmake ..
> make -j

Afterwards all the examples are located in nodeeditor/build/bin

[paceholder@xps13 build]$ ls bin
calculator  connection_colors  example2  images  styles  test_nodes

Ah, yes. They were already compiled. Everything looks good, I'll play around with it further and see what comes of it all! Thanks again.

I don't know if you'd like me to close this issue now since I "solved" it by commenting out that file, but I am happy to.

I removed, recloned, and followed the README and it all functioned as expected. Thanks again!
