You will have to install the Python development libraries on your system (sudoku apt-get , and/or use the CMake configuration option -DPYTHON_INCLUDE_DIR to point to the folder containing it.
Lucky you, it is also a highly Google-able error: "missing Python.h" should help you out!
Best regards

Dear Alberto,
the old releases are still available https://github.com/nest/nest-simulator/releases on GitHub. This includes v2.20.1 https://github.com/nest/nest-simulator/releases/tag/v2.20.1, which I would recommend over 2.20.0, as it contains a fix for #1394 https://github.com/nest/nest-simulator/issues/1394, which could lead to wrong simulation results under certain circumstances.
Cheers, Jochen!

Dear experts,
I'd like to install the Nest version 2.20.0 instead of the last 3.1.
Is it still available for download?
Thanks Alberto
