qtvcp python3 in master was created by cmorley
I have pushed work in master so qtvcp can be used with python 2 or 3 now.
here is some detail how to compile for testing: github.com/LinuxCNC/linuxcnc/issues/820
tested on buster with python3 (you'll need to install python3 versions of libraries for pyqt/qtvcp)
buildbot currently does not build python3 binaries.
Anyone with custom screen handler files may need to do some minor changes.
please report any difficulties - thanks
Chris

I want to try out pi3d in a qtvcp environment but pi3d only works with python3. How do I install python3 libraries for qtvcp?

This works for buster:
./configure --with-python=python3 --with-boost-python=boost_python3-py37
make clean
make -j2
make clean is important.
The libboost version is found in /usr/lib/x86_64-linux-gnu/libboost_python-pyXX.so
after you get linuxcnc compiled with python3, all the python3 libraries that qpyqt/qtvcp requires need to be pulled in, which is basically changing to python3-pyqt5:
python3-pyqt5-qtopengl
etc. Qtvcp is pretty good about telling you in the terminal what the missing library is called.
For designer you don't need or want the precompiled library that we supplied in linuxcnc (libpyqt5_py2.so), just use the stock one that should be supplied when you bring in designer. Still need to link to qtvcp plugins though.

Did you run make clean before make?
Bit of discussion here, but not related to tkinter.

But the error is not from run of make!
The error happens during run of configure

Did you solve it? I have same problem.
Edit: The problem was between the chair and the keyboard. I forgot to do dpkg-checkbuilddeps.
