I have followed James Key's instructions (https://wiki.wxPython.org/BuildWxPythonOnRaspberryPi, updated version, wxPython-4.0.7.post2, with GTK3) as closely as I can: I wanted to use the default python-3.7.3. All went well until "python3 build.py build bdist_wheel", where about two hours in on my Pi2B the 478/868 compile failed with a fatal error:
477/868] Compiling sip/cpp/sip_advwxTaskBarIconEvent.cpp
[478/868] Compiling sip/cpp/sip_advwxLayoutAlgorithm.cpp
collect2: fatal error: ld terminated with signal 9 [Killed]
compilation terminated.

Can anyone suggest a likely cause, please?
