[issue35170] 3.7.1 compile failure on CentOS 6.10; _ctypes did not build

[Alexey Izbyshev]

Alexey Izbyshev <izbyshev at ispras.ru> added the comment:

The in-tree copy of libffi was removed in #27979 (between 3.6 and 3.7) for all platforms except Windows and macOS. Therefore, you need libffi development package installed in your system to build CPython 3.7. 

As for PIP, personally, I think that's an overkill to require ctypes, especially at CPython build time. If you don't want to build ctypes, I believe you may use '--without-ensurepip' configure option as a workaround.
