I'm trying to build Python 3.7.4 (as a non-root user on an older machine - SLES 11). After ./configureing and makeing, I get the following message:

Failed to build these modules:
_bz2                  _ctypes               _curses_panel

I'm most interested in _cytpes, since lacking that one gives me trouble later.

What do I need to do, or to have installed, for the building of the _ctypes module succeeds? Note that I don't have root privileges.

See https://bugs.python.org/issue31652 . You need to install libffi-dev or libffi-devel, and if the library is not in your library search path, add an appropriate LDFLAGS arg to ./configure . – Mark Plotnick Feb 09 '20 at 12:35
@MarkPlotnick: `LDFLAGS=-L/path/to/dir/with/ffilibs/` ? – einpoklum Feb 09 '20 at 12:43
Yes. The user who posted that used both -L and -R options. – Mark Plotnick Feb 09 '20 at 13:43
