Building Python 3.7 from source runs into following error:

Answer 1

Edit setup.py

Find the following lines:

        system_lib_dirs = ['/lib64', '/usr/lib64', '/lib', '/usr/lib']
    system_include_dirs = ['/usr/include']

...and place each folder at the beginning of its respective list.

In my case I had to add: /usr/local/lib and /usr/local/include:

        system_lib_dirs = ['/usr/local/lib', '/lib64', '/usr/lib64', '/lib', '/usr/lib']
    system_include_dirs = ['/usr/local/include', '/usr/include']

Finally: make distclean && ./configure

You may want to ensure that export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH (or what have you) is added to the very end of /etc/profile and reboot, as well.
