for most options, configure provides reaonable defaults, given in brackets
For most options, configure provides reasonable defaults, given in brackets.
In particular, it is able to guess the right settings for shared library
creation and linking on some common systems. Likewise, it tries to find Python
in some standard directories if you don't specify a path explicitly.

For most options, configure provides reasonable defaults, given in
brackets. In particular, it is able to guess the right settings for
