Building a shared libpython
|
||||
---------------------------
|
||||
|
||||
Starting with Python 2.3, the majority of the interpreter can be built
|
||||
into a shared library, which can then be used by the interpreter
|
||||
executable, and by applications embedding Python. To enable this feature,
|
||||
configure with --enable-shared.
