Hi team,

Recently I have been asked to specify if the python dependencies interacts on each python execution or if they are used just at the time of the installation of python.

• gdbm (GPL-2.0)                                            python3 prerequisites
• gettext (LGPL-2.1)                                        python3 prerequisites
• libgdbm.a(libgdbm.so.6) (GPL-3.0)         python3 prerequisites
• xz-libs (GPL-2.0)                                           python3 prerequisites
• libgmp.a(libgmp.so.10) (GPL-3.0)           python3 prerequisites

The objective is to determine in what ways does the IBM product/XaaS offering interact, directly or indirectly via dependencies, with the GPL, AGPL or LGPL code?

As far as I understand python itself and the different libraries use those packages at the installation time, what I'm not sure is if they are being used at the execution time ( every time we call python ).

What I'm looking is to determine the type of interaction between the dependencies and the packages itself.

Type of interactions:

Static Linking.

Dynamic Linking.

Scripting Language.

Command Line Invocation.

Pipes or Sockets.

Standard local API call.

Remote API call.

Non-Standard API call.

Combining code.

Other interaction.

Thanks in advance.

gettext (libintl.a) is the only direct dynamic linking from libpython3.  gdbm, xz-libs and other libraries are utilised by specific python3 standard modules (/opt/freeware/lib64/python3.9/lib-dynload)  through dynamic linking.  So it depends on the usage if only python3 is used or the standard modules are also imported and used.
