Although you mention running the server on the Pi, I think it is worth
pointing out that you can run VAST itself on a Pi.
We have run other versions of VAST on a Raspberry Pi, so do expect VAST 12
to work there as well.

Mariano Martinez Peck has demonstrated running a GBS application on a Pi
that interfaces with a temperature sensor and records readings in a
GemStone database..

This is incorrect. The DLLs are independent of the client (Smalltalk or
other application).

GBS for VAST only supports the 32-bit library.
Unfortunately, adding 64-bit support is a huge engineering effort.

Recent *nix versions have made using 32-bit applications much more
challenging than in the past.

I just looked at the 3.6.8 distribution and both the bin and bin32
directories include msvcr100.dll.


If you want to interface directly to the GCI library, refer to the
GemBuilder for C documentation. An application that only retrieves string
responses is quite easily created. Replicating complex objects is much more
complicated, of course.
James Foster (https://github.com/jgfoster) has a number of projects on
GitHub, some of which could be used as a starting point for such an
interface.
