Using Guile 2.2 modules with Guile 3

Using Guile 2.2 modules with Guile 3

[Olivier Dion via General Guile related discussions]

Hi,

Say I want to use guile-dbi wich use Guile 2.2.  Is there any danger for
me to use it with Guile 3.0?  I see that Guile will recompile the module
because the already compiled one does not match, I guess.  Other than
that, any side effects?

Regards,
old

Going by the package definition, guile-dbd-postgresql seems to make a 
Guile extension (C). There have been incompatible changes (both on the 
Guile code level, and presumably on the C level). As such, sounds risky 
to me.

Also, for whatever reason, guile-dbi propagates an old guile, so you'll 
get a propagation conflict without guarantees on which Guile version ‘wins’.

Greetings,
Maxime.

So I guess it would be better for me to use something like guile-sqlite3.

Myself I think it would be better to update guile-dbi to the new Guile.

There were a few incompatible changes between the two Guile major 
versions, but very little and easy to resolve in my experience.
