"Out-of-tree-extensions" missing for Windows

[thohan88]

Hi,
Thanks for all the great work on maintaining this package. I can interpret from the work being done on 0.10.0 that this requires some effort, but it's greatly appreciated.

"Out-of-tree-extensions" appear to be missing on Windows as reported in other issues (e.g. #23). I made a quick script to check which extensions are not available based on duckdb_extensions() and came up with the following list for version 0.10.0 and 0.9.2. As pointed out by @Mause, most of these are "Out-of-tree-extensions".

0.10.0

Most of the extensions you've noted as "missing" are more accurately described as "out-of-tree extensions". The exceptions are the visualizer extension, which has been removed, and the jemalloc extension, which is only ever compiled in, you can't download it

Thank you. I figured that was a probable cause for the jemalloc and visualizer extensions. I was not familiar with the definition of "out-of-tree-extensions", but assumed that listed official extensions (e.g. azure, spatial) were intended to be supported by R similarly to Python. Reading up on duckdb/extension, I understand that the build process is more complex than that.

As a note, @Maxxen added spatial build for R in the duckdb/duckdb_spatial repository, it should be available from v0.10.0 onward.

What's the best way forward here? Who could help tick all the boxes?

[natbprice]

Is there a workaround to build/install extensions (e.g., azure) on Windows? Does the fix require opening an issue under the relevant extension?

[abfleishman]

I am also interested in the Azure extension. I do not understand what it takes to enable one of these extensions. Is there a PR that I can look at to see an example? (I am guessing it is way out of my wheelhouse but maybe it will help someone else get started?).

[abfleishman]

Any updates on this front? Any advice on how to get the Azure extension running in windows?
