Can I load an SQLite extension in GRDB?

[stsandro]

I want to load an SQLite extension and then use it with raw SQL in GRDB. Is that possible, or am I ill-fated here?

Hello @stsandro, my Google search tells that the SQLite library shipped on Apple operating systems is not able to load extensions.

You can link GRDB with a custom SQLite build that is able to load extensions. This is uncharted territory, so please report the results of your investigations if you have time.

@groue @stsandro it is possible with a custom SQLite build, however the SQLiteLib project used to build SQLite actually mirrors the configuration of the onboard iOS SQLite that disables extension loading via -DSQLITE_OMIT_LOAD_EXTENSION flag passed during compilation line reference here.

The SQLiteLib project doesn't allow for removing of that flag as user provided configuration, so I've forked it to remove the flag and loading extensions works. I added an issue in that project asking about remove flags as user customization.

Thank you @michaelmedellin! Let's wait a little bit, until @swiftlyfalling can see your issue.

@groue @michaelmedellin Thank you both for the information provided. I'll have a closer look at everything when I get back from vacation.
