MAUI on iOS: DllNotFoundException #223

Open DamianAtIQVIA opened 3 hours ago

DamianAtIQVIA commented 3 hours ago

When I try to open a DB connection I get System.DllNotFoundException. It seems like there is no native libraries for iOS (and probably for Android too):

2024-10-23 09:09:26.123078+0200 DuckDbMauiIssue[39958:8162189] System.TypeInitializationException: The type initializer for 'DuckDB.NET.Data.DuckDBConnectionStringBuilder' threw an exception. ---> System.DllNotFoundException: duckdb at DuckDB.NET.Data.DuckDBConnectionStringBuilder..cctor() 2024-10-23 09:09:26.123281+0200 DuckDbMauiIssue[39958:8162189] --- End of inner exception stack trace --- at DuckDB.NET.Data.DuckDBConnection.get_ParsedConnection() at DuckDB.NET.Data.DuckDBConnection.Open() at System.Data.Common.DbConnection.OpenAsync(CancellationToken cancellationToken) 2024-10-23 09:09:26.123495+0200 DuckDbMauiIssue[39958:8162189] --- End of stack trace from previous location --- at DuckDbMauiIssue.MainPage.OnCounterClicked(Object sender, EventArgs e) in /Users/.../Projects/temp/DuckDbMauiIssue/MainPage.xaml.cs:line 17

You can reproduce the issue running this project: https://github.com/DamianAtIQVIA/DuckDbMauiIssue

Can you try including libduckdb.dylib from libduckdb-osx-universal.zip to see if that works?
