Does't support SQLite at Linux ARM64

[index1207]

Environment:

OS: Ubuntu 22.04 (QEMU)
Arch: ARM64
.NET SDK version: 8.0

Build

I had build at x86_64 Windows Machine by below command line.

dotnet publish -c Release -r linux-arm64

Libraries

Example Code:

public T QuerySomething<T>(string sql, object param)
{
    return dbConnection.Query<T>(sql, param);
}
...
SqlMapper.AddTypeHandler(new CustomTypeHandler()); // Implemented all interface.
...
QuerySomething<Model>("SELECT * FROM Model WHERE CustomTypeValue=@CustomTypeValue", new { CustomTypeValue = customTypeValue }

System.Data.SQLite.Core

I already installed libsqlite3-dev package. but it requires SQLite.Interop.dll.

Exception:
Unable to load shared library 'SQLite.Interop.dll' or one of its dependencies. In order to help diagnose loading problems, consider using a tool like strace. If you're using glibc, consider setting the LD_DEBUG environment variable:

System.Data.SQLite.Core with x64 Linux/Windows

No Exceptions.

Microsoft.Data.Sqlite.Core

Exception:
No mapping exists from object type CustomType to a known managed provider native type.

Doesn't work SqlMapper.AddTypeHandler().

Is there a way recommended usage in Linux ARM64?

Anything related to the mysql client not working is a question for the mysql client; in particular anything to do with

Unable to load shared library 'SQLite.Interop.dll' or one of its dependencies.

^^^ is nothing to do with Dapper, and I can't offer guidance.

For the other question here:

No mapping exists from object type CustomType to a known managed provider native type.

I'd need to see a runnable example / repro that I can investigate.

Here is the repro code:

// ERROR:
static IEnumerable<dynamic> QueryObj<T>(IDbConnection dbConn, string sql, object obj)
{
    return dbConn.Query(sql, new { Value = obj });
}
QueryObj(dbConn, "SELECT * ...", obj);

// SUCCESS:
static IEnumerable<dynamic> QueryObj<T>(IDbConnection dbConn, string sql, object obj)
{
    return dbConn.Query(sql, obj);
}
QueryObj(dbConn, "SELECT * ...", new { Value = obj});

The error No mapping exists from object type ... occurs only Microsoft.Data.Sqlite package.
It works fine in System.Data.SQLite package.

I need to see exactly what you're seeing. The type and value of obj here is unclear, and it really, really matters. This is not a runnable repro. Please show a complete, minimal example that I can use to investigate this.

Also, no <T> is shown, so that won't compile, and the iterator is not iterated, so it won't even do anything.
