Hi,

I build NHibernate 0.8.3 successfully. However, when I try to test NHibernate I get a 'build failed' message. I call the build file with these params:

NAnt -D:project.config=release -D:nhibernate.dialect="NHibernate.Dialect.PostgreSQLDialect" -D:nhibernate.connection.driver_class="NHibernate.Driver.NpgsqlDriver" -D:nhibernate.connection.connection_string="Server=localhost;initial catalog=nhibernate;User ID=postgres;Password=xxxxxx;Encoding=UNICODE;Min Pool Size=2" test >output-release-test.log

I am using PostgreSQL 8.0.1. The database is up and running.

Here is an extract of output-release-test.log:

I have no idea, why a connection cannot be established. Any help is highly appreciated. Thank you.

Well, it says in the exception message that it can't find Npgsql.dll. Do you have it in the GAC or in some accessible place (in the same directory as the NHibernate.Tests.dll for example)? You also have to copy Mono.Security.Tls.dll.

I missed Mono.Security.Tls.dll. That did the trick. Thx.

I'm getting the exact same error message but with MySql. I've registered MySql.Data.dll in the GAC, and I don't suppose I need Mono.Security.dll do I?

The IDbCommand and IDbConnection implementation in the assembly MySql.Data could not be found. Please ensure that the assembly MySql.Data is in the Global Assembly Cache or in a location that NHibernate can use System.Type.GetType(string) to load the types from.

I've tried using MySql.Data without NHibernate and it works fine. I've also noted that in the source code for the Connection provider it mentions that this namespace requires ICSharpCode.SharpZipLib.dll which I have also added to the GAC.
