在macOS上嵌入.NET内核的Firebird

我正试图让Firebird嵌入到一个简单的.NET核心（2.1）控制台应用程序场景中

我的项目文件如下所示：

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="FirebirdSql.Data.FirebirdClient" Version="6.4.0" />
  </ItemGroup>

</Project>

using System;
using System.IO;
using FirebirdSql.Data.FirebirdClient;

namespace Playground
{
    class Program
    {
        static void Main(string[] args)
        {
            var workingDir = Directory.GetCurrentDirectory();
            var dbPath = Path.Combine(workingDir, "Database.fdb");

            var connString = 
                new FbConnectionStringBuilder
                {
                    ClientLibrary = "libfbclient.dylib",
                    ServerType = FbServerType.Embedded,
                    UserID = "sysdba",
                    Database = dbPath
                }
                .ToString();

            Console.WriteLine(connString);

            FbConnection.CreateDatabase(connString, false);

            var sql =
                @"
                CREATE TABLE my_table (
                    id int NOT NULL PRIMARY KEY,
                    name varchar(20) NOT NULL
                );
                ";

            using (var conn = new FbConnection(connString))
            using (var cmd = new FbCommand(sql, conn))
            {
                conn.Open();
                cmd.ExecuteNonQuery();
            }
        }
    }
}

构建项目后（仅通过

dotnet build

），我将以下文件从Mac二进制软件包（

Firebird-3.0.4-33054-lipo-x86_64.pkg

）复制到输出目录（

/bin/Debug/netcoreapp2.1

）：

运行应用程序（

dotnet MyApp.dll

）时，我遇到一个异常：

Unhandled Exception: FirebirdSql.Data.FirebirdClient.FbException: Unable to complete network request to host "localhost".

在过去的15年里，我已经在许多场景（网络服务器、嵌入式）和不同的技术（Delphi、.NET、.NET核心）中成功地使用了Firebird，尽管只是在Windows上

---

有没有人能帮助解决这个问题，或者给我指出一个相关的地方，在那里我可以RTFM并自己解决这个问题？

你想在哪个版本的MacOS上运行这个问题？@EdMendez 10.13.6（High Sierra）我在这个问题上取得了一些进展：显然，由于库路径，嵌入式引擎未加载，正在尝试连接到

localhost

。修补

dylib

s没有帮助。在安装Firebird（它已将LIB放在预期的位置）并授予

/tmp/Firebird

目录的权限后，它工作了，但这远远不是我想要实现的无摩擦和孤立的部署场景（在windows上是可能的）。
