ubuntu - 如何使用 dllimport 解决 DllNotFoundException？ (单声道)

Question

我是 Unix/Linux/Ubuntu 的新手。

我正在将 Mono 与 VB 一起使用，我正在尝试通过 DllImport (CliSiTef32I.dll/libclisitef.so) 使用库中的方法，但是它一直给我 DllNotFoundException

在论坛中搜索我已经尝试了一些事情:

ld.so.conf 包含库的路径

project.exe.config中的dllMap

任何帮助表示赞赏。

我的代码:(我尝试直接使用 .Dll 和 .SO 导入，但均无效)

C#

using System;
using System.Runtime.InteropServices;

namespace SitefCSharp

{

static class MdlTEF

{

[DllImport("CliSiTef32I.dll")] // [DllImport("libclisitef.so")]    
private static extern int ConfiguraIntSiTefInterativo(string EndSitef, string IdLoja, string IdTerminal, Int16 Reservado);

        static void Main()
        {
            int sts = 0;
            try
            {
                sts = ConfiguraIntSiTefInterativo("", "", "", 0);                
            }
            catch (Exception ex)
            {
                string msg = ex.ToString();
                //the exception is System.DllNotFoundException at (wrapper managed-to-native)
            }
        }
    }
}

VB

Imports System
Imports System.IO
Imports System.Windows.Forms
Imports Microsoft.VisualBasic.Interaction


Public Module EmptyClass

    Public Sub Main()
    Dim sts as Integer
    Try
        sts = ConfiguraIntSiTefInterativo("", "", "", 0)
    Catch ex as Exception
        MsgBox(ex.ToString)
    End Try

    End Sub

    Public Declare Function ConfiguraIntSiTefInterativo Lib "libclisitef.so" (ByVal EndSiTef As String, ByVal IdLoja As String, ByVal IdTerminal As String, ByVal Reservado As Int16) As Int32
    'Public Declare Function ConfiguraIntSiTefInterativo Lib "CliSiTef32I.dll" (ByVal EndSiTef As String, ByVal IdLoja As String, ByVal IdTerminal As String, ByVal Reservado As Int16) As Int32

End Module

//project.exe.config文件中的dll映射

<configuration>
    <dllmap dll="CliSiTef32I.dll" target="libclisitef.so"/>
</configuration>

//我的 ld.so.conf 文件...我尝试将库放在所有这些路径中

/home/pdv/Projetos/PDV/kaiser/clisitef
/lib
/lib64
/usr/lib
/usr/lib64
/usr/local/lib
/usr/local/lib64
/home/pdv/Projects/TesteTef/TesteTef/bin/Debug
include /etc/ld.so.conf.d/*.conf

我使用 mono log_level=debug 发现了问题
它无法加载 32 位 dll，我尝试了 64 版本，它工作!
