Mono中的DLL配置

Question

我正在尝试获取Svn.NET（ http://www.pumacode.org/projects/svndotnet/ ）库，以便在我的Mono项目中使用。 我尝试编译它的ockapp-> svnmockapp项目（ http://www.pumacode.org/projects/svndotnet/browser/trunk/SvnMockApp ），我能够正确地引用并正确地进行编译。

我了解它引用了另外两个模块libapr（libapr-1.so.0）和svn_client（libsvn_client-1.so.0），通过它们我在/ bin / Debug中创建了PumaCode.SvnDotNet.dll.config。

这就是我为尝试使模拟应用程序至少输出某些东西以表明它确实与SVN接口所做的所有尝试。 但是，它不起作用。

输入的不与SVN接口的命令可以正常工作：

$ mono SvnTest.exe -usage
Usage: SvnTest <subcommand> [options]
Short Options: ~?.V
Subcommands: add, checkout[co], status[st], update[up]
For help on subcommands, use the -?/--help subcommand option.

尝试访问SVN的命令将引发异常：

$ mono SvnTest.exe st
An exception was thrown by the type initializer for PumaCode.SvnDotNet.AprSharp.Apr

Unhandled Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object

  at PumaCode.SvnDotNet.SubversionSharp.SvnMockApp.Application.Main (System.String[] args) [0x00000]

使用MONO_DEBUG_LEVEL =“ debug”，我们将以下日志粘贴到此处 。

在日志的末尾，我们看到了以下内容：

.

我尝试在SvnTest.exe存在的目录中对适当的模块进行符号链接，但这仍然存在。

我怎样才能解决这个问题？

我是否将PumaCode.SvnDotNet.dll.config放在错误的文件夹中？ （我将其放在/ bin / Debug并尝试了/ bin）

我该怎么办才能补救？

感谢您的热心帮助！ 非常感激！

这是配置文件：

（PumaCode.SvnDotNet.dll.config）

<configuration>
     <dllmap dll="libapr" target="/usr/lib/libapr-1.so.0"/>
     <dllmap dll="svn_client-1" target="/usr/lib/libsvn_client-1.so.0"/>
</configuration>

Answer 1

您的配置文件没有正确的dll参考。 在日志中，Mono尝试加载libapr-1库，但是您的配置文件只有libapr项。 我认为正确的映射应该是：

<configuration>
    <dllmap dll="libapr-1" target="/usr/lib/libapr-1.so.0"/>
    <dllmap dll="svn_client-1" target="/usr/lib/libsvn_client-1.so.0"/>
</configuration>

Answer 2

通过将dllmap手动添加到/ etc / mono / config来解决它，这不是最好的方法，但至少可以正常工作。
