Question

我正在尝试使用Svn.NET（http://www.pumacode.org/projects/svndotnet/）库来在我的Mono项目中使用。我尝试编译它的mockapp - ＆gt; svnmockapp项目（http://www.pumacode.org/projects/svndotnet/browser/trunk/SvnMockApp），我能够正确获取引用并将其编译正确。

我知道它引用了另外两个模块libapr（libapr-1.so.0）和svn_client（libsvn_client-1.so.0），我在/ bin /中创建了PumaCode.SvnDotNet.dll.config调试。

这就是我所做的一切，试图让mockapp至少输出一些东西来证明它确实是SVN的接口。然而，它不起作用。

输入的不与SVN接口的命令正常工作：

$ 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的命令会引发异常：

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

使用MONO_DEBUG_LEVEL =“debug”，我们得到以下日志粘贴here。

在日志的尾端，我们看到了：

我已经尝试将SvnTest.exe所在目录中的相应模块符号链接，但这仍然存在。

我该如何解决这个问题？

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

我该怎么做才能解决这个问题？

感谢您的帮助！非常感谢！

继承配置文件：

（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引用。在日志中，Mono尝试加载libapr-1库，但您的配置文件只有libapr的条目。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

通过手动将dllmap添加到/ etc / mono / config解决它，而不是最好的方法，但至少它起作用。
