c# - 无论我做什么，Mono dllnotfound

Question

我希望你能帮助我。我在我的 ubuntu 系统上安装了单声道，但是当我尝试启动一个应用程序时，我得到一个 dllnotfound 异常。缺少的 Dll 是 libgdiplus。我尝试将/usr/lib/添加到共享库，并尝试将 Dll 添加到单声道配置文件。两者都不起作用，但我的系统可以找到 .so 文件，当我查找它时，甚至 ldconfig 也说它在那里:

sudo ldconfig -p |grep libgdiplus
    libgdiplus.so.0 (libc6) => /usr/lib/libgdiplus.so.0
    libgdiplus.so (libc6) => /usr/lib/libgdiplus.so

但是我在尝试启动单声道时得到的错误仍然是一样的。但是当我试图将这个库的路径添加到 LD_LIBRARY_PATH 环境变量时我感到非常好奇，因为当我尝试时，我发现这个变量不存在并且当我将它设置为/usr/lib mono 时并不关心并给我相同的错误信息

这是我尝试运行 Mono 时得到的控制台输出:

我的问题现在已经解决了。经过数小时的尝试让单声道识别 libgdiplus 的路径后，我刚刚重新安装了该库。现在这个异常不再发生(虽然另一个是...:( )
