有
我有一个由VC开发的C ++应用程序，编译为DLL文件。 （该DLL是访问物理电池）。我还有C＃测试控制台应用程序，称为DLL文件，以获取电池参数。
它们都在Windows上顺利运行，但是当我尝试通过单声道在Ubuntu上运行它时。 首次使用mono运行时总会出现异常，并且只在第一次显示时出现。 没有在第二，第三......时间显示。
命令如下：
root @ ubuntu：/ home / user1 / Desktop / CSharpTestConsoleAppFolder #monmon ConsoleApplication1.exe
如下例外：
mono: pthread_mutex_lock.c:312: __pthread_mutex_lock_full: Assertion `(- (e)) != 3 || !robust' failed.

=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================
附加信息：如果我先运行“gdb mono”，然后运行测试控制台应用程序，则没有异常。似乎在异常消息中或运行“gdb mono”之后有消息“Mono Support Loaded”。
答案 0 :(得分：0)
虽然mono是跨平台的，但C ++却不是。您将不得不使用GCC或类似的编译器在Linux上重新编译您的DLL。此外，如何从单声道代码引用DLL也很重要。我建议使用PInvoke来避免路径等任何复杂情况。
答案 1 :(得分：0)
您可能意味着托管C ++，这就是您的应用程序实际工作的原因。可能只是你（或单声道运行时）试图释放一个未初始化的指针，可能会在以后初始化 - 或者在另一个线程上，因为你的堆栈跟踪表明有许多线程正在运行（其中一个线程似乎卡在了ioctl上） （））。
