With these it helps I was reading a book when I saw virtual void enter()=0; What does the asignment do while it is not a variable? , That code is not C#, it is C++, and is the equivalent to C#
code :
abstract class MapSite
    public abstract void Enter();

help you fix your problem You can't.
You should use a static function instead (not a static member function, but a free function).
code :
// IThread.h
class IThread
    void BeginThread();
    virtual void ThreadMain() = 0;

// IThread.cpp
extern "C"
    static void __cdecl IThreadBeginThreadHelper(void* userdata)
        IThread* ithread = reinterpret_cast< IThread* >(userdata);
void IThread::BeginThread()
    m_ThreadHandle = _beginthread(
                     m_StackSize, reinterpret_cast< void* >(this));

I wish did fix the issue. What version of the framework are you using? There is a targetplatform option you may need to set if you are using 4.0/4.5 for example.
error: argument of type ‘void* (Thread::)(void*)’ does not match ‘void* (*)(void*)’

it fixes the issue pthread_create is a C function, and knows nothing of C++ member functions. You'll need to give it a static or non-member function, and pass a pointer to your Thread object via the final argument of pthread_create; something like:
code :
class Thread
    virtual void* run(void *params) = 0;

    void start(void * params)
        this->params = params;
        pthread_create(&threadId, 0, &Thread::static_run, this);

    static void * static_run(void * void_this)
         Thread * thread_this = static_cast<Thread*>(void_this);
         return thread_this->run(thread_this->params);

    pthread_t threadId;
    void *params;
std::thread thread;

void start(void * params)
    thread = std::thread([this]{run(params);});

should help you out When compiling the C# dll, it is targeting a .NET version prior to framework 4.
Make sure the setting in the compiler is targeting the correct platform version.

will be helpful for those in need It is not JVM itself who invokes main method. This is rather a job of Java launcher, i.e. java.exe.
Java launcher is a small program written in C that uses regular JNI functions:
