Linux C: Reference to non-static member function must be called

Question

I receive error:Reference to non-static member function must be called trying to build the following code:

HTTPClient::HTTPClient(int id,HttpListener& message) {
    pthread_t thId;
    pthread_create(&thId, NULL, processor, this);  <--error is here
}

void* HTTPClient::processor(void* userData) {
    HTTPClient* client = static_cast<HTTPClient*>(userData);
    client->run();
}

void HTTPClient::run() {
    while(true) {
        pthread_mutex_lock(&mMutex);
        pthread_cond_wait(&mCond,&mMutex);
        httpLoadFile(mUrl, mPath);
        pthread_mutex_unlock(&mMutex);
    }
}

I have found some methods trying to solve the error, but failed!

它说你不能将指向方法的指针传递给pthread_create ，你应该传递指向普通函数的指针。
