expected primary-expression before ',' token

Question

Im currently getting the error:

kernel.c++:76:21: error: expected primary-expression before ',' token
     Task task1(&gdt , taskA);
                     ^
kernel.c++:77:21: error: expected primary-expression before ',' token
     Task task2(&gdt , taskB);

Not sure why this is happening here is the code of my kernel.c++ simplified:

void taskA();
void taskB();

extern "C" void kernelMain
        (
            /*arguments...*/
        )


{
       gdt gt;

       TaskManager taskManager;
       Task task1(&gdt , taskA);
       Task task2(&gdt , taskB);
       taskManager.AddTask(&task1);
       taskManager.AddTask(&task2);
}

void taskA()
{
    while(true)
        printf("A");
}


void taskB()
{
    while(true)
        printf("B");
}

If you want to see my actual kernel code : https://github.com/amanuel2/OS_Mirror/blob/master/kernel.c%2B%2B .. Any Help

Here is my task.h simplified:

class Task
{
          friend class TaskManager;
              private:
                  uint8_t stack[4096]; // 4 KiB
                  CPUState* cpustate;
              public:


              Task(gdt *GlobalDescriptorTable, void entrypoint());
              ~Task();
    };


    class TaskManager
    {
            private:
                Task* tasks[256];
                uint32_t num_task;
                uint32_t current_task;
            public:
                TaskManager();
                ~TaskManager();
                bool AddTask(Task* task);
                CPUState* Schedule(CPUState* cpustate);
    };

If you want to see whole code for task.h here it is : https://github.com/amanuel2/OS_Mirror/blob/master/task.h ..

and finally minimized task.c++:

Task::Task(gdt *GlobalDescriptorTable, void entrypoint())
{
 /*Stuff Happenes Here.. But i Minimized it*/
}

If you want to see the actual task.c++ here it is : https://github.com/amanuel2/OS_Mirror/blob/master/task.c%2B%2B .. I dont understand why i get that error. Any Help Would be greatly appreciated thankyou.

Answer 1

Your error is probably in these two lines:

Task task1(&gdt , taskA);
Task task2(&gdt , taskB);

It should be

Task task1(&gt , taskA);
Task task2(&gt , taskB);

You should change your type names and variable names so they don't look alike that much so as to avoid these kind of errors.
