Show the exact errors, not just your interpretation of them.

[shakthi]

pthread_create(&thread1,NULL,(void*)&even,NULL);

error:

• invalid conversion from void* to (void*)()(void)
• initalizing argument in pthread_create(....)

the above are errors in first level

What type has "even"?
Just seems you need:
@pthread_create(&thread1,NULL,(void *)even,NULL);@

[Franzk]

I think you need to pass in a function that accepts a void pointer:
@void even(void*);@

Even if you don't use the pointer, the function has to accept it to match the function type expected by pthread_create
@void *(start_routine)(void)@
as stated in the "pthread_create man page":http://linux.die.net/man/3/pthread_create. If that doesn't fix it, please provide a zipped project with your code or code that shows the exact issue you have, so we can try and debug ourselves.

Moved to the C++ Gurus forum, this has nothing to do with Qt.
