C++ ptr_fun not finding void parametered functions -

i tried using std::ptr_fun wrap function, when try wrap function void parameter , bool return type end error:

code:

std::function<bool()> cr = std::not1(std::ptr_fun(&funct1));

function:

bool funct1()       {                       return false;      }

the error:

 error: no matching function call 'ptr_fun(bool (*)())'

but whenever change parameter int, problem seems go away.

how wrap function void parameter???

not 100% sure, try using void* parameter
