can vector push_back be used for user define classes

[Greatrebel]

Hi all,

I am trying to use vector iteration to access the member function of a variable length array, the codes as following:

vector<slave_cpu> slave_array;

for (i = 0; i < n_slave; i++)
{
slave_cpu slave;
slave_array.push_back(slave);
}
for (i = 0; i < slave_array.size(); i++)
{
router.r_port( slave_array[i].target_port );
}
n_slave is from command line argument. When I compile it, I got some error like
./src/main.cpp:140: instantiated from here
/usr/local/systemc-2.2/include/sysc/communication/sc_interface.h:84: error: ‘sc_core::sc_interface::sc_interface(const sc_core::sc_interface&)’ is private
./src/slave_cpu.h:28: error: within this context

main.cpp:140 is slave_array.push_back(slave); from the error, it seems like the function access to the private member of slave, I thought the push back should put pointer things to the vector, it should not touch this private member.

Anyone has any idea about the error?

Thanks in anticipation
