Why does Stratus HLS report this error?

I'm trying to implement a module that reads and writes a memory. The memory is instantiated in the top module and passed down to submodules.

It seems there are errors in the generated memory header file.

I'm using Stratus 19.1 on CentOS 7. I've tried synthesizing "Lab 3: Explicit Memorys" (which comes with Stratus) and it was completed without errors.

Can anyone tell me what the cause of this error and how to solve it?

Also, the way I instantiate memories is same as in Lab3.

I'd prefer to keep ports of memories the same because in the project I'm working on, one module only writes to a memory block and another module only reads from this memory. They will access the same memory simultaneously so I'd rather not to use a shared interface.

Here's the setting of the memory:

And Here's my code:

sc_out< sc_uint<8> > dout;

sc_in < bool > rst;

sc_signal< bool > sgn;

//sc_uint<8> mem[256];

writer_wrapper m_writer;
