How to add MPC as a member in a class?

[C1009919253]

For example, I want to add MPC's object mpc_t in class A, but I can't initialize mpc_t in A's constructor function.
How could I fix that problem?

I would guess the problem here is the lack of a default constructor of the MPC class.

What you can do to fix that is for example have a shared_ptr as your member class and dynamically define it in the constructor.
Another option can be to call the MPC constructor in the initializer list as suggested in https://stackoverflow.com/questions/12328150/class-member-without-a-default-constructor

Thanks for your help, I tested the first way, and it worked!
