Elliptic curve operations problem using libgcrypt

[Hassan Mostafa]

I am a new user of libgcrypt. I am trying to do math operations on elliptic
curves for example scalar multiplication. I am started with writing a code
which simply initialize the library then generate a context for EC
operation and the get the private key and display it. in my code.

1. I am trying to get the private key value in variable called x but it
gives an error.
2. then display this x.

please I need help in this urgently.
