Hi gpg hackers!

I want to implement an elliptic curve point multiplication (Q=dG) operation
with libgcrypt. I attach my code but my program doesn't work and it has
many errors. I comment the workflow of my program in the attached code.
my question is how do you implement Q=dG in C with libgcrypt? any idea
about my mistakes and how should I fix them?
