Elliptic curve point multiplication with libgcrypt

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?

Installation of 2.2

Hi, I'd like to upgrade to version 2.2.3  Will it be sufficient do download just the tarball on the downloadpage and build that? Afterwards I can delete the previous versions? If I do that, will the conf. file be deleted? Thank you. Jurgen. ___
