Hi @sevgicorumlu and thanks for posting here :)

From the errors, it seems you are only compiling ecdh_example.c.

All the functions missing reside in ecdh.c. You need to also compile + link that file in the build.

This is a common error for less experienced developers. See similar issues in my AES project: https://github.com/kokke/tiny-AES-c/issues/107 https://github.com/kokke/tiny-AES-c/issues/79 https://github.com/kokke/tiny-AES-c/issues/71

Closing since this is a user-error, not including a file in the build.
