I am trying to use secp256k1 for a toy project that I am working on for learning purposes. I am using Ubuntu 20.04 and I can clone and compile the library just fine. I have tried to include it in a simple hello world c file and I get the following error:
secp256k1/src/num.h:19:2: error: #error "Please select num implementation" 19 | #error "Please select num implementation"
I have tried googling this but I can't seem to find anything (only https://github.com/breadwallet/breadwallet-ios/issues/60 but not sure how it applies to my situation). All I did was use this line
#include "src/secp256k1.c" in my toy C code. I can't seem to find any documentation or walkthrough guide on simple usage of the library such as generating private keys and addresses (besides
secp256k1.h). Any help would be appreciated!
