--- Comment #4 from Dominik Vogt <vogt at linux dot vnet.ibm.com> --- @comment 2 I can't see anything special that the file does: -- secp256.go -- package secp256k1 /* #cgo CFLAGS: -I./secp256k1 ... #include "./secp256k1/src/secp256k1.c" */ import "C" -- END -- Then in -- secp256k1.c -- const secp256k1_nonce_function_t secp256k1_nonce_function_rfc6979 = nonce_function_rfc6979; -- END -- Just this one occurence of the symbol "secp256k1_nonce_function_rfc6979".
