make build EC GF2m simple method was not declared in this scope error in centos7

Question

When I compile the code I get an error telling me my 'EC_GROUP_set_curve_GF2m' function was not declared in this scope. 

from:github bubichain-v3

My Centos 7 is newly installed and installed software package:

sudo yum install -y automake autoconf libtool g++ libssl-dev cmake libbz2-dev python

Step 1: I assume that your present working directory is the Ruby source directory.

Step 2: Download the patch as shown below:

# wget https://bugs.ruby-lang.org/attachments/download/3707/out.patch

# ls out.patch
out.patch

# find . -name ossl_pkey_ec.c
./ext/openssl/ossl_pkey_ec.c

Step 4: Run the downloaded patch

# patch ./ext/openssl/ossl_pkey_ec.c < out.patch
patching file ./ext/openssl/ossl_pkey_ec.c
Hunk #1 succeeded at 757 (offset -5 lines).
Hunk #2 succeeded at 814 (offset -5 lines).
patching file ./ext/openssl/ossl_pkey_ec.c
Hunk #1 FAILED at 7.
1 out of 1 hunk FAILED -- saving rejects to file ./ext/openssl/ossl_pkey_ec.c.rej

This should work.
