Not able to build rpm from src - centos

Question

I need to rebuild rabbitmq-server-3.1.5 with my changes to some of the static files.
But before doing that I thought of being sure if I can rebuild the rpm without my changes first, and struck with the below issue.
I just installed the source-rpm and edited the SPEC file and changed the version to next minor number, and run the command
rpmbuild -ba rabbitmq-server.spec
Below is the SPEC file,
%define debug_package %{nil}

whereas I didn't face this issue while performing these steps on the other higher version of Rabbitmq-server, and I successfully rebuilt the rpms too. I've no clue why this is happening and also I'm very new to these kind of builds.
would need some expert advice to solve this issue.

Answer 1

This is the important line in the error output:
src/dtree.erl:44: type gb_tree() undefined
In Erlang/OTP 17.0, the type gb_tree() was deprecated, and the type gb_trees:tree() was introduced to replace it. gb_tree() was finally removed in Erlang/OTP 18.0.
RabbitMQ 3.4.0 changed the type spec to use the newer type, and it is thus the earliest RabbitMQ version that can be built with Erlang/OTP 18. Here's the commit where the change was made.
To solve this problem, either use a newer version of RabbitMQ or an older version of Erlang/OTP.
