ERROR: OTP release 20 does not match required regex R16|17

[MUDASSARHASHMI]

I am trying to build Riak from Github source and I am getting this error.

ERROR: OTP release 20 does not match required regex R16|17
ERROR: compile failed while processing /home/osboxes/riak-build/riak/deps/rebar_lock_deps_plugin: rebar_abort
Makefile:23: recipe for target 'compile' failed
make: *** [compile] Error 1

It does takes a lot of time to clone repo to riak/ folder but then it pops a lot of messages about "Missing Plugins.

I know there is no release yet for 16.04 but I thought to give it a try. If this is not the way I should do it then is there any other way around? Can someone please help?

Based on the title of your post, you'll be wanting Erlang 16 which you'll need Kerl for. Please see https://www.tiot.jp/riak-docs/riak/kv/2.2.3/setup/installing/source/erlang/#kerl-prerequisites for details.

You still need basho's OTP16 for riak. OTP20+ support is coming in 2019

[joshzinny]

I am using Erlang/OTP 21 [erts-10.0] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1]

Eshell V10.0 (abort with ^G)

[russelldb]

Yup, that's the issue alright. Riak only supports erlang r16b0something.

[joshzinny]

Is there any work around solution now?

[russelldb]

yes, use erlang-r16. Ideally the basho patched erlang-r16b04-basho10

[joshzinny]

Okay thanks.
