Blockscout: (Mix) Could not compile dependency :libsecp256k1

[AndreiD]

Describe your issue here.

Environment

Ubuntu 18.04

• Elixir & Erlang/OTP versions (elixir -version):

Erlang/OTP 21 [erts-10.1] [source] [64-bit] [smp:1:1] [ds:1:1:10] [async-threads:1] [hipe]

Elixir 1.7.3 (compiled with Erlang/OTP 20)

• Operating System:
  Ubuntu 18.04

Steps to reproduce

Following the tutorial:

On:
mix do deps.get, local.rebar --force, deps.compile, compile

I get:
unicode_util_compat 0.3.1
wallaby 0.20.0
websocket_client 1.3.0
wobserver 0.1.8

• Getting libsecp256k1 (Hex package)
• creating /root/.mix/rebar
• creating /root/.mix/rebar3
  ===> Compiling parse_trans
  ===> Compiling websocket_client
  ===> Compiling mimerl
  ===> Compiling libsecp256k1
  HEAD is now at d333521 Merge #494: Support OpenSSL versions >= 1.1 for ENABLE_OPENSSL_TESTS

  ===> Hook for compile failed!

* (Mix) Could not compile dependency :libsecp256k1, "/root/.mix/rebar3 bare compile --paths "/root/blockscout/_build/dev/lib//ebin"" command failed. You can recompile this dependency with "mix deps.compile libsecp256k1", update it with "mix deps.update libsecp256k1" or clean it with "mix deps.clean libsecp256k1"

@AndreiD
libsecp256k1 is setup to work with rebar, not rebar3.

For rebar3 compatibility edit deps/libsecp256k1/rebar3.config and add the following to the top:

{plugins, [pc]}.

{provider_hooks,
 [
  {pre,
   [
    {compile, {pc, compile}},
    {clean, {pc, clean}}
   ]
  }
 ]
}.

then

1. cd deps/libsecp256k1
2. rebar3 compile

I have no idea what is rebar, and why you need version 3 or 66 or 583.12312
I just followed the tutorial. I don't want to learn what is rebar, nor erlang // elixir.

Can't you do a verified step by step for noobs tutorial, that you make sure it works on a clean install...

It wouldn't hurt to remove so many config files and figure out a system where new people don't get confused on why they need to modify the dev config file or test config file.

I had the same issue, in Ubuntu 18.04 @acravenho I will try it.

Here is a little more background info: https://github.com/poanetwork/mana/issues/415 (different project, same issue)

I appreciate the help. I'll add a fix to the documentation when we can finalize a solution. Sorry for the inconvenience.

BTW I fixed this using apk --no-cache --update add automake libtool inotify-tools autoconf in linux.

Check that you have installed automake libtool inotify-tools autoconf this packages are required to be able to compile project.

Thanks @konstantinzolotarev

Closing this issue due to no new reports.

Ubuntu 18.04, installed tools:
automake libtool inotify-tools autoconf
executing command: mix do deps.get, local.rebar --force, deps.compile, compile
still returns
could not compile dependency :libsecp256k1, "mix compile" failed. You can recompile this dependency with "mix deps.compile libsecp256k1", update it with "mix deps.update libsecp256k1" or clean it with "mix deps.clean libsecp256k1"
Do you have any ideas?
